I'm trying to understand how repairing items works in Divinity: Original Sin. It seems like I just need a repair hammer and a low level in blacksmithing to repair higher-level items any time I like with no negative effects, which seems too easy, especially since durability seems to be the main mechanism for preventing brute-forcing through every chest and door. So, to make sure:
- What, exactly, is required for fixing an item?
- In terms of equipment needed, skills needed, etc.
- And what is the precise dependency on item level / value / type / whatever
- Is there any potential downside to fixing an item too often or too little?
