Quivaelyn's Sharpening Palm
1st-level transmutation (Artificer,Cleric,Paladin,Ranger)
- Casting Time: 1 action
- Range: Touch
- Components: V, S, M (a whetstone)
- Duration: Concentration, up to 1 minute
You run your palm along a blade, and the magic in your hand gives it a preternaturally keen edge.
Touch one slashing melee weapon. For the duration, attacks with that weapon inflict a critical hit on a roll of 19 or 20.
Once the weapon inflicts a critical hit, the spell ends. If the weapon doesn't inflict a critical hit during the spell's duration, the spell ends with no effect.
After the spell ends, the weapon retains a keen edge for the next 24 hours, as if an expert swordmaster had sharpened it with a whetstone.
