Thread: Gold Crystals

Aria - Good gold soldier with global ATK boost as AW passive. Also easier to mincost than Katie depending how much you invest on her in this revival. She will be useful for maps that require early deployment and UP generation.
Echidna - dragon shaman that works similar to a bishop. Her S.AW turns her into a pure healer with increase defence. I don't use this class much, so I can't tell you anymore than that.
Time fairy - a must since she is required to "CC" Dorania. If you get more in the future (since you can only get one per revival event), she is useful for a guaranteed CR. Veterans suggests you use her on premium blacks who need one more CR for mincost.
Dorania - Anya's sealed form. You need this and time fairy to get Anya, so 800 RCs actually.
