Ratatoskr spawns with a powerful Magic Acorn from the World Tree in his inventory, replacing his item slot for boots. He can upgrade this acorn through the item store from anywhere on the map to increase his Power and Movement Speed. The fully upgraded acorn heals him when his abilities successfully hit enemies.
Ability #1 Dart
Ratatoskr dashes forward, damaging and slowing enemies for 3s. Dart pierces through minions and stops at the first god hit.
Also, Dart's cooldown is reduced by 2s for each enemy god hit by Flurry or Acorn Blast.
Ability #2 Flurry
Ratatoskr spins around in a flurry of attacks, damaging nearby enemies and reducing their Physical Protections up to 4 times.
Ability #3 Acorn Blast
Ratatoskr shoots a blast of three acorns forward in a cone, each dealing damage. Enemies hit by more than one acorn will take additional damage and enemies hit by all 3 acorns are stunned for 1s.
Ability #4 Through the Cosmos
Ratatoskr charges up then leaps from the ground to a branch above his head. He may jump to 2 more branches before choosing a landing location. Upon landing he deals damage and Knocks up enemies. Through the Cosmos can be canceled or timed out from any of the branches, causing Ratatoskr to strike down at the current target location. Jumping all 3 times will result in a larger hit radius.
