Modifiers

Frostmourne Buff

Any

Frostmourne Debuff

Any

The curse that slows an enemy, speeds an ally.

• This ability got reworked into the current Curse of Avernus in the 7.20 gameplay patch.

• On each successful attack, Abaddon places a debuff on the target which slows them.
  • The attacks first apply the debuff, then their own damage.

• Every allied unit which starts attacking a unit which has the Curse of Avernus debuff on, gets the speed increasing buff.

• This means it does not matter if Abaddon is still attacking the unit. As long as a unit has the debuff on, allies get the speed buff upon attacking it.

• The slowing debuff can be placed on buildings, but cannot be placed on wards or allied units.

• The speed increasing buff is not applied on buildings, wards or enemies attacking a debuffed unit.

• Abaddon himself always gets the speed increasing buff upon starting an attack, regardless of the debuff, except when the attack target is a building.
  • However, after having placed the debuff on a building, Abaddon gets the buff like how allies do upon attacking it.

• Successive attacks on the same target do no stack, but refresh the duration instead. This goes for the buff and debuff.

• Choosing the slow upgrading talent does not affect any of Abaddon's currently placed Curse of Avernus debuffs.
