Ice-forged Barrier

Envelops you in a Mana-fueled Barrier, protecting you from damage at the expense of mana. Depending on your mana percentage, the Barrier will absorb up to 90% of the damage you take, draining 1 mana per point absorbed. The Barrier also protects you against most effects that would interrupt your ongoing spell cast. Also increases the threat generated by Magic damage significantly but reduces your damage and healing done by 40%. This does not protect you against other players. Being hit by a player will break the shield, stunning you for 5 seconds.

Absorbs damage, draining mana instead. Protected against effects that would interrupt your spellcast. Threat increased, damage reduced.
