Durability system to temple prosthetic limbs

Just ripped with 3 half decent limbs the other day (10% attack speed, 7% dmg recoup as life, and reduced penalty of attacking while moving) and it just felt draining knowing that was essentially wasted time.

I think that a really good change they can do is add durability and a room that can repair broken limbs or even juice them up further if thats something they wanna do. If multiple limbs needed repaired youd need to pick and choose which one to repair first for the most impact. Or grind more temples to get another repair room.

I think thematically as well it would fit the whole doryani mad scientist vibe too. I dont wanna just crash out about that time waste but rather provide a change that would make me wanna grind more temples and not complain as much.
