Projector tank, cryo

When triggered, this vapor projector ammunition produces a beam of carbonite energy in a line 15 feet long and 5 feet wide or a 15-foot cone. A single fuel tank holds enough fuel for three attacks in a line or a single attack in a cone. Each creature must make a DC 14 Constitution saving throw. On a failed save, a creature takes 2d4 cold damage and gains 1 slowed level until the end of your next turn. On a successful save, a creature takes half damage and isn't slowed. If this damage reduces a creature to 0 hit points, that creature is frozen in carbonite for 1 hour.
