Nunu & Willump

Strengths

Consume allows Nunu to stay in a lane against ranged opponents.
You can choose to interrupt Absolute Zero early for partial damage if an opponent is about to run out of range.
It's often beneficial to delay the casting of Absolute Zero until the initial round of disables are used. Try to hang back before rushing into a team fight.

Passive · Call of the Freljord — Nunu increases the attack speed and Move Speed of Willump and a nearby ally, and causes Willump's basic attacks to damage enemies around the target.
Q · Consume — Willump takes a bite out of a minion, monster, or enemy champion, dealing damage and healing himself.
W · Biggest Snowball Ever! — Willump creates a snowball that grows in size and speed as he rolls it. The snowball damages and knocks up enemies.
E · Snowball Barrage — Nunu throws multiple snowballs that damage enemies. When he's finished, Willump roots any champions or large monsters that were hit by a snowball.
Ultimate · Absolute Zero — Nunu & Willump create a powerful blizzard in an area that slows enemies and deals massive damage at the end.
