Mt. Gelmir Dungeons

• Seethewater Cave
• Gelmir Hero’s Grave
• Volcano Cave

Seethewater Cave

• Unique Rewards:
  • Mushroom Head
  • Mushroom Body
  • Mushroom Arms
  • Mushroom Legs
  • Kindred of Rot’s Exultation

The Seethewater Cave is a poison-heavy dungeon with toxic enemies and hazardous waters. Bring Neutralizing Boluses or Flame, Cleanse Me to counteract poison buildup. Avoid rolling in the water to prevent prolonged status effects.

Take the southwest path to find the Mushroom Armor Set, guarded by humanoid enemies and a Giant Miranda Sprout. The main path leads to the Kindred of Rot Duo boss fight, where fire-based attacks are highly effective. Defeating them rewards the Kindred of Rot’s Exultation talisman.

Gelmir Hero’s Grave

• Unique Rewards:
  • Ringed Finger
  • Mantis Blade
  • Bloodhound Knight Set
  • Gelmir Knight Set
  • Bloodhound Knight Floh
  • Deathroot

Gelmir Hero’s Grave is another chariot-filled dungeon featuring lava hazards, hidden paths, and tough enemies. Skeletons will attack as you dodge chariots, so a good shield helps avoid mistakes. The Ringed Finger weapon is found past the lava, and the boss fight is against the Red Wolf of the Champion, with a Deathroot in a chest nearby.

After the boss, you can ride the chariot to crush the Cemetery Shade for a Mantis Blade, then jump down to fight a Bloodhound Knight and claim both the Bloodhound Knight and Gelmir Knight armor sets. A hidden hallway leads to a Stonesword Key, though escaping means tanking chariot damage. The dungeon loops back via fire traps and ambushes, where luring enemies into flames can make fights easier. Grab Gloveworts along the way before heading back to the entrance.

Volcano Cave

• Unique Rewards:
  • Coil Shield
  • Jar Cannon

Volcano Cave in Mt. Gelmir is a short dungeon filled with weak demi-humans and a few notable items. After grabbing the Golden Rune [6], jump down and clear out the enemies below, then proceed north through the tunnel. In the next room, enemies hide behind crates, so either pull them back or ambush them first. Loot the Coil Shield, then return to the lower level to defeat the Demi-Human Chieftain if you haven’t already. Then, continue east to face Demi-Human Queen Margot, who drops the Jar Cannon upon defeat.
