You can get wearable igon? How??
I'd like to know that too. I know I got it in an early playthrough but I can't remember how or when. And I promised Lacey, so...
Being friendly with Skylar - let her speak her mind mostly. If she likes you enough she gives you igon before you get on the ship (the one cascas tries to chomp). Sorry if that's too vague 😔
