"Dwarven pipes can transport more than just steam. Water, oil, air, even molten rock in some cases. That's the beauty of Dwemer designs. Their versatility means they can be repurposed for any use. It doesn't take a genius to see that, but it helps." —Raynor Vanos
Stone Garden

Dungeon Mechanics[edit]

Werewolf Behemoth[edit]

Werewolf Behemoth transformation

This dungeon involves a mechanic whereby players can transform into Werewolf Behemoths. This effect lasts for several seconds and causes your character to become much more powerful. Your usual skill bars are locked while transformed and replaced by a unique set of skills: Vicious Bite, Rampage, Bonecrusher, Thunderous Stomp, Bestial Frenzy, and Lead The Pack.

For more information, see this page.

Alchemy Buffs[edit]

Alchemy Table when usable

Throughout the dungeon, you may discover three locked side rooms containing Alchemy Equipment guarded by a Bloodknight. You can enhance your Behemoth form for the duration of the dungeon by performing alchemical experiments at these tables, using the Gloomspore Agaric mushrooms that can be harvested throughout Stone Garden. A player with the Laboratory Use passive can improve on the mixtures and unlock more powerful buffs.

For information on the three alchemical experiment tables, see this page.

Exarch Kraglen[edit]

  • Slaughter: Exarch Kraglen winds up and eviscerates you with his claws. Deals major physical damage and hits twice. Needs to be blocked or dodged. Will one-shot most non-tanks.
  • Blood Rage: The most crucial mechanic to pay attention to. Kraglen will roar at you, knocking you down if you're too close to him. This drains and reduces your resources if you fail to interrupt it. Players fighting from a distance can use Crushing Shock to interrupt this ability to help out the tank.
  • Charge: Kraglen glows red and charges at a player, dealing major physical damage. This ability needs to be blocked, and is similar to Xal-Nur the Slaver's charge in the Ruins of Mazzatun in that regard.
  • Fault Line: Kraglen stomps. On veteran, if you're in range when he stomps, you may be killed in one hit. Fissures crack open the ground in a winding line towards a player. Deals moderate damage. If you stand in the AoEs, you will be stunned.
