Resonance is a basic Defence ability that requires a shield and level 48 Defence. When activated, the next melee, magic, or ranged attack received by the player within 6 seconds will heal the player instead of damaging them. There are various attacks that are unaffected by Resonance. The Preparation ability can be used to reduce the cooldown of Resonance by 3 seconds for each attack received.

Resonance shares the same cooldown as Divert.

Mechanics[edit | edit source]

When damage is converted to healing by this ability, the hit will still register, but it is reduced to 1. If the hit is meant to deal 1 damage by any means (including through the effects of Devotion), the player is not healed, the damage is still dealt, and Resonance is not consumed. Disruption Shield, which completely negates a hit instead of reducing it to 1, is consumed by hits blocked by Devotion and Resonance.

Resonance heals from the highest hit taken on any given tick while any other hits deal full damage. It does not prevent stuns, but any damage associated with the stunning attack is healed from.

The amount this ability heals depends on the tier of the shield used, with a healing percentage equal to:

where x is the level of the shield. When a defender, repriser, or rebounder is used, its tier is halved for this purpose. For example:

  • A tier 90 shield will heal 95% of incoming damage
  • A tier 1 shield will heal 50.5%
  • A tier 90 defender will heal as if it were a tier 45 shield: 72.5%

This ignores most damage modifiers, so the relative amount healed is actually higher due to defence/armour damage reduction and effects such as spirit shields being ignored. Prayers and ability-induced damage reduction (such as Reflect) are not ignored, and so will reduce Resonance's healing.

For example, a 2000 hit through 20% reduction and a spirit shield will be reduced to 1120, but Resonance would heal 87.5% (50% + 0.5*75) of the original 2000, resulting in 1750 health being restored.

Yakamaru's attacks are a bit of an outlier as while Resonance will convert the damage into health, it ignores the boss' passive damage multiplier when healing for unknown reasons; therefore, a hit that deals 4,400 damage with a 2x multipler is considered to be 2,200 damage, even though the multiplier is still factored in for the reduced damage.

Interactions with damage[edit | edit source]

This section documents examples of how various types of damage interact with Resonance.

Against the following typeless damage, Resonance will heal from it as usual:

Resonance will block damage but heal a "0" against the following typeless attacks, which are called soft typeless damage. Other defence abilities can reduce this kind of typeless damage if Resonance can block it.

Melee, magic, or ranged damage that Resonance, other defensive abilities, and most forms of damage reduction cannot affect include:

Before an update in 2019, the following examples belonged in the previous group, ignoring Resonance and most forms of damage reduction. Said update changed these attacks to behave as standard melee, magic, and ranged damage, allowing them to interact with forms of damage reduction like normal.
