P Rage Gene
Passive
Innate - Rage Gene: Mini Gnar generates 4/7/11 (based on level) Rage over 2 seconds upon dealing or receiving damage, up to 100. Against non-champions, basic attacks on-hit and Boomerang Throw instantly generate「 0.5/0.875/1.375 (based on level) Rage. 」 Against champions, Boomerang Throw instantly generates「 1/1.75/2.75 (based on level) Rage, 」and basic attacks on-hit instantly generate「 2/3.5/5.5 (based on level). 」Boomerang Throw can only generate Rage once per cast, and grants Rage based on the first enemy hit. Gnar's Rage decays after being out of combat for 13 seconds.
At maximum Rage, Gnar's abilities switch to Mega Gnar's abilities, for 4 seconds and until transforming back to his Mini Gnar form, with the exception of Hop, which switches after the transformation. Casting any of them during this time also causes Gnar to transform into Mega Gnar instantly, else he will transform automatically after the 4 seconds have elapsed.
Gnar's Mega form lasts for 15 seconds, with his Rage bar depleting as an indication of remaining time. Rage cannot be generated while in this form. Afterwards, Gnar returns to Mini Gnar, retaining his current percentage health and becoming too tired to generate Rage for 15 seconds.
Gnar gains different stat bonuses based on whether he is in Mini or Mega form. Both of Gnar's forms share their ability cooldowns.
