Hello,
I'm a new player and I choose to play a mechanic with experimental weapon. I'm now level 3 and I want to upgrade to change my weapon with one of my level.
The problem is my goblin is relatively poor so I want to know if I go from an experimental weapon level 1 to level 3, does the upgraded weapon is free?
If I must buy a new one, can I build a new one and use the old prototype to reduce the cost?
