Garen regenerates 2 / 8% of his maximum health per 5 seconds after not receiving damage for 9 / 4 seconds (at levels 1/11). The regeneration increases to 4 / 16% maximum health per 5 seconds when Garen is below 25 / 50% health (at levels 1/11). Until level 11, the regenerative state will stop if Garen receives damage from any source other than lane minions. After that, Perseverance is also no longer removed by non-epic monsters.
