IMC Games has transitioned international servers of the game to a free-to-play model. Now Tree of Savior can be played using Steam. As developers state in their official post, all DLC products will no longer be available for purchase.
Instead, the developers will be launching a series of different bundles on a to-be-announced date.
IMC also made some changes to the SEA servers. The SEA server Telsiai will temporarily become exclusive to players already on the server, meaning new users in the SEA region will need to start playing on Varena, the recently opened SEA server.
