Death to the Dorgeshuun

You need two full seven-piece sets of H.A.M. robes. Drop rates are much better during the quest itself, so start it before farming them.

Take a lantern, not a candle. Open flames set off gas in these caves and need a tinderbox to relight.

You end up in the jail. Talk to Jimmy the Chisel, who explains Sigmund took Zanik outside, then pick the lock.

If you leave before talking to him, Johanhus will tell you the same thing.

Zanik is dead outside. Investigate her — her mark is glowing — and carry her body to Juna in the Chasm of Tears.

Juna asks for 20 tears collected with Zanik's bowl. A games necklace teleports you close.

This gives no experience and does not use up your weekly Tears of Guthix visit.

If you die carrying her, she respawns at the H.A.M. hideout rather than being lost.

Zanik overheard a plan to flood the swamp caves using a drill at the Lumbridge water wheel.

Get your combat gear and take Zanik to the chicken farm north of Lumbridge Castle across the river. Teleporting leaves her behind — retrieve her from the cellar, or log out and in if she does not appear.

Wearing the full H.A.M. outfit and with no weapon or shield equipped, search one of the empty southern crates so Zanik can hide inside, pick it up and go down the trapdoor.

It must be an empty crate, not one holding machine parts, and your hands must be free to carry it.

In the west room, Sigmund at level 50 appears with three level 22 guards.

He mirrors whatever style you attack with, so kill the henchmen first. The crates make a safespot for Magic or a halberd.

Once they are down Zanik shoots him and he switches to Protect from Missiles — so finish him with melee or magic. He escapes at 1 hitpoint with a ring of life.

Smash the drilling machine and leave through the southern tunnel.
