class features:
Elemental Focuses
At 1st level, Thaumblades can choose two elemental focuses to learn. Their chosen study determines which focuses are available to choose from. When a new focus is learned, you know it as a tier 1 focus, and gain access to its tier 1 ability. When you gain the Focus Upgrade feature at later levels, you can either learn a new focus or upgrade a known focus to the next tier, granting you access to its tier 2, or even 3 abilities.
Spellcasting Ability
Some focus features allow you to cast spells that require spell attack rolls or saving throws. Your spellcasting ability for these spells is Intelligence (spell save DC = 8 + proficiency bonus + intelligence modifier, spell attack bonus = proficiency bonus + intelligence modifier). You can use a weapon with which you are proficient as a spellcasting focus for these spells. If you have spell slots from another class's spellcasting or pact magic features, you can use those spell slots to cast focus spells.
Spellcasting with Vis Points and Spell Slots
Some elemental focuses allow you to cast certain spells. The spells available to cast this way are listed in the focus descriptions, and have their own associated vis point costs.
Thaumblade focus spells are cast at the lowest level for that spell, but can be cast at higher levels for a higher vis point cost. When casting a Thaumblade spell at a higher level, refer to the table below for vis point cost. For example, a Thaumblade with tier 1 Ignis can cast burning hands at 1st level by spending 1 vis point. But if they wanted to cast it at 2nd level, they would have to spend 3 vis points. If they were to cast it at 4th level, they would have to spend 6 vis points.
A Thaumblade can also cast spells gained from another source, such as a feat or multiclassing. Vis points can be used to cast spells up to 5th level that are not part any elemental focuses. The vis point cost is listed in the below table.
| Spell Level |
Vis Point Cost |
| 1st |
2 |
| 2nd |
3 |
| 3rd |
5 |
| 4th |
6 |
| 5th |
7 |
Conversely, Thaumblade spells can be cast using spell slots from multiclassing into another spellcasting class
Thaumblade's Strike
Certain elemental focuses grant you the ability to infuse your magic into a special weapon attack called a Thaumblade's Strike. When you hit a creature with a melee weapon attack, you can choose to use a Thaumblade's Strike that is available to you. Each strike has its own vis point cost, damage, and other effects, detailed in the elemental focuses.
Vis Casting
You have learned to tap into the power of vis, an energy that exists in all material things. This gives you a number of vis points that you can spend to cast Thaumblade spells or use other class features. The maximum number of vis points you can have at each level is shown on the Thaumblade table, and you can never have more than that number. If an ability regains you more charges than that number, those additional charges are wasted.
You regain all expended vis points when you finish a short or long rest.
Thaumaturgic Study
When you take this class at 1st level, choose one of the subclass options detailed below: Elementalist, Praecantator, or Soulbender.
Fighting Style
At 2nd level, you adopt a style of fighting as your specialty. Choose one of the following options. You can’t take a Fighting Style option more than once, even if you later get to choose again.
Archery
You gain a +2 bonus to attack rolls you make with ranged weapons.
Blind Fighting
You have blindsight with a range of 10 feet. Within that range, you can effectively see anything that isn’t behind total cover, even if you’re blinded or in darkness. Moreover, you can see an invisible creature within that range, unless the creature successfully hides from you.
Dueling
When you are wielding a melee weapon in one hand and no other weapons, you gain a +2 bonus to damage rolls with that weapon.
Interception
When a creature you can see hits a target, other than you, within 5 feet of you with an attack, you can use your reaction to reduce the damage the target takes by 1d10 + your proficiency bonus (to a minimum of 0 damage). You must be wielding a shield or a simple or martial weapon to use this reaction.
Thaumaturge Adept
You learn the following three cantrips, which you can cast as Thaumblade spells: blade ward, produce flame, and toll the dead.
Thrown Weapon Fighting
You can draw a weapon that has the thrown property as part of the attack you make with the weapon.
In addition, when you hit with a ranged attack using a thrown weapon, you gain a +2 bonus to the damage roll.
Two-Weapon Fighting
When you engage in two-weapon fighting, you can add your ability modifier to the damage of the second attack.
Focus Upgrade
You can choose a tier 1 Elemental Focus you know, and upgrade it to tier 2, or upgrade a tier 2 focus to tier 3, gaining any abilities the new tier grants and keeping the abilities of any previous tiers. You can also forego upgrading your focus, and learn a new focus at tier 1 instead. You earn focus upgrades when you reach 3rd level, then again at 5th, 9th, 11th, 16th, and 19th level.
Unarmored Defense
Starting at 3rd level, when you are not wearing armor, your AC equals 10 + your dexterity modifier + your intelligence modifier.
