Frostbolt grants you Fingers of Frost and Brain Freeze 20% more often.

All of your chilling effects reduce the target's movement speed by an additional 15%.

Your Ice Lance and Icicles now deal 5% increased damage, and hit a second nearby target for 80% of their damage. Your Ebonbolt and Glacial Spike also hit a second nearby target for 80% of its damage.
