The default settings kidding us to only get 4 slots now for a level 6 tool/weapon. Seriously? This is not good. Took away the ability to craft level 6 things. Fine. No problem. Limiting the max amount of mods? Even for top tier things? No. With this 7 Days to Die mod, Level 6 thing = 6 mod slots. Level 5 thing: 5 slots, and so on. Very useful.
The forum topic of the mod is here.
