Debilitate is a threshold Defence ability. When activated the target takes 20–100% weapon damage and any damage they deal to the user is reduced by 50% for 7.8 or more seconds, depending on if they're wielding a shield as well as the tier of the shield equipped. For every 10 shield levels, 0.6 seconds are added, and the Bulwark perk can further increase the duration. Alongside reducing normal damage, Debilitate also works against soft typeless damage, but not hard typeless damage.

Usage[edit | edit source]

Debilitate only affects the user - even though the icon may appear for other players, they will take appropriate damage as usual.

If the player uses Debilitate against multiple enemies rapidly (only possible with Raids armour), then Debilitate will only affect the recently struck target. As with most defensive abilities, the effects of Debilitate can be removed if the monster possesses a mechanic that can reset defensive abilities.

Fortitude increases the accuracy of this ability by 10%, making it more effective than Turmoil and equivalents, but less effective than Malevolence and equivalents. The Shield Bashing perk increases the damage of this ability by 15% per rank.

In addition to reducing damage from the struck target by 50% towards them, Debilitate's duration is dependent on the shield tier being used. If a shield-enhanced Debilitate is used but the player switches it for something that would replace that shield, Debilitate's effects are immediately removed from the target. Therefore, the ability should only be used in full either without a shield or with the best shield the player is using; for the latter, it should not be switched out until the effect expires.

Trivia[edit | edit source]

  • For a time after the Evolution of Combat, this ability only worked with melee and ranged weapons. Mages attempting to use this ability would go up to melee distance and use this, and it would rarely hit because magic weapons have no accuracy with melee attacks. This glitch has been fixed.
  • If the player uses Debilitate with two-handed weapon and switches to a main/dual-wield, then Debilitate's effects will still be retained. However, switching back to the two-handed weapon will remove its effects. The same applies when the player uses a main/dual-wield weapon and switches to a two-handed weapon.
