Spellcutter

The blade of this +2 greater striking adamantine longsword seems to absorb light from the air around it, giving the impression the wielder is standing in the shadow of a much larger creature.

While Spellcutter is a potent weapon for battling undead and constructs, an ancient restriction on the blade prevents it from harming living creatures; attacks against living beings deal no damage. This restriction doesn't apply to dhampirs or creatures with the ability who are otherwise living; the magic of the blade can't distinguish between such beings and undead.

Activate R envision · Trigger You're targeted by a spell while wielding Spellcutter · Effect Spellcutter attempts to absorb the magic of the triggering spell, giving you a +4 status bonus to your AC and saves against the effect.

Activate 1 Interact · Effect Touching Spellcutter to any light source of 12th level or lower (including 6th-rank spells with the light trait) instantly extinguishes the effect. If the source of the light is a large flame, such as a forest fire or bonfire, it only extinguishes the light source in a 5-foot radius burst from the point of contact.
