I am having trouble remembering which demon armour that is and who it belonged to. I thought Hilton's set was the only set of demon tier armour other the demon tier I can remember the Shield, Amulet, Sword but can't seem to place there being another armour set outside the one Quinn upgraded. Quinn is getting angry and everyone is feeling it.
I'm thinking it's got Alex's signature. Alex made Quinn's second pair of gauntlets and they had a lightning ability and he had dyed them blue. Alex might be his first other friend still alive. Back when Quinn was active a thousand years ago only Hilston Blade had demon tier armour. Alex and one of the first forgers Alex turned into a blood fairy had experience with making demon tier armour or weaponry. Quinn hasn't used the inspect skill yet. but here's to hoping Alex is still around and can upgrade Quinn's gear again in the future.
