A new update from the Tree of Savior team talks about the use of language pack files that can be updated on the fly while playing the game. Each term or phrase is identified with a unique key. Once this is edited, it will be updated real time in the game. Translated texts will also be shared via OTC repository where fans can see the development of the texts. Also important to note that English, Chinese, Japanese, Korean, Portuguese and Spanish are supported languages.