Ability Score Improvement
When you reach 4th level, and again at 8th, 12th, 15th, and 18th level, you can increase one ability score of your choice by 2, or you can increase two ability scores of your choice by 1. As normal, you can’t increase an ability score above 20 using this feature.
Using the optional feats rule, you can forgo taking this feature to take a feat of your choice instead.
Extra Attack
Beginning at 5th level, you can attack twice, instead of once, whenever you take the Attack action on your turn.
Spell Dodging
You have honed your reflexes to avoid magical attacks. Starting at 6th level, you have advantage on saving throws against spells and other magical effects.
Chain Casting
Starting at 7th level, when you take the attack action on your turn, you can spend 1 vis point to cast one cantrip with a casting time of 1 action as a bonus action.
Extended Studies
At 14th level, you can learn two focuses at tier 1 of your choice, ignoring subclass restrictions. Alternatively, you can choose to learn one focus at tier 2 instead.
Focuses learned this way cannot be upgraded using focus upgrades or focus mastery, unless they are normally available to your subclass.
Spell Abstraction
Starting at 17th level, you learn Counterspell, and can cast it once without spending any vis points or spell slots. When casting the spell this way and successfully interrupt the target's spell, you regain a number of vis points equal to the level of the target's spell, and temporary hit points equal to four times that amount. After using this feature, you cannot use it again until you finish a short or long rest.
You can also cast Counterspell normally, by spending 2 vis points.
Focus Mastery
When you reach 20th level, choose two elemental focuses that you know, to upgrade to mastery tier. A focus at mastery tier benefits from all features from the first three tiers, as well as special mastery features, listed in the focus description.
Additionally, whenever you cast a spell or use an ability that costs vis points from one of your mastery focus's tier 1-3 features, reduce the overall vis point cost by 1, to a minimum of 0 vis points.
Elemental Focuses
At level 1, Thaumblades can choose two elemental focuses to learn. Their chosen study determines which focuses are available to them. When a new focus is learned, you know it as a tier 1 focus, and gain access to its tier 1 ability. When you gain the Focus Upgrade feature at later levels, you can either learn a new focus or upgrade a known focus to the next tier, granting you access to its tier 2, or even 3 abilities.

subclass options:
Thaumaturgic Study
There are many fields of study when it comes to the essence of magic and protecting the world from arcane threats. Thaumblades can choose one study from the options below.
Elementalist
Elementalists study the various elements that make up the world. Fire, water, earth, air, and more. As a well-rounded unit within the School of Thaumaturgy, elementalists have the tools to deal with a wide array of threats, supernatural or otherwise. Overcoming their foes strengths and exploiting their weaknesses.
Additional Focus
When you choose this subclass at 1st level, you can learn one additional Elemental Focus of your choice at tier 1.
Elemental Damage Types
The elemental focuses used by Elementalists are each associated with different damage types. As you gain levels as a Thaumblade, you will gain features that make use of these damage types. Focuses and their associated damage types are listed below.
Aer: Thunder damage, Aqua: Acid damage, Gelus: Cold damage, Ignis: Fire damage, Tempestas: Lightning, Terra: Poison.
Dominating Element
Starting at 6th level, when you hit a target with a weapon or spell attack and the target is vulnerable to any of the damage types, you may roll one additional die for that damage type.
Elemental Affinity
Starting at 10th level, you gain resistance to all damage types based on the Elementalist focuses you know. After finishing a long rest, you can choose one focus as your primary element, gaining immunity to its damage type instead.
Primal Infusion
Starting at 10th level, you can infuse the power of your primary element into a melee weapon you are holding. For the next minute, any attack made with that weapon deals an additional 1d8 damage, with a damage type matching that of your primary element. The effect ends early if you drop or stow your weapon, you are reduced to 0 hit points, or you dismiss it as a bonus action. Once you've used this ability, you can't use it again until you finish a long rest.
Improved Primal Infusion
When you reach 14th level, your primal infusion becomes even stronger. The additional damage to your weapon attacks increases to 2d8. Additionally, both the weapon's regular damage and the additional elemental damage ignore resistance for the duration of this ability.
Praecantator
Rather than the elements that embody magic, the Praecantator studies the weave and flow of magic itself through the fabric of reality. They are often employed to deal with exceptionally magical threats.
Praecantator Lore
When you choose this subclass at 1st level, you gain proficiency with Calligrapher's supplies. You also learn your choice of either the Mage Hand or Prestidigitation cantrips.
