Swamp of Destruction

On the orders of the MU Empire, explorers studied the Swamp of Peace that Mallone had found. With the heroes' help they searched its four islands and confirmed Medusa and new creatures there. They also found signs of a lost civilization, such as statues, a square and an altar on the western island and a cemetery on the southern one, but not a single person.

The explorers rebuilt a broken magic circle from its scattered pieces into a statue and had wizards activate it. Instead of a normal portal it threw up an eerie purple pillar of light and sparks. The heroes stepped in first and found themselves on a huge, bleak, dark island full of the same monsters as the Swamp of Peace, now crackling with energy. Long ago the circle had sent monsters from here to the swamp, growing weaker the farther they went, until their victims smashed it. This island is the Swamp of Destruction.

The Swamp of Destruction later got an Elite Zone, marked by an Elite Zone Flag, which replaced the one in the Kardamahal Underground Temple. Its Elite monsters (level 1,010) applied an element-based Elite Debuff on every hit, shared boss immunities such as against Punish, and could be countered with a Guardian's Elite resistance option.

The Swamp of Destruction was the centrepiece of the second Season 20-2 update in February 2026. The same patch added the 8th mastery earring, the Earring of Frost (see mastery items), and adjusted the EXP curve so characters level faster.
