I really hope he requires you to use Relic/Relic Zenith to fight him, and losing means you lose that weapon. It would boost the market for the base weapons for the quest, if nothing else (assuming Relics are still going to be something continually upgraded). Though seeing people lose Allagan weapons would be hilarious... It would beg the question though, what could he possibly reward players with to make fighting him worth the risk? Maybe make him part of the upgrade process for the next tier of Relic upgrades... The Gilgamesh trial drops Radz-at-Han Quenching Oil+1 maybe...
I should stop dreaming, he is part of a sidequest. Zero chance he'll have any impact like that, I should just expect a Trial with Odin like rewards to turn in for vanity weapons...
