Friendly reminder that I'm not a dev for this game, and it's not really the place to ask about potential bugs. Risk of Rain 2 has its own official discord, which I recommend everyone joins. They have channels you can direct questions to where actual devs and people with game knowledge will assist you.

There will be spoilers in this guide!

Please be sure to leave a thumbs up on this guide if it helps you out, so other people can see that you recommend it and can benefit as well!

If playing multiplayer, I believe you will encounter all items that the host has unlocked, regardless of whether or not you have unlocked them yourself. You must still unlock the items via their requirements to find them in your own singleplayer games, or when you host.

Items are listed in order, left to right, top to bottom, as they appear in the in-game logbook. All items that have unlock requirements have the unlock condition listed beneath them.

Essence of Heresy

• Replaces your Special Skill (Slot 4) with Ruin.
  
• Dealing damage adds stacks of Ruin for 10 (+10 per stack) seconds. Activating the skill detonates all Ruin stacks at unlimited range, dealing 300% damage plus 120% damage per stack of Ruin. Recharges after 8 (+8 per stack) seconds.
  
• Hold all 4 Heresy items to transform your character into the Heretic.

Beads of Fealty

• When you obliterate yourself at the Obelisk while holding one of these items, you will be teleported to a new "final boss" level. This level holds a Scavenger boss with several upgrades over the normal one, and when you defeat this enemy it will drop 10 lunar coins. Afterwards, the game will fade to black and "end".
  
• Stacking this item does nothing. Only one person in a multiplayer game must have this item for it to work, but I personally have not tested whether or not the one person holding the item has to be the one to activate the Obelisk or not.

Purity

• All skill cooldowns are reduced by 2s (+1s per stack). All random effects are rolled +1 (+1 per stack) times for an unfavorable outcome.
  
• Due to the counteracting luck-based effects, Purity and 57 Leaf Clover cancel each other out, leading to no increase or decrease in luck.

This is a section created specially for any items that have been encountered but have no logbook entries. There will likely be missing data in several parts on these items, as they do not appear in the logbook. Each of these items drop from killing elites of the same type.

The common theory is that these "Aspect" items are a more permanent version of what happens when you kill certain elites (lightning, fire, ice) while using the Wake of Vultures legendary (red) tier item.

UPDATE: Aspect items are a pain to collect data on, and they don't show up in the logbook like the rest of the items. I'm going to go ahead and just call this section defunct for now until I can find a convenient way to collect information on them, but the gist of these is that they're items that I'm pretty sure drop from elites, and mimic the different effects those elites have attached to them.

Aurelionite's Blessing

• Turns you gold!
  
• ???

Her Biting Embrace

• Applies slowing effect on hit to damaged enemies.
  
• This is dropped from ice elites/bosses.

Silence Between Two Strikes

• It HALVES your health, and turns the other half into quick-recharge shields. For every attack it creates a dot that explodes after 1 or 2 seconds.
  
• This is dropped from electric (enemies that also have the exploding dot effect) elites/bosses.

Ifrit's Distinction

• It turns your character red/on fire, gives them horns like the "Blazing" elites, and greatly increases attack speed + move speed. Your character also set enemies on fire with attacks, and leaves a trail of fire behind them that burns enemies.
  
• This is dropped from fire elites/bosses.

N'Kuhana's Retort

• You have the same effects on enemies as Malachite enemies do on you. You disable enemy healing, and you occasionally shoot out spiky Malachite blasts in a handful of different directions that deal damage when stepped on by enemies.
  
• This is dropped from Malachite elites/bosses.

Spectral Circlet

• You gain a hefty slow on hit effect (stronger than that given by Her Biting Embrace) and make nearby friendlies invisible. Not sure what this actually does for those invisible friendlies, did some testing and enemies definitely still target them.
  
• Note: Yes the image above is blank, that is how it appears in game in your equipment slot.
