Evocation cantrip (renaissance)
Casting Time: 1 bonus action
Range: Self
Components: V, S
Duration: 1 minute
You extend your forefinger and thumb, a dangerous
gesture mimicking a gun. For the duration, you can
use your action to make a ranged spell attack against
one creature you can see within 60 feet, dealing 1d8
force damage on a hit.
Your finger gun does not require ammunition,
but is considered to be a firearm for spells and effects
which influence firearms.
The spell’s damage increases by 1d8 when you
reach 5th level (2d8), 11th level (3d8), and 17th level
(4d8).
