The moon: the way to Mithrix

Commencement is the moon of Petrichor V, where Mithrix, the final boss, waits. You get there from stage 5 and there is no way back: either you win and escape, or the run ends. 52.1% of Steam players have done it. How to beat him, phase by phase, is in the Mithrix guide; this is the way there.

// what you need

What you need.

Reaching stage 5 (Sky Meadow or Helminth Hatchery).
Spending your gold before going: there are no normal chests on the moon, only Cauldron to trade items and Lunar Pod.
A damage equipment for Mithrix's phase 4, when he steals your items.

// step by step

Step by step.

Pass stage 5: its teleporter is the Primordial Teleporter. Leave it aligned with the moon, with the closed spiral, as it appears. If you touch the spikes around it, it turns toward the planet and sends you to stage 1 (the loop).

Charge it and you arrive at Commencement.

Charge 4 pillars out of the 4 to 7 that appear, spread over four areas, standing inside their circle like a teleporter: Pillar of Mass (60 s), of Design (30 s, with pushing waves: jump), of Soul (30 s, the circle shrinks and loses charge if you leave) and of Blood (10 s, but it takes 10% of your health per second).

Go up to the arena: with four pillars charged the jump pads light up. In co-op, everyone has to go in.

Beat Mithrix through his four phases (hammer, throne with chimeras, blue hammer and the item theft). Step by step, in the Mithrix guide.

Escape: the moon blows up in 3 minutes. Jump into one of the portals floating around the arena, run to the ship and stay in its zone for 1 minute. The run ends: you have won.

// what you get

What you get.

10 Lunar Coins every time.
The Captain the first time («Washed Away» challenge).
On Monsoon, also the lunar item Purity and the mastery skin of the survivor you are playing.

// watch out

Watch out.

If you touch the Primordial Teleporter's spikes by mistake, touch them again before charging: the spiral has to be closed to go to the moon.
The pillars can be skipped with mobility (Loader with her grapple, Artificer flying, Mercenary with Purity), but in co-op everyone has to enter the arena.
In Commencement, the glass frog opens the portal to the Planetarium if you pet it 10 times (1 Lunar Coin each): the moon's other exit.

FAQ.

How do you get to the moon in Risk of Rain 2?

Pass stage 5 (Sky Meadow or Helminth Hatchery) and charge its teleporter, the Primordial one, aligned with the moon (closed spiral, as it appears). It takes you to Commencement.

What if I touch the Primordial Teleporter's spikes?

It turns toward the planet: when charged you return to stage 1 with everything you carry (the loop). You can touch them again to align it with the moon once more.

Do you have to charge the four pillars?

To go up by the jump pads, yes: four of the ones that appear. Some survivors with a lot of mobility reach the arena without them, but in co-op everyone has to go in.
