2nd-level Evocation
- Classes: Warlock
- Casting Time: 1 attack
- Range: Self
- Components: V, S, M (a charred wooden hilt)
- Duration: Concentration, up to 10 minutes
In place of an attack, you can evoke a whip of pure flame in a free hand. It lasts for the duration and sheds bright light out to a 10-foot radius. If you let go of the whip, it disappears, but you can evoke the Flame Whip again in place of an attack without expending a spell slot.
Whenever you could make an attack, you can instead make a melee spell attack with your Flame Whip against one target within 10 feet that you can see. On hit, it takes fire damage equal to 1d10 + your spellcasting modifier, and if the target is Large or smaller you can instantly grapple it with the Whip.
You cannot attack with the Whip while it is grappling a creature, but a grappled creature takes 1d10 fire damage at the start of its turns and can use its action to make a Strength check against your spell save DC, escaping on a success.
At Higher Levels. When you cast this spell using a spell slot of 4th level or higher, both instances of fire damage dealt increase by 1d10 for every two slot levels above 2nd.
