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

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 via the effects of Devotion, Resonance will not be consumed. Disruption Shield, which completely negates a hit instead of reducing it to 1, is consumed by hits reduced by Devotion and takes priority over Resonance.

Resonance heals from the first 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:

Healing%=50+(0.5×x)

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 multiplier is considered to be 2,200 damage, even though the multiplier is still factored in for the reduced damage.

Interactions with damage

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:

• Araxxor and Araxxi's poison
• Telos' typeless font absorption damage in the fourth phase (excluding the final hitsplat of a given font)
• Deflect damage from most sources (Mirrorback spider, deflect curses, cobweb shield)
• Solak's blight damage

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.

• Raksha's tail swipe
• Nomad's autoattack and Soul Blast
• Vorago's Vitalis-spawning orb
• Helwyr's damage over time attack
• The Twin Furies' channelled bomb
• Telos' uppercut, prayer disabling jump, red shockwaves, So Much Power, weak anima bomb, tendrils, rockfall, and virus
• Nex: Angel of Death's instant kill pulse bomb, elements quadrant damage, and amalgamation spawn explosion
• Penance King's attacks and King spawns' explosion
• Lucien's "You dare attack a god?" attack
• Normal mode K'ril Tsutsaroth's prayer smash
• Solak's anima mines and spore bomb followup
  • Damage taken from healing Solak's consciousness
• Astellarn's solar storm
• Verak Lith's ice, shock, and poison energy
• TzKal-Zuk's empowered magic bomb

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

• Magic red bombs summoned by Gielinor in the Memory of Nomad
• Magic damage from Verak Lith's flame vortices
• Sliske's magic shadow hand attack
• Ambassador Jabari's magic attack

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.

• Melee damage taken by being in the path of a charge from Tuz, Krar, or Cormes
  • Magic damage from bombs thrown by Beastmaster Durzag
• Nex: Angel of Death's ice prison melee bleed and magical smoke walls
• Vindicta and Gorvek's magical fire walls
• Black stone dragon's magic shadow bombs

Bone Shield use

This table shows the ability scaling and cost when used with Bone Shield.

Ability		Scaled effect	Greater Bone Shield			Lesser Bone Shield
			Level 120 (tier 60 shield)	Level 120 + (tier 75 shield)	Cost per cast	Level 120 (tier 30 shield)	Level 120 + (tier 45 shield)	Cost per cast
	Debilitate	Duration of damage reduction	12s	12.6s	0	10.2s	10.8s	0
	Resonance	Healing from prevented damage	80%	87.5%	7,220	65%	72.5%	2,210
	Divert	Adrenaline from prevented damage	39.9%	45.6%	7,220	32.3%	36.1%	2,210
	Barricade	Duration of damage immunity	8.4s	9.0s	7,220	6.6s	7.2s	2,210

The following defensive abilities do not scale with shield tier, but Bone Shield allows them to be used: Preparation, Reflect, Immortality, and Rejuvenate.

The following defensive abilities require having a shield equipped, therefore cannot be used with Bone Shield: Bash and Revenge.
