Briar Vinestorm

Synthesis. Briar can subsist without eating food so long as you have access to sunlight for at least 8 hours in a day. Additionally, while you have at least 1 hit point, you produce an envelope of fresh air up to 10 ft. around yourself which can sustain yourself and one other creature indefinitely (this feature works for example in voids and in caves with unbreathable air, but not underwater).

Flourishing. When Briar makes a skill check using charisma, or a charisma saving throw, you can roll a d6 immediately after seeing the number on the d20 and add the result  to the check. You can use this feature a number of times equal to your proficiency bonus, and you regain all expended uses when you finish a long rest.

Archery. Briar gains a +2 bonus to attack rolls made with ranged weapons.
