Solo Leveling: Arise

B-Rank Gate: Crimson Caverns Description: A volcanic network of tunnels and caverns with lava pools and sweltering heat. Monsters thrive in this environment. Inside: Fire elementals, lava imps, and armored magma trolls. Final Boss: Ignaros, Flame Troll King – a towering troll with molten armor and fire-based shockwaves. Gate Effect: Upon Ignaros's death, the lava cools and hardens, and the gate implodes, sealing the rift.

The caverns are adorned with glowing magma flows and jagged obsidian formations, casting an eerie red light. The air shimmers with heat, and the ground trembles occasionally from the volcanic activity beneath.
