Theodore's Searing Lash

The arc of your hand creates a whip made of searing hot flame that crackles towards your target. Make a ranged attack against one creature within range, on a hit the target takes 5d8 fire damage and is disarmed.

For the next minute the dropped weapon is white-hot and confers 2d8 fire damage if picked up and disadvantage on attack rolls and ability checks until the start of your next turn

At Higher Levels. Wast this spell using a spell slot of 4th level or higher, the damage increases by 1d8.
