Risk of Rain 2 Randomizer

A randomizer mod for Risk of Rain 2!

It is highly recommended to take a look over the mod config before starting a run. By default almost all randomizers are enabled, which is utter chaos, which you may or may not want.

Because I'm such a narcissist, this mod has a dedicated Discord Server! Join if you're into that.

Current Features:

  • Multiplayer Compatible. Every player needs to have the mod.
  • Compatibile with Risk of Options for easy configuration in-game.
  • Consistent Randomness: The way things are randomized is consistent throughout a run. A certain randomized replacement (item, summon, buff, etc.) will always be the same until the run ends.

Current Randomizers:

  • Stage Randomizer: Swaps every stage for a random playable map.
  • Boss Randomizer: Randomizes the character types of bosses. Currently includes Mithrix, Voidling, Aurelionite, Twisted Scavengers, Alloy Worship Unit and Teleporter Bosses.
  • Item Randomizer: Randomizes items and equipments
  • Item Tier Randomizer: Randomizes which tier all items are in
  • Status Effect Randomizer: Randomizes all buffs/debuffs applied to characters.
  • Survivor Starting Animation Randomizer: Randomizes the first stage spawn animation of all survivors. randomspawnpod
  • Projectile Randomizer: Randomizes projectiles.
  • Summon Randomizer: Randomizes summoned characters.
    • Buying drones
    • Squid Polyp
    • Engineer Turrets
    • Soul Wisp
    • Malachite Urchin
    • Healing Core
    • Void Infestors
    • Beetle Guard, both from Queens Gland and spawned by the Beetle Queen itself.
    • Quiet Probe and Delighted Probe spawned from the Solus Probes item
    • Strike Drone spawned from The back-up equipment
    • Col. Droneman spawned from Spare Drone Parts
    • Shopkeeper Newt
    • Solus Probes spawned by Solus Control Unit and Alloy Worship Unit
    • Heretic
    • Alpha Construct spawned by Defense Nucleus
  • Effect Randomizer: Randomizes visual effects.
  • Weak Point Randomizer: Randomizes which hitboxes are considered weak points by Railgunner's scoped shot. The number of weak points per character remain the same.

    • Added Alpha Construct spawned by Defense Nucleus to summon randomizer.
