Weapon

Uncommon

Any weapon.

When your attack roll is one point away from landing a critical hit, once per long rests, you can choose to critically strike the target instead.
When you do so, the weapon corrects its own trajectory to guarantee a critical strike.


This can happen a lot of ways, some examples:
-A soul fragment of an ancient master has been attached to the weapon, remembering its way to strike true and never miss its target.
-Runes are carved into the weapon, when activated the runesslightly alter the weapons trajectory.
-A sentient weapon, helping its user.
