Another Slice of H.A.M.

Speak to Ur-tag upstairs, or Ambassador Alvijar, in the northern part of Dorgesh-Kaan. They are building a rail link to Keldagrim.

Go to the station south-west of the city — do not take the first staircase down — and through the doorway marked with a transport sign.

Walk south along the tracks and talk to Tegdak for a trowel and specimen brush, then dig up the artefacts on the unfinished line.

Bank and equip Ranged or Magic before continuing. There is no bank between here and the fight.

Melee cannot be used on the H.A.M. attackers. Knives and darts only work on long range, so bring a proper bow or a staff.

Zanik follows you from here. Dismiss any pet or follower first, and do not teleport — either loses her.

If you lose her, go back to the railway station tunnel and ask her to follow again, then have Oldak teleport you a second time.

After the cutscene, two H.A.M. members attack the goblins. Head south round the back of the buildings on the west side, staying out of range.

Climb the tower ladder and kill the level 30 H.A.M. Mage and Archer with Magic or Ranged.

A bronze crossbow and 50 bolts spawn by the ladder if you need them. They do not respawn, but closing and reopening the quest instance restores the bolts.

Sigmund plans to kill Zanik on the tracks and start a war. The Dorgesh-Kaan staircase is closed, so go to the Lumbridge Swamp Caves entrance instead.

Talk to Sergeant Slimetoes and Sergeant Mossfists near the cave entrance — bring your light source.

Fight Sigmund at level 64. He switches on the protection prayer matching whatever you hit him with, so use the ancient mace special attack to strip his prayers, then finish him however you like.

Do not use the special in the first moments of the fight. Used too early it can fail to register and the prayer drain never applies.

Untie Zanik after he teleports away and watch the final cutscene. Riding the train to Keldagrim afterwards is a hard Lumbridge & Draynor Diary task.
