This unit regens 25 flat mana regeneration per 5 seconds and 0.5% of their maximum mana (or energy) per second and has 10% cooldown reduction on their abilities. If slain, this buff transfers to the killer.
with Runic Affinity
The buff is available only on Summoner's Rift. It can be identified by swirling blue runes around the champion. Because of this, it is often referred to as the "blue buff" or just "blue".
How to obtain
- On Summoner's Rift, by landing the killing blow to the Ancient Golem (from which its name is derived).
- By killing a champion that currently possesses this buff. In this case, the duration of the buff is refreshed.
- Due to the large mana regeneration it provides, it is excellent for many casters, especially those with spammable spells or persistent AoE effects such as Anivia, Karthus, Swain, Amumu or Ziggs.
