Vorkath uses all three combat styles, but it can only melee you if you are standing right next to it (including diagonally). Its attack rhythm is fixed and learnable: six random standard attacks, then one special attack, then six more standard attacks, then the other special attack, alternating between the two specials until the boss is dead. Vorkath attacks on a speed-5 cycle. Below is each attack you will face.
Standard attacks (Melee, Magic, Ranged)
The three basic attacks deal up to 32 melee, up to 30 magic, and up to 32 ranged damage respectively. The magic attack is used more frequently when you are in melee distance; the ranged attack is used more frequently when you are out of melee distance. Crucially, these standard attacks are unreactable — you cannot respond to the projectile after it is fired, so you should constantly pray against the attack style you are weakest to. With a crossbow and a dragonfire-protecting shield, that means Protect from Missiles; with melee, a blowpipe, or a book of law, that means Protect from Magic.
Standard dragonfire
Standard dragonfire deals damage that scales with how many layers of dragonfire protection you stack. Full mitigation needs a super antifire potion together with a dragonfire-protection shield. The common, practical combinations — a regular antifire with a dragonfire shield, or a super antifire with Protect from Magic — both reduce the dragonfire max hit to 10.
The special dragonfire variants
Beyond standard dragonfire, Vorkath has three advanced dragonfire attacks, and not all of them are stopped by antifire:
- Venomous dragonfire — inflicts venom if you are not immune. Dragonfire protection negates the damage but does not stop the venom, which is why you bring anti-venom or wear a Serpentine helm.
- Corrupting (prayer-disabling) dragonfire — deactivates all your prayers on impact. Set your quick-prayers so you can flick everything back on instantly. Protection negates the damage but not the prayer-disabling effect.
- Deadly dragonfire — launched vertically at the tile you are standing on when it fires. If it hits you directly it will often outright kill you; if you are adjacent to the strike zone it deals half damage. No type of dragonfire protection defends against this attack, so you must always be ready to click two tiles away from where you stand.
Rapid Fire (acid pool special)
Rapid Fire is the deadliest of Vorkath's attacks and one of its two rotating specials. Vorkath launches acid pools around the arena (one lands where you were standing), then fires dragonbreath every tick at the tile you are on. Standing on or running over an acid pool deals up to 10 damage, which Vorkath leeches back as its own health. Getting hit by the rapid-fire dragonbreath deals 25–41 damage regardless of your dragonfire protection. The way to survive is to keep moving by walking on clean tiles — find a line of at least five acid-free tiles and walk back and forth along it. During this special, Vorkath has a flat 50% damage reduction, so you deal half damage while it is active.
Zombified Spawn (freeze special)
Vorkath's other special launches an icy breath that deals no damage but freezes you in place, then spits out a Zombified Spawn that always lands ten tiles away and walks toward you. The moment the breath is launched, Vorkath becomes immune to damage and stays immune until the spawn is dead or has exploded. The spawn has 38 Hitpoints. If it reaches you it explodes, dealing damage based on its remaining Hitpoints — up to 60 damage at full health. Casting Crumble Undead instantly kills the spawn and always hits, provided your Magic attack bonus is above −64. Because Vorkath is immune the instant the breath fires, do not keep auto-attacking after the sixth standard attack — turning auto-retaliate off and eating or drinking when the icy breath lands stops you wasting attacks on the immune boss and buys time to land Crumble Undead.
