On October 28 IMC Games rolled out a substantial update to celebrate the fourth anniversary of Tree of Savior M. The anniversary brings fresh dungeons, a unique weapon, themed furniture, and an accelerated experience gain for players starting out or coming back.

The "Companion Summon" event grants a total of 330 attempts to build a personal battle squad. Participants receive a limited‑edition commemorative costume, while a separate "Goddesses vs Demons" mode lets players pick a side and summon allies from the chosen faction, based on favorite characters. A brand‑new unique weapon also joins the arsenal.

Two special dungeons have been opened to test the new line‑ups: a Halloween‑styled event dungeon and a jubilee trial dungeon that requires both seasoned characters and newly summoned companions. New sweet‑themed furniture lets players decorate their space, and the event‑earned costume gives characters a distinctive look. The development team promises ongoing updates and stable service for the future.
