1/3/12 Amiti, Gold lumps raise the QL of a door, or "repair" them, at any QL, even a 1 ql lump repairs the door some, doesn't it?
:Lump ql and blacksmithing skill determine the maximum strength you can improve a door to. The formula is 100*(lump QL/4 + Blacksmithing skill/2). Assuming 50 BS skill and 1QL lump the maximum strength is 2525. A 40QL lump would allow imping to 3500. Trying to improve higher than the maximum will result in a message that the skill or materials do not allow improving the mine door any higher. [[Mine door (silver)]] has all the maths around improving although the information should probably be moved to a more general [[Mine door (metal)]] page. --[[User:Ago|Ago]] ([[User talk:Ago|talk]]) 19:59, 3 January 2013 (CST)
OK, so I see what was "confusing" it was imping, just not as high as it could. Thank you for the clarification.
