Problem Solver

The Problem Solver is an enchanted firearm is a firearm that does not fire any rounds unless they will incapacitate their target. When the trigger is pulled while the Problem Solver is pointed at a target it cannot take down, the weapon itself will "stack theoretical damage" against that target instead. The amount it stacks is based on the probable amount of damage that the shot would inflict given the user's accuracy and the power of the weapon itself. Once this damage has stacked enough to take down its target, the gun will fire for real and if it hits, the target will certainly be incapacitated and very likely killed.This method of stacking can give the user some leeway against weaker foes as they can make many theoretical shots that are unlikely to hit to stack the theoretical damage while not actually wasting any ammo, then once enough damage has been accrued, they can aim carefully for the kill shot.
When Dual Wielded with the Trouble Shooter, it will gain the effect of stacking its theoretical damage more quickly against more threatening foes.
It is advised that you never point a Problem Solver at somebody that you do not want to kill.
