Wrench

The wrench is an item, it is used for repairing buildings by giving them back resistance.

You can buy it in a workshop for 50 gold ore. It has limited durability (but it is not the case because of a bug) and is not stackable.

Effect
Active, if you left-interact on a damaged building, it will get 5 resistance (or remove 5 damages) back every 0,666 seconds but it will cost you 2 gold ore per action. It will not work if you don't have enough gold in your inventory.
