Expert Tips
- Snowball (Q) consumes a monster, minion, or champion. Always Q the jungler for 40% HP restoration.
- Blood Boil (W) is your team speed booster. Activate it on the fastest/most mobile ally, not yourself.
- Absolute Zero (R) is interruptible. Cast it in a bush or fog of war; never in open terrain where they can walk out.
