→

Tekton

Melee room: crush weapon. The Elder maul special lowers his defence even if it misses. Inquisitor's helps land specials.

→

Vasa, Vespula and Shamans

Ranged on Vasa, Vespula, Shamans, Mystics and the mage Vanguard (Tbow or a crossbow with ruby bolts). Vasa's crystals only with stab; Vespula's portal also with fire spells.

⚠→

Ice demon

Chop saplings (54 kindling solo) and light the 4 braziers. Once it comes out, Protect from Missiles so it only throws snowballs. Only demonbane (+15%) and fire spells (+150%) deal proper damage; everything else 67% less.

→

Crabs, tightrope and chests

Crabs: Protect from Melee, stun them with a hammer and bounce the white orb until all 4 crystals turn white (red melee, blue magic, green ranged). Tightrope: kill the mages first and cross for the keystone. Thieving: chests with grubs; 3 are poisoned.

⚠→🔄

Olm: spheres

Red sphere = Protect from Melee, green = Missiles, purple = Magic; pray before it lands or lose 50% of your HP and your prayer. Head: ranged only; right hand: magic; left hand: melee (66% less with any other style).

⚠→🚫

Olm: powers and specials

Acid: stay off the pools. Flame: douse the wall with a water spell or Humidify. Crystal: falling crystals and bombs (get 4 tiles away). Crystal Burst: step off the crystal. Lightning: do not cross the bolt. Teleport: everyone on the same tile (or the marked tile solo).

⚠→🚫

Olm: hands

Kill the mage hand first: if the melee hand takes 5% of its HP within 8 ticks it clenches for 30 s. Penultimate phase: leave both hands at ~75 HP and drop them together, melee hand first (it heals 2 attacks after the teleport).

→🔄

Olm: final head

Head only, with ranged. Crystals fall constantly and it spits 2 blue projectiles: stand on those tiles within 6 s or it drains your HP and heals 5x that.

1. Reach Mount Quidamortem (Lovakengj minecart, fairy ring BLS or Xeric's Honour after the Ancient tablet). No requirements; 75 Herblore for Overload, 78 for the (+) recovery potions and 90 for Overload+.
2. In the resource rooms farm Golpar, Buchu and Noxifer, fill gourds at the geyser and brew Overload, Xeric's aid and Prayer enhance. Store gear in storage units (Construction 30).
3. Clear both floors using each room's style (crush on Tekton, stab on crystals, fire/demonbane on Ice demon).
4. At Olm: 1 overload, 1 prayer enhance, 2-3 restores and 6-7 brews each; stamina solo. Mage hand, then melee hand, every phase.
5. Penultimate phase both hands at once; last phase ranged on the head and stand on the blue projectiles. Open the chest.
