Oh, I forgot mention I spend my action in dazed state to use minor action; sustain the aura what he gained from using daily attack. So he needs AP to actually perform his attack. Also I recall from rules or somewhere that certain typed spells do not provoke oppoturnity attacks from foes even if you cast them while adjacent to them (besides all healing abilities). I recall general ruling was that 'any spell which has no range does not provoke oppoturnity attack'. Example Fiery Tempest Breath is close blast 3, meaning I can target 3x3 square area which border/corner must be touching my square where I am standing. It would kill part of spell's potential if I cannot cast it while standing besides enemy and instead spell actual kill area is 3x2 than 3x3 as I would need then have 1 square away from my foe (or more if foe has reach).
