It would be nice if we could augment capes since they are a large item worn (unlike gloves, boots, and helmets). A limit of one perk doesn't sound too bad or OP, maybe could be a perk that doesn't affect DPS.
Anyway, as for the micro gizmos, I was thinking that invention goes up to level 150, so why not expand with stuff we can augment boots, helmets, and gloves.
Or stronger perk combos, like p6a4 idk. Just throwing some ideas out.
Any suggestions are welcome.
