Question on Divine mind Ardent

[Hunterx]

Each of these classes gets Mantels to tap into and psychic auras but can only manifest a number of auras at one time. The question is this if you have a mantle but not the aura ability from the class can you take the feat extra aura to gain the aura of that mantel? So would having access to the mantle and the powers be like haveing tap and don mantle feats?

Never mind extra aura only gives you the aura to pick from, not the ability to manifest it.

[Psyren]

Only Divine Minds get the Psychic Aura class feature, so only they can take extra Aura. Ardents and Divine Minds both get mantles, but Ardents cannot gain auras without multiclassing.
