Monster Soul

Season 14 Monster Soul — buy a converter, hunt an area's monster until the souls are full and pick your reward.

Monster Soul arrived on October 8, 2026, from MU's Season 14. It is a weekly hunt: you activate a Monster Soul Converter in an area, hunt that area's monster until you gather the souls, and trade them for a reward.

Open it from the Progress → Monster Soul menu, or right-click a converter in your bag.

How it works#

  1. Buy the converter on the Monster Soul page. You get 3 purchases per week per character. The week resets on Thursday at 10:30 (Brasília time).
    • Level 1: 200,000 zen
    • Level 2: 500,000 zen
    • Level 3: 1,000,000 zen
  2. Activate it in an area of the converter's level. The converter is spent. You can only activate areas on maps you can already enter, and you have one active converter at a time.
  3. Hunt the area's monster on its map. Each kill has a 45% chance to yield a soul. The soul goes to whoever landed the last hit.
  4. When the goal is full, pick the reward category. The reward arrives at Gremory.

Changed your mind? Abandon ends the collection, but the spent converter does not come back.

Rewards#

  • 400 Ruud (the Ruud Shop currency)
  • plus one draw: another converter of the same level (57% to 72%, depending on the level) or a Jewel of Bless.
