The melee punish is a mechanic in the Doom of Mokhaiotl fight. When the boss raises Protect from Missiles and Magic and charges a beam, usually before 75% health, the player must hit it with a melee weapon to break the laser. The hit deals bonus damage per hit splat based on the player's total strength bonus12.
Gnomonkey's advice on the weapon changed over a few weeks in 2025. On 25 July he said not to spend spec on the punish and to use a Scythe; on 31 July he changed his opinion, saying that from a green tile the Chally is better, and by 9 August he recommended bringing a Chally even to players who own a Scythe and no Zaryte crossbow785.
Mechanics
The bonus damage per hit splat equals total strength bonus divided by five, and Gnomonkey says players can hit well over 100 during this phase3. Piety, combat potions and a Void melee helm do not affect strength bonus, which is the only thing that affects the bonus damage, so switching to boost the normal swing is not worth it; the goal is always to maximise strength bonus9.
The bonus hit splats do not trigger Blood fury or special effects such as the Saradomin godsword or Bandos godsword drains; the bonus damage is only damage to the boss10.
If the beam charges fully, it fully heals the boss and sends a death laser that starts with hits in the 60s and rises to 99 at a certain delve6. A player on attack cooldown can still do the punish, as with Zebak jugs, so there is never a time when a player cannot punish after shooting11.
On delves 2 to 8, finishing the boss with a melee punish while it is at low health shoots out holy water that clears acid and restores about 15 prayer points and around 50 health. Developers made this not work on delve 9 or higher12. On delve 3 the shield phase's bonus hit splat can break an in-progress punish and disrupt boulder prayer timing; Gnomonkey thought this might be hotfixed13.
Weapons
Gnomonkey says to judge punish weapons by average hit rather than DPS, because a fight has only one or two punishes4.
| Weapon | Figures | Notes |
|---|---|---|
| Scythe of Vitur | About 28 DPS in his calcs; max 115, five tick, three hit splats; averages about 70144 | Needs no spec4 |
| Chally | About 26 DPS; max 156, seven tick; averages about 92144 | Costs 30% spec; can hit from out of range745 |
| Nally | Averages about 5015 | High strength bonus for a two-hander; can hit from out of range; he would not bring it over a Chally15 |
| Claws | About 50 strength bonus against about 120 for a Chally16 | Only decent; Burning claws' extra 5% against demons is negligible16 |
| Scythe-style "boppers" | Hit the same as a Nally17 | Vastly better than anything else without a Scythe; double hit can one-shot the two-health grubs, replacing a Demon bane weapon and saving a slot1817 |
Without a Scythe he rates boppers first and Burning claws probably second18. He says claws are better than a Scythe, though Gearscape did not show the correct claw damage at the time19. Ralos, Warhammer and Elder maul are awful here and worse than simply shooting the boss, because about 70% of the fight the player has 100% accuracy16.
Scythe versus Chally
On paper the Scythe has better DPS, being five tick against seven. Gnomonkey says lost ticks do not matter on the punish, since the boss does not attack the player and there are no grubs yet20.
On 25 July he said the Chally spec is not worth it, because it spends 30% spec energy on a slow double hit splat while swinging a Scythe uses none, and the energy is better spent on Dragon knives during the car phase. He advised spending spec on the car phase unless opening with a Zaryte crossbow to leave the initial phase quickly71921. On 31 July he changed this: the Chally gives the most damage on the punish for 30% spec, and he used to say always use a Scythe, but from a green tile the Chally is better8.
His Chally method is to push the boss into the shield phase with a big punish, regain spec from Death Charge off the grubs, and continue. This leaves the boss at similar health to a Zaryte crossbow opening while spending 30% spec instead of 72 to 75%22. A Scythe from that position would have poisoned him, hurt a lot and done less damage than the Chally22.
By 9 August he recommended a Chally even for players with a Scythe and no Zaryte crossbow, because specs need to be used up and the Chally can hit the boss from out of range, which helps when there is a lot of acid5.
Chally punish technique
Bring the boss to around 84% health, a sweet spot, and stop shooting once a big hit near 90% has landed. When the prayer shield goes up, click a green tile and then the boss; the player runs straight to the boss's corner, where there is the best chance of no acid23. A halberd used for extra range in longer delves must also start the punish from a green tile23.
Strength bonus and switches
Gnomonkey uses a two-way switch for the punish. He considers a large multi-switch setup (up to six-way) not worth the brew slots even though it could hit around 180, because the damage only pushes the player into the shield phase and does not make the car phase safer24.
He brings either ferocious gloves (14 strength) or a Blood fury, aiming for a total strength bonus that ends on a multiple of five, such as 110, 115 or 120. If the gloves leave him short of a threshold, for example at 114, he brings the Blood fury for the healing25.
