Dungeons and Dragons - the gunslinger of gungeon reached his maximum level of skills

Gun Mage, best at range but when out of bullets will start using the ability "pistol whip" and "buttstroke."

Commenters note: I'm amazed how centurii-chan never made a joke about pistol whipping or buttstroke with guns, but don't tell her. Let her figure it out herself.

And as I shoot, unlimited GUN works.
