[@Lunarlors34] Nidhogg would basically just gas the entire dome, because it wouldn't hurt him and nobody he cares is inside. However, i think if Cody could make some form of enclosed barrier to keep out the necrotic energy, then they'd just have to worry about bone dust for a bit until one of the stronger mages busts out or deal with it somehow.

It occurs to me Cody doesn't have a spell to do that yet. I only gave him Absolute Defence (the default being he cancels out with magic) and then the variant Shield (solidifies that magic into a strange semi-liquid state) and Wall (similar but stronger due to it not being as flexible and being nailed to a spot).
He's self taught so only has a few spells, was think of maybe creating an armour later. But MUCH, MUCH later. The armour would be OP as crap as it is now, so working on it >.>
His shield and wall don't create a 'dome' so to speak and his absolute defence only works in field of vision. (as do like his entire spell skill set >.> but at least shield can flip around). He MIGHT be able to spread the shield out enough to make a thin dome around himself...maybe. That's it.
