Slayer Bosses

The Slayer bosses are the high-Slayer lairs every OSRS player grinds for their best-in-slot

pieces, kept mechanically faithful. Four of them are gated by your Slayer level — Kraken 87,

Cerberus 91, the Thermonuclear Smoke Devil 93 and the Alchemical Hydra

95: the portal refuses the teleport and the game refuses the attack until you have it.

Kraken (87 Slayer)

Portal → Kraken lands you at the boss pool in Kraken Cove. Four tentacle whirlpools ring

the big one — Disturb each tentacle to raise it (they spit for a little damage), then Disturb

the Kraken's whirlpool. The Kraken casts a magic bolt (max 28) — Protect from Magic and a

trident or the best spell you have. It never leaves its pool. When it dies the tentacles sink

and the pools reset a few seconds later.

Uniques: Trident of the seas (1/512), Kraken tentacle (1/400), Jar of dirt (1/1000), Pet

kraken (1/1000).

Cerberus (91 Slayer)

Portal → Cerberus lands by the west lair; there are three lairs in Taverley Dungeon's

depths. Cerberus melees up close (max 23) and fires magic and ranged (max 23) at range,

with three signature moves:

• Triple attack — magic, then ranged, then melee two ticks apart. Switch prayers in order.
• Summoned souls (below 400 HP) — three ghosts walk in and each fires its own style. Pray the matching overhead: blocked attacks cost 30 prayer (15 with a spectral spirit shield), unblocked ones deal 30 through everything.
• Lava (below 200 HP) — three pools, one on your tile. Standing in one hurts every two ticks; the final flare hurts more. Step off.

Uniques: Primordial, Pegasian and Eternal crystals (1/512 each), Smouldering stone (1/512),

Jar of souls (1/1000), Hellpuppy (1/1000).

Thermonuclear Smoke Devil (93 Slayer)

Portal → Thermonuclear Smoke Devil, deep in the smoke devil dungeon (multi-way). Wear a

facemask or Slayer helmet — without one every attack is 18 unblockable smoke damage. With

one it spits a fast ranged attack (2 ticks, max 8); Protect from Missiles.

Uniques: Occult necklace (1/350), Smoke battlestaff (1/512), Dragon chainbody (1/1000), Pet

smoke devil (1/1000).

Skotizo (dark totem)

Portal → Skotizo lands at the Catacombs of Kourend altar. Bring a dark totem (Skotizo

drops totems himself, and pieces come from the catacombs) and use the altar's Teleport option —

or ::skotizo — to be dragged into a private instance of his chamber. He melees (max 38)

and casts (max 38). Four altars around the room wake on their own; every awakened altar

hardens him — kill them (they're attackable) to put them back to sleep. When he dies you are

returned to the catacombs.

Uniques: Dark claw (1/25), Skotos pet (1/65), Uncut onyx (1/128), Jar of darkness (1/500);

always a hard clue and 1–3 ancient shards.

Demonic Gorillas

Portal → Demonic Gorillas drops you in the Crash Site Cavern (multi-way) with a dozen

gorillas. Each fights with one style at a time — melee when it can reach you, otherwise

ranged (green) or magic (purple), max 31 — and switches style after three misses or

three prayed hits. Every 50 damage it takes it switches its own prayer to block the style you

just used, so bring two styles. Its boulder lands on your tile every so often for a third

of your health — move when it raises its arms.

Uniques: Zenyte shard (1/300), Ballista limbs, Ballista spring, Heavy frame and Monkey tail

(1/500 each).

Karuulm Slayer Dungeon

Portal → Slayer → Karuulm Slayer Dungeon lands you in the lift hall under Mount Karuulm.

The whole dungeon is open: sulphur lizards (44 Slayer) by the entrance, wyrms (62) in

the western halls, drakes (84) and hydras (95) further north — the OSRS Slayer levels

apply to each, and every kill pays Slayer xp. No boots of stone are needed here.

All uniques and pets are Collection Log entries; every boss counts toward ::kc.
