Hello everyone!

Today is the release of Early Access major version 0.3

This update has many exciting changes, vastly improving player agency, including a complete revamp to item upgrades, build diversity, as well as many QoL improvements.


  • Complete redo of Implants. Implants no longer drop as items, but are configured via the Item menu. This system is outlined in detail below.
  • Many new Unique Modifiers (Keystones) for each item. Every item now has at least 2 Unique Modifiers available to them.
  • New Buff Bar, showing active effects on your character.
  • New currency drops, used for upgrading your items.
  • Changes to the way armor functions (better defense with higher investment)
  • Many minor UI improvements
  • Many tweaks to player power curves, player experience curves, item drop curves.
  • Removed the infinite stacking player damage buff.
  • Reworked the power levels and costs of almost all mutations.
  • Much more I’m forgetting.

Armor Changes
**OLD**: Armor provides 50% less damage taken per 18 armor, capped at **87.5% reduced damage taken**. This is reached at 54 armor. **NEW**: Armor provides 50% less damage taken per 100 armor, capped at **97% reduced damage taken**. This is reached at 500 armor.


The following is a list of the current keystones available as mods.
