All right here me out. Here comes a terrible idea, but guns could have a set damage.
You are maybe thinking “but how do you increase the damage of a gun? and why do you have such a terrible idea”
you could replaces the gun with a better gun or infuse magic with it to make harder bullets or make them faster. Guy works out at the gym for 7 weeks to find out that his gun does not do more damage
(If you find this a bad idea or offensive to your loadout. consider it a joke)
I think this is a good suggestion because it’d force people to actually farm crowns and buy stuff to deal more damage, instead of just farming XP and your damage growing with your level. Also, new players have a chance to get super OP for their level if they have crowns.
