Second Relic Weapon

[Kairgon]

I assume so. I was actually wondering if it would be possible to get 'relic ready' with multiple classes at the same time, do the fights, and get credit for all at the same time with a single fight (I.e. 1 titan HM and finish drg, whm, and smn relic at the same time).

You can't, since you need to get credit by which class you are ON for quest.
Yes you can get 2nd quest for relic, I assume it'd just same way you did with 1st relic one. Sorry didnt got second 50 level yet, but I'd assume so.
