Nystul's Crystal Dagger

This spell summons into the caster's hand a dagger composed of material from the Quasi-Elemental Plane of Mineral, strongly infused with energy drawn from the Positive Material Plane. The crystal dagger has no attack bonus and inflicts 1d4+2 points of damage in melee.

Against undead and creatures from the lower Outer Planes, the dagger inflicts 1d4+3 points of damage. If the crystal dagger scores maximum damage, the monster is paralyzed until the end of the round following the hit and the dagger vanishes.

The material component is a tiny dagger made from fine lead crystal, worth 250 gp.
