OSRS Basilisk Knights Guide: 60 Slayer, Location & Jaw Drop

Overview: Basilisk Knights at a Glance

Basilisk Knights are level 204 Slayer monsters in Jormungand's Prison, under the Island of Stone. You need 60 Slayer, The Fremennik Exiles completed and a mirror shield or V's shield equipped; without the shield they hit hard and drain your stats. A Slayer task is optional, but the basilisk jaw drops five times as often on a basilisk task.

To get there, talk to Haskell on Rellekka's westernmost dock, walk north into the prison, then head south-west to the room where you fought the Jormungand. The jaw they drop turns a helm of neitiznot into the Neitiznot faceguard.

Pray Protect from Magic the whole time and tank their slash attack, which tops out at 20. Their weak spots are crush and heavy ranged ammunition, both at -15 defence, so a crush weapon or a crossbow is the usual pick.

Access Requirements

• 60 Slayer to damage them. Each kill is 300 Slayer XP.
• The Fremennik Exiles, the quest that ends in Jormungand's Prison. Our Fremennik Exiles guide lists its requirements.
• A mirror shield or V's shield in your shield slot for the whole fight.
• Optional: a basilisk task. Vannaka, Chaeldar and Mortimer assign basilisks as normal; Konar, Nieve and Duradel only after you buy Basilocked for 80 Slayer points.

Off task you can still kill them, but the jaw is five times rarer, so most players save their kills for a basilisk task.

Location and How to Get There

Basilisk Knights are in Jormungand's Prison beneath the Island of Stone. Reach Rellekka's north-western docks with Fremennik sea boots, a Lunar Isle teleport or house portal, Jarvald's boat from Waterbirth Island, or an enchanted lyre, then talk to Haskell on the westernmost dock.

On the island, walk north to the prison entrance, then south-west to the Jormungand's old room. The prison also holds regular basilisks and dagannoth. You cannot use a cannon on the basilisks, and thralls do not work in their single-way area.

Recommended Combat Stats and Gear

• Melee is usually the fastest. The wiki's top setup uses an Inquisitor's mace with Voidwaker as the special, and cheap fast crush weapons can beat pricier ones at some levels.
• Ranged is the safer option. Crossbows are the norm: ruby dragon bolts (e) on a knight at full health, dragonstone dragon bolts (e) once it is below roughly 180 HP.
• Magic is comparable to ranged for ironmen, helped by the 40% earth weakness.
• Every setup uses the mirror shield or V's shield, so there is no room for a defender or other off-hand.

Inventory and Supplies

• Prayer potions or super restores for Protect from Magic.
• Super combat potions for melee, or ranging potions.
• High-healing food. Every kill drops big bones, and casting Bones to Peaches turns them into peaches that heal 8 each.
• Telekinetic Grab and High Level Alchemy runes, ideally in a divine rune pouch.
• Vengeance or Death Charge in place of thralls, which cannot be used here.
• A house teleport, or a Construction or Crafting cape.

Mechanics: Attack Styles, Max Hits and Immunities

Where Basilisk Knights Sits in Progression

Within the Slayer boss group, the fights below Basilisk Knights are Kraken and Thermonuclear Smoke Devil. Above it sit Araxxor and Abyssal Sire.

Fight Strategy: Shield On, Pray Magic, Hit Crush

1. 1

   Equip the mirror shield or V's shield before you walk into the room.

2. 2

   Turn on Protect from Magic and leave it on.

   In melee you tank their slash hits, which max at 20.

3. 3

   With ranged, stand where they cannot reach you in melee.

   They cannot pass the one-tile doorway near the Jormungand's room, so from there they can only cast, and your prayer blocks that.

4. 4

   Hit crush or use heavy ammunition.

   Both sit at -15 defence, against +30 for stab, slash and magic.

5. 5

   Keep the big bones and turn them into peaches when food runs low.

Their attack speed copies yours when you stand outside melee range, down to a 4-tick floor, so a fast ranged weapon also makes them attack faster. Behind the doorway that only changes how often they cast at your prayer.

Drops and What Basilisk Knights Is Worth

The basilisk jaw is the reason to be here. Talk to Olaf the Bard with the jaw in your inventory, then combine it with a helm of neitiznot to make the Neitiznot faceguard. It needs 70 Defence and The Fremennik Exiles to wear, has double the helm's strength bonus, and can be turned back into the helm and jaw at any time.

The jaw is five times more common on a basilisk task than off task. The rest of the table is steady: hard clue scrolls, mystic hat (light), basilisk heads, long bones and big bones every kill. With Bigger and Badder unlocked, a Basilisk Sentinel superior can also spawn while you are on task.

Combat Achievements

Basilisk Knights have one Combat Achievement: Reflecting on This Encounter (elite, 4 points). One kill completes it.

Ironman Notes

Vannaka, Chaeldar and Mortimer assign basilisks as normal; Konar, Nieve and Duradel need Basilocked (80 Slayer points). Each knight is 300 Slayer XP.

Mains can buy the jaw on the Grand Exchange. An ironman has to get it himself, which makes Basilocked worth buying early: every basilisk task from a high-level master becomes a chance at the jaw at the better on-task rate.

Common Mistakes and Death Causes

• Forgetting the mirror shield or V's shield, then taking heavy damage and stat drain.
• Praying Protect from Melee. Their magic is what you want blocked; the slash hits only reach 20.
• Trying to cannon or use thralls in the basilisk area. Neither works.
• Using stab or slash weapons when crush hits a -15 defence.
• Farming off task and expecting the jaw at the on-task rate.
