Hey!
These drops are useless at a certain point, so I think I'll make their drop rate much lower the further into the game that you are :)
Yeah, I'm still not sure what to do about the other slots, if I do end up making use of them, then it won't happen any time soon, since I'm working hard on adding the shop and fleshing out the weapon parts. Thanks for playing and giving me all the support and feedback, next update releasing soon :)
