There are some ancient jaror something like that that you should be able to destroy for coin drops, but it seems that the archer basic skill doesnt hit them, is it a bug?
the beginning part feels too prolonged. i feel so slow and weak, and as a result, it takes a long time to clear the whole thing. i wonder what permanent stats to level up using those eternal stones in order to speed up the early game of this dungeon. i would guess attack and speed probably.
I personally don't need them on my Kronos account. But my Hyperion account is worth doing. Very good for newer players than more established ones. But free rewards are free. The flames and symbols are nice for even end game players yet it's not much. But it is free
It doesn't matter. You can claim the rewards and they are tradable. What matters is what character you do the event on since you'll play as that same class.
