I don't think having it be unlimited would not be a good idea. all a person would need is 1. I think if you had the same idea but like a 10% chance (or something low) that will increase the D-Ammy charges to like 20 or something.
Yeah, but if there was a 99% chance to destroy the amulet on an attempt to make (hardened rune is 85% chance), there wouldn't be very many in game, with a 1% chance it may take hundreds of Amulets before you manage to get one. But I'd be up for more charges too. 4 just isn't enough.
Good idea but people would still need dstone ammys for p2p pking and I doubt people would wanna pk with eternal dragonstone amulet
Of course, this would be a pretty rare and expensive item and majority of folks would just use a regular dragon amulet. You don't see people PKing in Hardened/Trimmed Armours either.
