P Skaarl, the Cowardly Lizard
Passive
Innate: Kled rides his semi-trusty mount, Skaarl. While Mounted, all damage dealt to the duo is suffered by Skaarl, who has 400 – 1400 (based on level) base health; additional sources of health are applied to Skaarl's maximum health. Effects based on percentage health consider Kled and Skaarl's combined maximum health.
Being reduced below 0 health causes Skaarl to flee, forcing Kled to be Dismounted, with all damage in excess of Skaarl's health being ignored. Upon dismounting, Kled lunges in the direction of the allied Nexus, though not through terrain, while cleansing himself of all crowd control and becoming unable to act, untargetable, and immune to crowd control for 0.5 seconds. Dismounting resets the cooldown and charges of Pocket Pistol.
While Kled is Dismounted, his base health and movement speed are reduced; however, he gains bonus movement speed while moving toward enemy champions. Additionally, he gains bonus attack range, and his attacks deal 85% / 90% / 95% / 100% (based on level) damage to champions. Bear Trap on a Rope is replaced with Pocket Pistol, while Jousting and Chaaaaaaaarge!!! become unusable.
While Mounted, healing and health regeneration will first replenish Skaarl's health and will only apply to Kled's health while Skaarl is at full health.
