Phantom Muspah has 3 forms; ranged, melee, and shielded. It will switch after taking 100 damage in the ranged form and 80 damage in the melee form. Every time it changes form, it will slam the ground, creating spikes around the arena; one on the player’s position and a few elsewhere. Standing on a spike will heal the boss for 75% of the damage dealt and knock the player back.
Phantom will start with either ranged or melee form.
In its ranged form, it will attack the player with both ranged and magic. Ranged attacks are more common and can deal up to 61 damage, so protect from missiles should be active by default. The Phantom Muspah will always charge up for his magic attack by standing up and charging a purple orb before launching it at the player. Players should use Protect from magic as soon as they see this animation, as failure to do so can result in up to 72 damage. The magic attack will also apply corruption on the player, draining 3, 6, and 9 prayer points every 6 seconds, for a total of 18 prayer points in 18 seconds.
Strategy for this form: Attack it with ranged while praying against missiles, and watch out for the magic attacks it will use occasionally.
In Phantom Muspah’s melee form, it will attack with melee, which can deal up to 34 damage. Players can avoid damage from this attack by praying against melee and moving one tick before the attack is performed. If done correctly, Muspah will chase and attack the player in the same tick for 0 damage.
Strategy for this form: Pray against melee, freeze the Muspah in this form and attack it with magic. It will break free after a while, so be ready to freeze it again
When Phantom Muspah reaches less than 127 health, it will become shielded, immune to all regular sources of damage, and release a massive shockwave that engulfs the entire arena. Players should stand behind a spike to avoid the attack, or it will deal up to 80 damage. Prayer-draining attacks such as Smite, Corruption spells, and enchanted sapphire bolts will drain the shield quicker.
The prayer shield has 75 health and Phantom Muspah will heal itself 50% of the damage inflicted on it. Use a crossbow with an enchanted sapphire bolt or enchanted sapphire dragon bolts as they have a 25% chance to activate their special attack effect against the prayer shield. It will revert to its ranged form when its prayer shield is removed and create a large number of spikes before attacking the player normally.
In this phase, there is a smaller delay between the magic and ranged attacks, so ready to switch prayers more often. The spikes will also emerge more often, every four attacks, and cover more tiles. It can cover the whole arena if you don’t kill Muspah on time and you would have to teleport out.
Strategy for this form: Use a crossbow and sapphire bolt (e) to attack the shielded Muspah. When it breaks free, attack it with ranged while praying against ranged. Often Move, as the spikes explained below will appear where you stand and other tiles.
If Muspah spawns in ranged form, it will trigger lightning clouds at 75% health, but if it spawns in melee form, it will trigger homing spikes at 75% health. It will always do a second special attack at 50% health.
The Phantom Muspah will teleport rapidly around the arena and spawn lightning clouds across the arena, capable of dealing up to 20 damage. Players can avoid them by standing on the tile shown below. You should not stand on this tile until the attack is performed. Muspah can be attacked during this phase and will always appear northeast when the attack is finished.
The Phantom Muspah will slam the ground and 2-4 spikes will be launched at the player. Players can stand behind the hardened spikes to avoid the homing spikes.
Each Phantom Muspah kill is worth 299K GP. With the recommended stats above, players with the twisted bow can kill the Phantom Muspah up to 20 times in one hour. This results in a profit of 5.6M GP per hour after the costs of supplies have been deducted.
