Ice Lance is a core mage ability learned at level 22. It deals Frostdirect damage. The spell can be powerful due to the fact that it deals quadruple damage to targets that are frozen.
Use: Permanently teaches you this glyph. Your Icy Veins causes your Frostbolt, Frostfire Bolt, Ice Lance, and your Water Elemental's Waterbolt spells to split into 3 smaller bolts that each do 160% damage, instead of increasing spell casting speed.

Notes
The quadruple bonus on frozen targets is applied after all spell damage, talents, and other modifiers have been calculated. The spell damage coefficient is very low, only 14.29%,[1] however when quadrupled on a frozen target, the effective coefficient would be 57.16%.
Tips
Ice Lance is a great source of burst DPS in solo, PvP, and some group situations. It is useful in any situation where an enemy can be frozen, which makes it less useful on most dungeon bosses. Since the damage bonus is applied after all other flat modifiers such as spell damage effects, the burst damage can get pretty high.
Ice Lance is one of the offensive mage abilities that can be used while moving, and the fact that it has no cooldown other than the global cooldown means that it can be spammed repeatedly. Interestingly, it is possible to use Ice Lance to make a "fighting retreat" so to speak and use it on foes directly behind the mage's path of movement. The trick is to face perpendicular to the target that you wish to flee from and side-step out of the way. Thus, if you face left with the target to your left, move to your right, and if you face right with the target to your right, move to your left. The actual targeting arc for spells and abilities is 180 degrees in front of a character, so by "torso twisting" in this manner a mage can run away at full speed while still showering the foe with Ice Lance attacks.
On non-frozen targets, the spell is a useful instant that costs very little mana. Unlike wanding, Ice Lance can be cast while running. In PvP, use it to take down shaman totems or to interrupt flag captures in battlegrounds.
Summon your minion. From a decent range(~20y), target your enemy and begin casting your [Frostbolt]. While Frostbolt is casting, use the minion's Freeze on your enemy, and immediately when Frostbolt is done casting start spamming Ice Lance. Because of the distance and travel time, Frostbolt and Ice Lance should hit at the same time and both crit, leading to burst damage of up to ~5000.
