Sometimes you spend pearls upgrading something that becomes obsolete. It would be nice to be able to extract some pearl value from those wasted forges.
Since it usually takes 2 tries to forge anything, if we would just get back half of what it cost us in pearls to forge the item/troop/item/spell.
Example: Lightning tower with 20 forges that I don’t use anymore. Unforge option would give me back half of what I spent in pearls on the item and bring the forges back to 0. Even a 25% pearl return rate would be reasonable. So if it cost around 10,000 pearls to get to 20 forges on that lightning tower, maybe get 5,000 pearls back? or 2,500? and it would become a normal unforged lightning tower.
This is just an example, whatever would be easiest to implement would be fine, but I think it’s a good idea. It’s more of a late game thing, but many would be interested I think.
