Crimson Rifle

You may spill your blood, or if you are adjacent to a creature that has taken damage in the last round, to create a rifle of red crystal in an open hand. This rifle is a ranged spell attack that you are proficient with which deals 4d10+ spell modifier piercing damage. If the target can bleed, it bleeds 2 points at the start of its next turn per spell level. The rifle has a range of 150ft. The rifle has the two handed and loading properties, but act as a firearm for the purposes of feats and abilities.

You must spend 10 hit points during the casting of this spell, or an adjacent creature must have taken at least 15 points of damage in the last round, to cast this spell. If a creature has taken at least half of the required amount of damage, you may split the difference with half of your cost. Any round you do not deal damage with the repeater, you take 5 points of damage. If using ammunition tracking, the rifle generates ammunition on its own as long as it is fed. If you have physical ammunition to load into the repeater reduce the damage required to feed it by half rounded down.

When using a spell level of 3rd or higher, increase the damage dealt by 2d10, the damage per round by 5, and the initial HP costs by 5.
