Risk Of Ruina

Risk of Ruina is a content pack focused on adding content from the games Lobotomy Corporation and Legend of Ruina, as well as other Project Moon works. It currently features 2 Survivors, 9 Items, and 1 Equipment. Additional survivors are planned, as well as items to compliment them.

However, if you are only interested in part of the content, there is a full config available. So if you miss the standalone versions of Red Mist or An Arbiter, feel free to enable or disable any part of the mod you'd like! All survivors are compatible with Standalone Ancient Scepter, and have had custom balance patches to work with the King Kombat Arena.

  • Hooked into stat recalculation later so that Red Mist wouldn't be able to get speed changes from other mods' items
  • Snapping on level up will only occur for players now, not monsters


  • Rewrote Red Mist's bonus damage calculations.
    • They should make more sense now in general, and be easier to change via config.
    • Also, they will show up in the damage stat tracker if you are using BetterUI, so now you can watch that number go up.
  • Red Mist no longer starts with 2 jumps.
  • Red Mist's EGO Buff damage increase is now based on her Base Damage, instead of total damage.
  • To offset the last change, by default, Red Mist's stacking damage buff is no longer cleared on EGO loss. This can be changed to the old method in config.
  • Temporarily disabled Moonlight Stone
    • manipulating buffs in RoR2 is a massive pain
  • Nerfed Arbiter's Trophy to be a 1% chance instead of 2%, it was activating way too much.


  • Fixed Red Mist/Arbiter mastery unlock requirements
  • Fixed Arbiter mastery unlock icon for real this time
  • So apparently Volume_Master isn't needed and I was balancing all my sounds at 20% volume so honestly that's pretty wild and I'm sorry to everyone's ears
    • That's fixed now.


  • Removed some leftover debug messages
  • Added a config option to make An Arbiter's primary less grating
  • Added a config option to disable non-standard shaders on Red Mist
  • Fixed missing Arbiter Mastery achievement icon
  • Removed unused ragdoll from An Arbiter
  • Moonlight stone will no longer effect Runald/Kjaro's cooldown


  • Fixed Moonlight stone's buff removal calculation (should no longer end up with negative buffs)
  • Moonlight stone will no longer remove Desperado stacks


  • Fixed an issue with Black Tea's model
  • Improved item icon resolution
  • Fixed an error with countering non-living objects
  • Removed the ability to counter self-damage


  • Initial release
