The Blade's Choice

A sentient blade appears before you. Taken
from the tapestries of fate, you and you alone
may wield the blade. You may choose the type
of blade, as well as 1 additional damage type (elemental). However, the blade has a purpose,
and it will demand you fulfill it.

You are proficient with this weapon, regardless
of what it is. It is a +2 weapon.
