Official FAQ
Q: How do I reset my attributes / Gear points / Technique points?
Players have three options when it comes to point resets: purchase the respective reset from the developer products menu for Robux; trade in-game items for developer products from other players; or exchange Heian Rating points for purple caches at the Shibuya black market.
Q: How do I wipe?
Cursed Gear is not a permadeath game, and there is no option to wipe characters at the moment. Players can freely change weapons, Gears, and Cursed Techniques at their convenience, so there is currently no need for wiping.

What you can change
Even without wiping, you have flexibility. Gears can be swapped during expeditions for Shine. Cursed Techniques can be replaced by collecting Technique Shards and forming a new crystal. Attributes, gear points, and technique points all have reset options via developer products or in-game trading.
