Jester

 This is the main page of Jester's level 16 character sheet, for personal reference.
What does this mean in the context of journal RP?  Well, not much.  But some elements may make it into RP, like so:

AC 20 - This just means that Jester is hard to hit.  She wears armor and carries a shield.

Hellish Resistance - Jester's unusual tiefling/water genasi heritage gives her resistance to cold damage, rather than fire.  Frost-based attacks don't hurt her as badly, and she is unbothered by chilly weather and rain that makes her friends miserable.

War Caster - This indicates that Jester is used to using magic in high-pressure combat situations.  She's quicker, more focused, and more adaptable than the average magic user.  She's able to concentrate on her spellcasting even through the pain of battle wounds, and is able to think and cast quickly to take advantage of even a moment of inattention from an opponent.
