Not really, you have to do full instance to unlock it (or it can be done on normal?)
For the quest, yes. But you don't need to farm it. I saw groups running a full run within 6 hours just for the quest. There is always a way by playing tactics and mechanics or optimising the party setup. ![]()
It is intended to be an upgrade, so no plussing level is transfered. This way everyone can farm the normal artefacts through trashmobs while not being forced to clear the entire instance. But the refined artefacts require loot from the final boss and do require full clears. So if a group of players is not able to clear the entire instance yet, they can still achieve the normal artefacts. And stronger groups can go for the refined ones additionally. Everyone wins.
In that case, maybe the refined one is better than the normal +6?
A little better, of course. Also, the effects of the refined ones will be improved slightly. ![]()
