Icy Veins is a level 40 Frost mage ability that increases the casting speed of all spells by 30% and prevents interruption caused by damage while casting for 20 seconds.


Icy Veins is one of Jaina's activatable Talents in Heroes of the Storm.


Under the effects of Icy Veins, spells that normally take 3 seconds to cast will take 2.1 seconds. Spells that were 2.5 seconds will then cast in 1.75 seconds. Spells that cast in 1.5 seconds will then cast in 1.05 seconds.

Icy Veins does stack with [Bloodlust]/ [Heroism], [Time Warp] and [Ancient Hysteria].

Like all haste effects, Icy Veins will speed up all channeled spells, such as [Blizzard]. Note that spells will cast at the faster cast time even if the Icy Veins buff expires while mid-cast or mid-channel, meaning that the buff is effectively longer than the 20 second buff duration. For example, starting to cast a [Frostbolt] with Icy Veins about to expire in half a second will still cast a Frostbolt that finishes in 1.4 seconds.

Like most temporary self buffs, Icy Veins can be used off the global cooldown, and does not trigger it.
