Check out the tooltip for fingers of frost
( Gives your Chill effects a [5%/10%/15%] chance to grant you the Fingers of Frost effect, which increases the damage of your Ice Lance spell by 100% and treats your next 2 spells cast as if the target were Frozen. Lasts 15 sec.)

But the talent calc shows 130% dmg and 25% more dmg for deep freeze ( Guess for pve but if they bring deep freeze dmg back OH HAPPY DAYS)
