Have pity on the poor Divine Mind ...
... before nijineko says No.
The Don Mantle + Tap Mantle + Extra Aura feat chain
is probably where the waffle-ly wording was pointed.
But it would be nice if something like Divine Mind 4 / Ardent 2
... could skip the Don and Tap feats from the Ardent,
apply Extra Aura directly, and receive the benefits.
Doing it the other way like Ardent 10 / Divine Mind 1
and have Extra Aura feat
s getting a 5' aura on the
Ardent mantles. I don't see how this hurts "the" balance.
You're trading a "spell" for an Aura. Some of the auras
are like 1st level buff powers with Chaining to all party mates.
