The short version
30-second read- Melee only works below about 980 HP. That is roughly 65%, so every trip needs a magic or ranged setup plus a melee switch.
- Below about 20% it only melees. It stops retreating there, so the last stretch of every kill is a pure melee race.
- Pick Open-stomach unless you want the pet. Take-eggs gives up the fang and kisten rolls for 1/1,502.4 pet odds instead of 1/3,500.
- Learn the fight during the cheap death window. Your reclamation fee is cut by 75% until five more kills, so bring full supplies while learning the screech and slam.
Maggot King at a Glance
The Maggot King is a solo, instanced boss in Vampyrium that you unlock by finishing The Blood Moon Rises. It has 1,500 hitpoints, opens with ranged and magic attacks, and only lets you melee it once it drops below roughly 980 HP (about 65%), so every trip needs a magic or ranged setup plus a melee switch. The drops people farm it for are the elder venator fang at 1/340, the crimson kisten at 1/520 and the Maggot marquess pet.
It came out with The Blood Moon Rises on 30 June 2026. The lair entrance is in the forest east of Sangvesti, near the Ruined Village. Your first few kills are about learning the screech and the bone-wall slam, because those two attacks cause almost every early death.

Getting There Efficiently
- 1
Drakan's medallion to Castle Drakan, then enter Vampyrium.
- 2
Run east toward Sangvesti.
- 3
Rescue the aranei scout south-east of Sangvesti for quick travel.
Kill the three sanguidae attacking it first.
- 4
Take the 64 Agility bush shortcut furthest from the scout; the nearer one is longer and often pulls an ancient feral vyre.
- 5
Build the bank chest in Sangvesti for proper trips:
70 Construction, a hammer and saw, 1 magic stone, 2 cupronickel bars, 2 adamantite bars and 4 ironwood planks.
Recommended Stats
| Skill | Level | Why |
|---|---|---|
| Ranged | 85+ | If you range the opening phases |
| Magic | 75+ | If you mage it. Fire Wave needs 75; Fire Surge needs 95 |
| Attack / Strength | 80+ / 85+ | The melee phase and the melee punish |
| Prayer / Defence | 74 / 70 | Rigour, which the wiki calls highly recommended |
| Construction | 70 | The bank chest in Sangvesti |
| Agility | 64 | Bush shortcuts in Sotfa Forest |
Maggot King Gear
It is weakest to heavy ranged, crush and fire spells. You need either a magic or a ranged setup for the opening and a melee switch for the slam phase, so most inventories carry two styles. The table lists the top picks from the wiki's strategy page for each slot.
| Slot | Magic | Ranged | Melee switch |
|---|---|---|---|
| Weapon | Twinflame staff or harmonised nightmare staff on fire spells; Tumeken's shadow | Zaryte crossbow, Armadyl crossbow, dragon hunter crossbow | Inquisitor's mace (4-tick punish only), scythe of vitur, soulreaper axe |
| Off-hand | Tome of fire | Twisted buckler | Avernic defender |
| Ammo | Rada's blessing 4 | Ruby dragon bolts (e) | Rada's blessing 4 |
| Head | Ancestral hat or virtus mask | Masori mask (f) | Inquisitor's great helm or torva full helm |
| Body | Ancestral robe top | Masori body (f) | Inquisitor's hauberk or torva platebody |
| Legs | Ancestral robe bottom | Masori chaps (f) | Inquisitor's plateskirt or torva platelegs |
| Neck | Elemental amulet or amulet of fire (fire spells), then occult necklace | Necklace of rupture or anguish | Amulet of rancour or torture |
| Cape | Imbued god cape | Dizana's quiver | Infernal cape |
| Hands | Confliction gauntlets or tormented bracelet | Zaryte vambraces | Ferocious gloves |
| Boots | Avernic treads | Avernic treads | Avernic treads or primordial boots |
| Ring | Magus ring | Venator ring | Ultor ring |
| Special attack | Eye of Ayak | Zaryte crossbow | Crimson kisten, Voidwaker, dragon claws |
On a Slayer task, a slayer helmet (i) replaces the head slot in all three setups. Cheaper picks from the same tables: a rune or dragon crossbow with elite void, Blue Moon or Ahrim's robes for magic, and Dharok's greataxe for punishes.
Fire magic is the strongest opener because of the burn. Each fire spell that lands adds 5 burn damage, the stacks build on each other, and every stack lowers its magic defence by 20. Twinflame and harmonised nightmare staffs build stacks faster than an autocast staff, and the wiki rates Fire Surge with a tome of fire and sunfire runes or searing pages above Tumeken's shadow, which gets none of the burn benefit. Once 5 stacks are up, an Eye of Ayak special that hits 30 or more usually strips its magic defence to almost nothing.
For the melee switch, pick damage specials over Defence drains. Drained Defence comes back after the screech, so an elder maul or dragon warhammer spec wears off, while the crimson kisten, Voidwaker or dragon claws keep their value.
Mechanics Phase by Phase
The fight loops through 4 to 8 ranged or magic attacks and then a screech. Below about 65% HP the bone-wall slam joins the loop. Below about 20% it stops retreating and only melees, so the last stretch is a pure melee race.
| Mechanic | What it does | What to do |
|---|---|---|
| Ranged and magic spit | Hits up to 46. Ranged spit poisons you starting at 8 and leaves poisonous bile on three tiles; magic spit leaves sticky bile on three tiles. | Pray the matching protection prayer, which blocks it fully, and step off the bile. A serpentine helm with anti-venom+ makes you immune to poisonous bile, and an inoculation bracelet covers sticky bile. |
| Screech | Hits 15-25 per tick if a protection prayer is on. Its Defence halves to 100 while it screeches, then carrion falls for up to 25 (smaller bits up to 10). After the first screech its attack speed goes up by 1 tick. | Turn protection prayers off before it starts. Use the halved Defence for a Zaryte crossbow special, and step off the shadows where carrion is about to land. |
| Ur-maggot larvae | From about 1,250 HP a larva launches with each screech; from about 299 HP it sends up to four at once. A landed larva eats carrion to heal the boss 1 HP and chips you for 3, rising by 1 each tick. | Hit each larva with standard ranged before it lands and it dies instantly. The first one spawns west, then they alternate west and east. A venator bow's bounces hit several at once. |
| Bone-wall slam | From about 980 HP it walks to the bone wall and slams a 3x4 area for up to 55 (35 with Protect from Melee) and throws three biles. Its magic defence rises from +150 to +400 during this. | Move to the far east or far west tile as it winds up, then switch to melee. |
| Melee punish | Attacking on the tick it extends its head gives that hit no delay, 50% more damage and better accuracy. With crush, its defence roll is cut by 85%. Only the first hit of a multi-hit weapon gets the bonus. | 4-tick weapons need a step-back; 5-tick weapons can move east or west without losing ticks. Punishes ignore weapon attack speed, so slow, heavy weapons like Dharok's greataxe or an elder maul are fine here. |
| Final phase | Below about 305 HP it stops retreating and only uses melee. | Ignore the screech from this point and finish it with melee. |
Loot: Open-Stomach vs Take-Eggs
When it dies you choose one option on the corpse. Open-stomach rolls the normal drop table. Take-eggs gives up that loot for a better pet chance: you get one of six maggot eggs, a supply drop, or nothing.
| Drop | Rate | Notes |
|---|---|---|
| Elder venator fang | 1/340 | Etch it at 84 Crafting with a chisel, then use it on a necklace of anguish to make a necklace of rupture. The fang is untradeable; the etched fang trades. |
| Crimson kisten | 1/520 | Tradeable two-handed crush weapon, 60 Attack and 85 Strength, 4-tick. Its Brutal Swing special costs 50% energy. |
| Maggot marquess (pet) | 1/3,500 | Better odds through Take-eggs |
| Any unique | 1/205.6 | Combined chance per Open-stomach kill |
| Brimstone key | 1/50 | Only on a Konar task |
| Elite clue scroll | 1/40 | 1/38 once you unlock the elite Combat Achievement rewards |
The common table is mostly noted resources: uncut rubies, runite, adamantite, mithril and gold ore, mort myre fungus, letvek, venator fangs and teeth, plus tarnished jewellery and weapons. Supply rolls give 2-4 stymphike tartare and a dull ancient medal, and the tartare restores prayer mid-trip.
| Egg | Chance per Take-eggs | Pet chance |
|---|---|---|
| Base | 300/1,500 | 1/3,000 |
| Sickly | 150/1,500 | 1/2,500 |
| Warm | 33/1,500 | 1/1,250 |
| Pulsating | 6/1,500 | 1/500 |
| Wriggling | 3/1,500 | 1/10 |
| Writhing | 1/1,500 | 1/2 |
Added together that is a 1/1,502.4 pet chance per Take-eggs kill, about 2.33 times the Open-stomach rate. Elite clues can still drop on egg kills. Only take eggs when the pet is the goal, because you give up the fang and kisten rolls on that kill.

