"The Chosen Caster"

As Blake dashed towards Grim, his magical barrier enveloped his body and transformed into a full body armour. His sword glowed brighter as shards of ice spawned from his armour. A nearly indestructible armour made of scales of the frost dragon covered his body. His shoulder armor grew spikes and blades as he repeatedly slashed Grim with his frost sword. The magic of a thousand caster he acquired intensified his frost magic, he can fully control each cast without fainting. His true magic is being releaded.
