Liandry’s Tornment + Frozen Heart on Amumu will PERMANENTLY activate the increased max health per second burn on ANY ability he uses.

A player recently discovered an equipment interaction bug with this champion, causing Amumu to do a lot of damage when combining Liandry and Frozen Heart.

Everyone knows that, Liandry’s Torment Passive: Dealing ability damage applies a damage-over-time effect for 3 seconds that deals a total of 4.5% of target’s maximum health bonus magic damage, with each tick of damage occurring every 0.5 seconds. This total damage is increased to 7.5% of target’s maximum health against Slow icon slowed or Stun icon immobilized units, and capped at 100 damage per second against monsters.

And Frozen Heart: Cripples nearby enemies’ attack speed by 15% (700 range). However, a gamer named max1mum recently posted a video showing that Amumu can fully activate the scorching damage of Liandry’s Tornment to the maximum extent when he owns Frozen Heart in his inventory.

In the video, Amumu only uses the E skill to activate scorching damage to the maximum when owning 2 equipment, absolutely no effect of controlling or slowing movement speed, because Amumu only The only two controlling moves are Q and R.

In a way, when these two items combine with Amumu, the ability to slow the attack attack speed of Frozen Heart is encoded into … slowing the movement speed, causing the passive of Liandry’s Torment  to be activated. Works at maximum damage.

There is currently no confirmation from the Games, but this is one of the serious bugs. Riot will soon detect and fix it immediately to avoid affecting the player’s experience.
