Witch bolt

Witch bolt was a simple arcane evocation spell that continuously gave electric shocks to its target.

Effects
The spell created a beam of blue energy from the caster towards a target creature. If the creature was caught in the beam, a sustained arc of lightning was established between the caster and the target, dealing damage for as long as the caster kept concentrating on maintaining the spell, and for as long as a clear line of sight could be maintained to the target, up to a distance of 30 ft (9.1 m).

Components
The spell required verbal, somatic, and material components. The material required was a twig from a tree that had been previously struck by lightning.

History
By the late 15 century DR, witch bolt could be found in numerous spellbooks, such as the one belonging to Grum'shar, a half-orc apprentice wizard who worked for the Xanathar's Thieves' Guild.
