Mana seems to be 'non-elemental'. It's neutral against everything, or at least that is my observation so far.
Also I said I'd look up the specific ranges for Hawk Feather/Awareness, got around to that. You start with a base of 0, which is the default detection range. Awareness adds 1 per character with the ability (It is active both in the active party and in reserve). Hawk Feathers give 4 each.
