Champions that use energy as a resource restore 40 − 50 (based on enemy champion takedowns) energy and can only have a maximum of 250 energy.
With the exception of Shen, who restores 80 − 90 (based on enemy champion takedowns) energy and reaches a maximum of 450 energy.
Presence of Mind is often taken on the Howling Abyss, as the single lane setup causes regular teamfights leading to a lot of takedowns, thus triggering more times than the average Summoner's Rift game.
Removed: No longer refunds 10% of your ultimate's maximum cooldown on takedown.
New Effect: Now also restores 20% of your maximum energy on takedown.
New Effect: Now grants 100 maximum mana or 10 maximum energy on takedown, stacking up to 5 times.
ARAM-Specific Changes: Champion takedowns, after a 1-second delay, restore 10% of your maximum mana or 10% of your maximum energy and increase maximum mana by 50 or maximum energy by 5, stacking up to 10 times for a maximum of 500 maximum mana or 50 maximum energy.
Bug Fix: Many champions whose ultimate abilities use pet controls or multiple activations (e.g. Talon recalling his Shadow Assault or Riven casting Wind Slash) now properly gain Presence of Mind's cooldown reduction on takedowns that occur while their ults are still active.
