    B11F (D1/E1): This area requires a long journey with potential Amrita II use. Navigate a winding path with deadends, fighting B11F-B14F monsters and Muckdile FOEs.

    B7F: Follow a long, winding path with heavy poison damage. Reach a door leading to a large clearing with more poison tiles. Head West for a Medica IV, then North along the Western wall to find a Warp Point (7 squares North of the chest). Explore the corners of the clearing: NW for a Surcoat, NE for a Soma, SE for a Bravant II. The Alraune monster is also found here for a future quest.

    Continuing B14F: Return to Kupala's location. Head South and East for a Medica III. Use lilypads: South to a 1x3 platform, West for an Ice Mist, back East, then East again (watch for Killclaw). Head East then North to a 4x3 platform with 800en and a Hamao (Muckdile FOE present). Return South, then West, then West again to a platform with two lilypads. The Northern one returns to Kupala's area; the Southern one leads to the final 3x3 platform with stairs to B15F.
  11. 11
    B15F: From the stairs, go North through a door for a Scale Boot and Blaze Oil. Head East to a warning before a door. Return to town to rest and prepare for the boss fight.
  12. 12
    Boss Fight - Cotrangl: Enter the room and go East. Kupala summons Cotrangl.
  13. 13
    B16F Exploration: After defeating Cotrangl, take the lilypad East to B16F. New monsters include Goldeer, Flamerat (fire resistant), Mantis (Silver Eye drop if killed in one round), Sabremaw, and Sickwood (FOE, can poison party). Be aware of moving sand mechanics.
Tips
  • If you opened the Gem Staff before collecting Violet Crystals, consider if you need to buy more.
  • For B11F, bring Amrita II if possible due to the long journey.
  • For B7F, ensure your Medic has ample TP and bring TP recovery items/methods due to poison damage.
  • For the Cotrangl boss fight, aim for Level 40+, ideally 45-48 or higher. Use Defender and Immunize.
  • To obtain the Ice Spine (for the best bow), land the killing blow on Cotrangl with a non-Fire attack.
  • Defeating Cotrangl completes the Radha Hall quest, rewarding 8000en.
