wait i dont get how can you raise the shield's strenght if you are invulnerable?, also if you are cc'd and an enemy breaks your shield, wouldnt u be able to cast spells for 8 seconds?.

aside from that i think a better skill to prevent enemies from breaking your shield, ill suggest Lockdown (alternante) to become his ultimate and be like this:

(Active): Averdrian places Astral Barrier on himself and creates a shield on himself for the next 2 seconds that will block the next harmful spell. If an ability if blocked, Avedrian releases a shockwave towards the target, stunning for 1.5 seconds and dealing 200/350/450 (+0.7 ability power) magic damage to all enemies in the shockwave path.

with this even if the enemy team breaks your shield u can use your ultimate to instantly gain a new one and punish any mage that could try to busrt you down.

also i agree with the coments below about changing the shield hp scaling to additional mana or ap (+0.2?) cuz he doesnt use mana.
