Ice Block



Ice Block is a mage spell that gives short-term immunity to all damage and attacks (except priest Mass Dispel and warrior Shattering Throw), at the cost of being able to take no action. Ice Block also purges most debuffs.

Using Ice Block debuffs the mage with Hypothermia for 30 seconds, which prevents him from using Ice Block during that time. This is only relevant for Frost mages with the Cold Snap talent, which will reset the cooldown for Ice Block. It prevents the mage from casting Ice Block, then resetting the cooldown and immediately casting it again. The effect is similar to the paladin debuff Forbearance.

"Ice Block" is often used as a verb, meaning to use Ice Block to avoid an attack, as in "I Ice Blocked that rogue's Eviscerate." When Ice Block is used to remove a debuff, it is commonly referred to as "Ice Blocking out of ~", as in "I Ice Blocked out of sheep."

Equipment
Wearing 4 pieces of Aldor Regalia reduces the cooldown of Ice Block an additional 40 seconds.

With Ice Floes, you can reduce the cooldown of Ice Block to 3 minutes, 20 seconds.

Tips and tactics
Ice Block is useful for escaping from incapacitating effects and crowd-control spells, waiting for your cooldowns, blocking a large single-hit attack (such as Pyroblast, Eviscerate), or buying time for a healer to heal you.

In a one-on-one battle, Ice Block may give your opponent time to cool down abilities, heal, or run. You should rarely let Ice Block expire on its own, but instead cancel when the timing is right, usually immediately after casting.

If used in conjunction with Cold Snap, Ice Block can be used up to 3 times every 10 minutes, and with Ice Floes every 8 minutes.

Ice Block can be used to avoid fall damage (see Blink and Slow Fall for other ways). While Ice Blocked your character falls normally, but doesn't take any damage when hitting the ground. (In previous patches, an Ice Blocked mage would hover in the air, then begin to fall when the spell expired.)

Ice Block will prevent drowning and fatigue damage, and reset the damage counter (not the bar) to zero. You will still lose breath and become fatigued while iceblocked.

Ice Block is powerful enough to remove almost any debuff, including Living Bomb or Baron Rivendare's 45-minute debuff. (However, doing so will not prevent you from completing the 45-minute Stratholme run.) Some notable exceptions are Resurrection Sickness, Vaelastrasz's Burning Adrenaline, Deathbringer Saurfang's Mark of the Fallen Champion and the Deserter debuff from battlegrounds.

Contrary to popular belief, Ice Block will NOT reduce your current threat level. The reason for this misunderstanding is that enemy AI is programmed to ignore you if you are invincible and move on to the next-highest target on its hate list. As soon as the effect fades the enemy may resume attacking you. However, it will prevent you from performing any actions that generate threat, allowing others (who are still attacking, healing, etc) to rise ahead of you on the mob's hate list. Use Invisibility to remove threat.

It is worth noting that a level 70 priest can use Mass Dispel to remove ice block. This may be followed with a Shadow Word: Death for a quick kill if the mage is low on health. Improved Counterspell could be useful here if you manually break ice block while the priest is casting, but act quickly.

Using this macro a mage can instantly stop casting a spell and ice block to protect themselves with no delay. This makes it very useful in PvP or PvE situations which requires you to have fast reflexes to a changing situation.