Death Fees & Learning Window
Your reclamation fee is cut by 75% until you have five more kills, and Jagex applied that to every player regardless of kill count. Use that window to learn the screech and slam timing with full supplies, not to test how little food you can bring.
Optional Help

FAQ
Can I melee the whole fight?
No. Melee only works once it falls below about 980 HP (65%). Below about 305 HP it stops retreating and the rest of the kill is melee only.
What is the Maggot marquess?
The Maggot King's pet, a small copy of the boss. It is 1/3,500 from Open-stomach and 1/1,502.4 per Take-eggs kill. If you already have a follower out it goes to your inventory, and if that is full you claim it from Probita in East Ardougne.
Should I always take eggs?
Only if the pet is your goal. Open-stomach is where the elder venator fang, the crimson kisten and the resource loot come from.
Is the Maggot King a Slayer task?
Yes, as a boss task from Konar, Nieve or Duradel. There is no Slayer level requirement, each kill gives 3,675 Slayer XP, and on a Konar task it can drop brimstone keys at 1/50.
How hard is the Maggot King?
Its basic attacks are fully blocked by prayer, so the damage comes from mistakes: a protection prayer left on through the screech (15-25 per tick), standing in the slam (up to 55) and larvae you let land. The wiki recommends 85 Ranged or 75 Magic, 80 Attack, 85 Strength and Rigour before you start.

Final Takeaway
Finish The Blood Moon Rises, rescue the scout and build the bank chest, then learn the loop: pray the spit, prayer off for the screech, shoot the larvae, dodge the slam and punish. Choose Open-stomach for the fang and kisten, Take-eggs only for the pet, and leave the Combat Achievements until the kills are routine.
