Ice Block
Rank 1/1
You become encased in a block of ice, protecting you from all physical attacks and spells for 10 sec, but during that time you cannot attack, move, or cast spells.
Doesn't change the damage or healing of any Mage spell.
Averages, counting crits and misses, for a level 60 Mage with a typical weapon and no other gear or buffs, against a target your level. Worked out from the game's own data, the same way as the Foresight addon.
