Re: Aegis Thousand Year War - DMM Online Game
Platinum Dragon Shaman Rubinas
Both Rubinas and Echidna are unique in terms of their usage. They are high cost healers that are part time mages. As exkale explained Rubinas has the benefit of being a toggle skill instead of a switch skill.
In return, she looses attack damage compared to Echidna. Considering there's only 3 toggle unit, Kikyou, Rubinas, and the event Healer Juno, they are worth having just for the sake of it. But rarely will you ever 'need' them per say. (All of them happen to have support AW Passives)
Note: Dragon Shaman has a bit higher atk speed than mage, shaman has higher attack speed than healer. Juno's dps otoh is a bit worse than Chloris, and requires 45 seconds to switch back to healing the first time. The short-end of the stick so to speak. otoh, her AW passive is always useful. 7% for healer is more noticeable then other class buffs.
AW wise, both Echidna and Rubinas gives bonus to themselves, Anya, Dragon Riders, and dragon soldiers. Considering how high stats Anya and the Dragon Riders are, they might become useful for creating a dragon deck, but otherwise, not suitable for regular runs.
They are thematic per say.
