Risk of Rain 2 Randomizer
A randomizer mod for Risk of Rain 2!
It is highly recommended to take a look over the mod settings before starting a run. By default most randomizers are enabled, which can be a bit much to take in at once.
Current features:
- Multiplayer Compatible. Every player needs to have the mod.
- Compatibile with Risk of Options for easy configuration in-game.
- Stage Randomizer: Swaps every stage for a random playable map.
- Each stage is paired one-to-one with a replacement stage (for example bazaar will always be randomized to the same stage during the course of a run)
- Boss Randomizer: Randomizes the character types of bosses. Currently Mithrix, Voidling, Aurelionite, Twisted Scavengers and Alloy Worship Unit are implemented.
- Status Effect Randomizer: Randomizes all buffs/debuffs applied to characters.
- Survivor Starting Animation Randomizer: Randomizes the first stage spawn animation of all survivors.

- Projectile Randomizer: Randomizes projectiles. Please note that certain attacks are also not technically projectiles (even if they have travel time), most notably almost all of Huntress' attacks, meaning they are not affected by this randomizer.
- 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.
