I think we should be able to remove runes that we have applied to weapons without destroying them. If you are extracting the base rune from a weapon I think it is fine to have that destroy the weapon. This would allow us to test out different moves without bricking the weapon.
For example, I put fire throw on my halberd and it does nothing. I wasted a rune slot and the weapon is much worse than it could have been with a rune that actually does something. I don’t know if throw runes are supposed to do nothing on two handed weapons but if so, don’t let us slot it in.
I also wasted 4 gems on this item. It just feels bad to get good rolls on an item, then put a rune in that does nothing.
Currently there is no way to view what runes do other than going on YouTube. Hopefully we can preview rune attacks before applying them if we aren’t going to allow rune removal without destroying the weapon.
