Summoner Initiate

Must have at least a 14 in Intelligence or Charisma; Can't be a servant

You learn some basic knowledge on what it is to be a summoner, however you've yet to achieve the full capacities of a summoner.  

• You learn 2 cantrips and a spell based on the spellcasting ability (Wizard's list for Intelligence and Sorcerer's list for Charisma)
• You gain 3 Command Seals and can summon/form pacts with servants. Servants level up based your total character level and use your Intelligence or Charisma spellcasting modifier for DC's and similar abilities.
• Your Mana Supply is determined by your Spellcasting Modifier + your level. Even if you already have spellcasting, you can't convert spell slots to Mana points. If you already have a mana supply, you instead gain a bonus to your mana supply equal to your Summoner level.
