On the basis that these would be fairly recognisable in association with Jayem, since he got two during his newbie quest on Avlis and one was upgraded as the final reward to that, I think I shall share.
The armour he has to wear at almost all times due to the ever present threat of fairy tickling. Unfortunately neither the resistance to swords it had originally nor the acid and negative energy resistance he had added in Mikona (thought the negative would replace the acid) nor even the resistance to magical energy that a visit to Innocence Lost provided have any effect against such a terrible threat.
The shield that makes the glowy-trolls drip-drip of elemental damage less of an irritant.
And the sword he has had for rather a while both as this and for a time simply as "Feysteel Bastard Sword"... though in all the time since it was upgraded and named he has never decided if the stone visibly set into the blade does pop out and go whizzing around him when he triggers the Ioun Stone power or not.