Eye for the Arcane
After reaching 1st level, your understanding of magic has grown to the point where you can identify magical beings, even if their magic is not apparent. When you take the Search action, you can attempt to identify any creatures with Spellcasting, Innate Spellcasting, or Pact Magic features. Choose any number of creatures that you can see, and make an Intelligence (Investigation) or Wisdom (Perception) check against their Charisma (Deception) check. If you beat their roll, you learn whether or not they have a spellcasting ability, but not the nature of their spellcasting, nor do you learn their available spells or spell levels.
Void Scabbard
Starting at 6th level, you can perform a ritual over the course of one hour to bind a weapon to you. It must be a simple or martial weapon with which you are proficient, and must not have the heavy property. Artifacts are unaffected. As a bonus action, you can send your bound item to an extradimensional space that can only be accessed by you. You can also use a bonus action to either draw the weapon from the extradimensional space, or teleport it into your hand, if you can see the weapon and have an empty hand.
When you bind a new weapon to yourself while you already have a bound weapon, your previous weapon becomes unbound, and falls in an open space within 5 feet of you if it is inside the extradimensional space. If you die while a weapon is in this extradimensional space, it appears in a random location somewhere on the same plane of existence where you died, determined by the DM.
Weave-Guided Warfare
Starting at 6th level, your understanding of the flow of magic gives you an edge in combat. When you make an attack roll with a weapon that you are proficient in that does not have the heavy property, you may use your Intelligence modifier for the attack and damage rolls instead of Strength or Dexterity.
Additionally, when you use a strike or cantrip to deal damage to a creature that is concentrating on a spell, the target takes force damage equal to your Intelligence modifier.
Vis Siphoning
Starting at 10t level, you can use an action to regain a number of vis points equal to your intelligence modifier. After using this feature, you can't use it again until you finish a long rest.
Dance of Swords
At 14th level, you can use an action to touch one nonmagical melee weapon you are proficient with, or two if both weapons have the light property. Affected weapons become animated, and count as a tiny construct with 12 AC, 1 hit point, immunity to psychic and poison damage, and a flying speed of 15 feet. This effect lasts up to 1 minute, and requires concentration as if you were concentrating on a spell. It ends early on a weapon if it drops to 0 hit points or is ever more than 30 feet from you.
While you have any weapons animated this way, you can use a bonus action to command them to fly up to 15 feet and make one attack, using your attack and damage modifiers. Animated weapons cannot use strike abilities. Once you've used this ability, it can't be used again until you finish a long rest.
Soulbender
Soulbenders study the energy of life, death, and undeath. Thaumblades who study this field are often the scouts and medics of their organization.
Natural Lore
Soulbenders study the magic in life and nature. At 1st level, you gain proficiency in two skills of your choice from Animal Handling, Medicine, Nature, and Survival.
Linked Essence
Starting at 1st level, you can spend your hit dice during a short rest to restore hit points to another creature within 5 feet of you, instead of yourself. Undead and constructs cannot be healed this way.
Soul Rending
Starting at 6th level, you can turn your own life force into a deadly weapon. As an action, you can touch a creature that is within 5 feet of you, and spend a number of your hit dice. The target must make a Constitution saving throw against your spell save DC, taking necrotic damage equal to the roll on the dice on a failed save, or half as much on a successful one. You can spend 2 vis points to give the creature disadvantage on the saving throw. The maximum number of hit dice you can spend this way is equal to your proficiency bonus, and you regain all expended uses after finishing a long rest.
Life Recycling
After you reach 10th level, when you deal a killing blow to a creature whose challenge rating is at least 1, a fragment of its life essence will appear where it died, and remains for 1 minute. When a creature moves within 5 feet of the fragment, you can force the fragment to absorb into the creature (no action required). When a creature absorbs the life fragment, it regains a number of hit points equal to your Intelligence modifier, and regains one vis point if it has at least one Thaumblade level. This ability has no effect on undead or constructs.
Rapid Recovery
Starting at 10th level, you can focus your energy to accelerate your body's natural healing. As a bonus action, you can spend a number of hit dice, regaining a number of hit points equal to the roll. Using this ability costs 1 vis point, plus an additional point for each hit die spent this way.
Vengeful Essence
Starting at level 14, as an action, you can command any life fragments of your choice that you can see to move up to 30 feet toward one creature and explode, at the cost on 2 vis points per fragment. When any fragments end their movement within 5 feet of the creature, that creature must make a Constitution saving throw, taking 3d4 Force damage plus 3d4 Necrotic damage for each fragment on a failed save, and half as much on a successful one. Any fragments that cannot reach their target dissipate harmlessly at the end of your turn.
