Mortal Shell 2 Faded Citadel Walkthrough

How to enter

Blue flames

Enemies standing in blue fire take reduced or no damage until you put the flame out. Same trick as the fire in front of the Gate of Infinity Beacon. Extinguish first, then fight. A chest behind one flame holds Summoning Stone.

  1. Extinguish, kill, move. Pull one enemy at a time if the room is stacked.
  2. Servants of the Scholar-Prince: two flame zones. Put both out.
  3. Tag Citadel Atrium after that fight.
  4. Solnir, the Gloom Seeker, sits between two flames. Turn those off before you commit. Reward: Solnir Shard.
  5. Isaac in the final sanctum. Shield rips at 50%. Leaping Lunge and Pin Cushion (downward rapier chain). Reward: Scholar's Wormstone for Clockwork Scythe. Isaac guide.

Silent Steps / Chamber of Becoming (Sariel) connects off this Mammon spine. Do not Send Ova until that Shell and both of her weapons are done if you care about 100%.
