The ice one? You're creating an invincible for mages, and since it's only used in panic moments, it would probably have to be fairly fast cast. This could be potentially abused by TAing a lot of hate onto said mage, having them put up invincible, and heyo, invincible non-acting tank.
Plasma shield - How would this work? Why would it reduce the effectiveness of status ailments? The RP aspect of it aside, giving a "Resist All I" trait via spell seems way OP, especially when we have spells for individual resistances that don't stack with each other (element on element or debuff v. debuff... you can have barparalyze/barblizzard up at the same time, for example).
Noctowall - Waaaaaaay OP. Too many buffs for a single "defensive" spell.
