Acorn Necklace

This fist sized acorn hangs on a woven rope of vines. The acorn itself gleams golden when it catches the light, and seems to emit a subtle glow at all times. The acorn is enchanted with a modified revivify spell. If the necklace is rested on a dead body, then the acorn dissolves into the person’s chest, and they are restored to life at a d6 per level of hit points. 

Also adds +1AC to the wearer

Notes: Bonus: Armor Class
