Frost Armor is a passive level 56 Frost mage ability which increases the mage's haste and has a chance to give attackers the Chilled debuff, reducing their movement speed.

Notes

The snare effect is useful for avoiding fighting aggressive mobs you would rather run past, assuming of course they don't resist each time they attack. On foot, a chasing creature will likely get in 2 or 3 hits on the mage (some creatures run faster and swing faster than others) before you outpace them. Mounted characters will usually be hit a single time before getting away.
