What the game does not explain. Each answer is short and links to the full guide.
Void items (the purple ones) are versions of normal items. When you pick one up, every copy of the normal item turns into it, one for one: with 3 Ukulele
and one Polylute
you have 4 Polylutes and no Ukuleles. While you hold it, each new copy of the normal item is converted on pickup.
That is what «corrupts» means: Polylute
corrupts Ukuleles, Benthic Bloom
corrupts Clovers, Encrusted Key
corrupts Rusted Keys... Newly Hatched Zoea
corrupts every yellow (boss) item. They only exist if the Survivors of the Void DLC is enabled when the run starts. There are 14.
Normal chests never drop them. They come from:
Careful: the Void Fields give normal items, not void items.
The purple cradle found on some stages. Opening it costs 50% of your health and gives 1 void item: 60% common, 30% uncommon, 10% legendary. Up to 4 Void Infestors can pop out: small creatures that jump into enemies and make them Voidtouched elites. Open it at full health with no enemies around.
A hidden stage. You enter through the Null Portal in the Bazaar Between Time, down the path under the blue portal, once per run.
A separate game mode, picked from the menu. It comes with the Survivors of the Void DLC. You defend a bubble against endless waves: every 5th wave is a boss and every 10th the enemies gain an item. After each wave you pick an item from an orb, and some orbs are purple, with void items.
Reaching wave 50 completes the challenge that unlocks the Void Fiend
(the other way is escaping the Planetarium).
The blue items. They always give something strong and take something away: Shaped Glass
doubles your damage and halves your health. Chests never drop them and gold cannot buy them; you pay with Lunar Coins:
They cannot be scrapped. To get rid of one, use a Cleansing Pool.
Lunar Coins carry over between runs (gold does not). Ways to get them:
Find a Newt Altar on the map (a small statue, often hidden) and pay 1 Lunar Coin before the teleporter finishes. When it is charged, the blue portal appears. Paying afterwards does nothing.
Inside, time stops, so difficulty does not rise. There are:
Do not hit the shopkeeper: hurt him enough and he kicks everyone out.
Yes, at a Cleansing Pool, found on some stages. It takes one random lunar item you carry and gives a Pearl
(80%: +10% max health) or an Irradiant Pearl
(20%: +10% to every stat).
An elite is a normal enemy with much more health and damage (the basic ones: 4 times the health, twice the damage) and a power. Its name and colour tell you which:
After the first loop the tier 2 elites show up, much tougher:
Plus two special ones: Perfected (lunar enemies and Mithrix) and Voidtouched (from Void Seeds). Each elite has a 1 in 4000 chance to drop its «aspect», an equipment that gives you its power; 57 Leaf Clover
raises that chance.
It is the exit of each stage. Activating it spawns a boss and a big red circle, and it starts charging:
Until you use it, grab what you can: the clock keeps running and difficulty keeps rising.
They appear next to the teleporter when it finishes (or wherever noted):
On stage 5, taking any portal sends you back to stage 1.
On stage 5 you can go fight Mithrix or go back to stage 1 with all your items: that is looping. Align the Primordial Teleporter with the planet, or take any portal on stage 5.
After the first loop come the tier 2 elites, the celestial portal every 3rd stage and new variants of some stages. Difficulty keeps rising: each stage multiplies it a bit more.
A hidden stage. Pay the Altar of Gold before the teleporter finishes and the gold portal appears. There are 7 beacons: lighting the 4th spawns Aurelionite, a golden giant that takes no damage while any beacon is off. Beating it gives each player a Halcyon Seed
: Aurelionite then fights for you at every teleporter.
The celestial portal (after the first loop) leads to A Moment, Fractured. The Obelisk is there: obliterating yourself ends the run for everyone, gives 5 Lunar Coins and the first time unlocks the Mercenary
. If someone carries Beads of Fealty
, you go to A Moment, Whole instead, with 10 more coins.
Each 57 Leaf Clover
gives 1 luck: when something is down to chance (an item triggering, a critical hit...) and fails, it is rolled once more per clover. A 5% item becomes 9.7% with one clover and 14.2% with two.
Purity
(lunar) does the opposite: each one cancels a clover. Luck does not change chest contents, the Shrine of Chance or Tougher Times
.
Optional goals («do this with that survivor»). Completing one permanently unlocks something: a survivor, an alternate skill (the locked ones on the character screen), a skin, an item or an artifact. The first time they give 1 to 10 Lunar Coins.
They are in the menu: Logbook → Challenges. Mastery skins are only earned on Monsoon.
Equipment is the orange item: it does nothing by itself, you trigger it with its key like an extra skill, then it has a long cooldown. You carry only one: picking up another swaps them. There is lunar (blue) equipment too, and elite aspects are equipment. Items like Fuel Cell
shorten the cooldown.
A «proc» is an item triggering on hit (the dagger causes bleed, the ukulele fires lightning...). Each attack has a number saying how much it counts: 1 counts fully; at 0.6 the Tri-Tip Dagger
goes from 10% to 6%. Very fast attacks usually count less. Bleed, burn and sticky bombs count 0: they never trigger other items.
In Risk of Rain 2 difficulty rises with the clock, not with stages: every minute enemies get stronger, and each finished stage multiplies it a bit more. That is why speed matters. The clock stops in the Bazaar.
At the start you choose how fast it rises: Drizzle (easy), Rainstorm (normal) or Monsoon (hard). Eclipse is a mode with 8 levels, unlocked by winning with each survivor.
Damage goes in this order: barrier → shield → health. You die when health reaches 0.
