Damaging an enemy champion increases your mana regeneration by 1.5 − 11 (based on level) mana per second, reduced to 80% effectiveness for ranged champions, for 4 seconds. When triggering this effect, energy users regenerate 1.5 energy per second, instead. Takedowns restore 15% of your maximum mana or 15% of your maximum energy.
Increases mana or energy pool on takedown instead of refunding ult cooldown. Now restores energy in addition to mana.
This rune's ult cooldown refund overlaps too much with Cloud Drake's new buff. Admittedly, so does Ultimate Hunter, but Hunter is usable by more champions and has a clearer goal, so it's the one that gets to stay. We're changing Presence of Mind to finally open it up to energy users and grant a resource pool increase (big brain getting bigger) rather than a partial ult reset.
TAKEDOWN BONUS : [Restore 20% of your maximum mana and refund 10% of your ultimate's cooldown] ⇒ Restore 20% of maximum mana or energy and increase your maximum mana by 100 (up to 500) or your maximum energy by 10 (up to 50)
BUGFIX : Many champions whose ultimate abilities use pet controls or multiple activations (ex. Talon recalling his Shadow Assault or Riven casting R2 - Wind Slash) now properly gain Presence of Mind's cooldown reduction on takedowns that occur while their ults are still active
Enemy takedowns restore 20% of your maximum mana and refund 10% of your ultimate's cooldown.
Presence of Mind is extremely valuable on some champions and barely noticeable on others. Specifically, champions with long cooldowns can't benefit from its current effect, so we're moving it back to a more generic power that is consistent across all champions.
THE ULTIMATE MANA REFUND : Enemy champion takedowns restore 20% of your maximum mana and refund 10% of your ultimate's cooldown
This is our first wide balance pass on the Runes paths! We've got a few case-by-case contexts in the tabs below, but are otherwise focused on ensuring no one option in any given row is overpowering its neighbors.
DURATION :  ⇒ 7 seconds
UNLIMITED POWAH For 5 seconds after gaining a level or takedown any mana you spend is fully restored
