Human (Mark of Sentinel)

Sentinel's Intuition. When you make a Wisdom (Insight) or Wisdom (Perception) check, you can roll a d4 and add the number rolled to the ability check.   Guardian's Shield. You can cast the shield spell once with this trait, and you regain the ability to cast it after you finish a long rest. Wisdom is your spellcasting ability for this spell.   Vigilant Guardian. When a creature you can see within 5 feet of you is hit by an attack roll, you can use your reaction to swap places with that creature, and you are hit by the attack instead. Once you use this trait, you can't do so again until you finish a long rest.   Spells of the Mark. If you have the Spellcasting or the Pact Magic class feature, the spells on the Mark of Sentinel Spells table are added to the spell list of your spellcasting class.  

Languages. You can speak, read, and write Common and one extra language of your choice. Humans typically learn the languages of other peoples they deal with, including obscure dialects. They are fond of sprinkling their speech with words borrowed from other tongues: Orc curses, Elvish musical expressions, Dwarvish military phrases, and so on.
