Ice Nova & Frostbolt: When cast this way, makes all repeats to expand from Frostbolt along its trajectory. Additional repeats from other sources increases Ice Nova activation rate. Casting Ice Nova this way causes “additional expansions” instead of “repeats”, and therefore do not gain more damage or increased area of effect per repeat, likewise no benefit is gained from Awakened Spell Echo Support’s chance to deal double damage on final repeat. Casting Ice Nova this way also skips the animation chain from additional repeats.
Ice Nova is the only spell that gets a pseudo cast speed boost solely from Pledge of Hands.
