There used to be a mod that made Gladio invisible (his sword was visible in combat still heh), but the author removed it at some point. I really miss that mod.

The one for Prompto and even the one for Noctis still works tho.

Anyway, I know it's a super long shot, but if anyone could make a new mod to make Gladio invisible and upload it to Workshop, I'd be eternally grateful.... I don't care about one for Ignis (heh) but some might so one for him would be fair, too.
