City of Steam Wikibase™ Zones

Each Boss Raid Challenge dungeon that you complete will grant rewards in addition to any items you find within it.

• Normal mode: Transmuter Orbs, Mastery Points, Expertise Points, Rare Materials Boxes, EXP
• Vanquish mode: EXP, Shillings, Mastery Points, Expertise Points. Note that EXP is higher than Normal mode to compensate for the loss of kill EXP that you do not get in this mode.
• Heroic mode: Rare Materials Boxes, Orange Material, Shillings

The amounts will vary by level and mode.

The Sunken Fragments: The Myth Hub is in the room you zone into from The Sunken Ruins.

Sunken Ruins Boss Raid (Heroic Mode)

There are some major differences from the Vanquisher mode, here. First, the map is totally different, and so are the mobs. They are still level 29, though, so there is some good news.

• Skeleton Necromagus
• Triggershade Imp
• Tombcrawler
• Skeleton Headsman
• Boss: Sarcophage

While it appears that you can bypass a number of mobs to the right at the first split, we recommend you not try. Take the right first, then the left. If you do not they all tend to add in an unruly mob.

Likewise, if you try to avoid half the mobs just before the boss, the pack you avoided will add on the Boss fight.
