This piece is presented as a GamesRadar+ guide titled "How to upgrade weapons in Beast of Reincarnation," intended to explain the game's weapon enhancement system for players. However, the text supplied for this article consists entirely of website styling code (CSS) rather than any actual article content, so no genuine guide information, game mechanics or instructions could be extracted.

As a result, no substantive details are available to summarise — no specifics on upgrade materials, currencies, mechanics or steps mentioned in the piece. To provide an accurate summary, the original article page would need to be accessed directly so the actual written guide can be reviewed.
