As you can see, many of these achievements you'll obtain simply by playing the game for a while. Some examples include "The Basics", "Advancement", "Elite Slayer", "Slaughter", and many more. However, a few of these challenges can be rather tricker to complete, and you'll need to actively focus on completing them. Let's take a look at a few of them below.
Discovering the hidden chamber in the Abandoned Aqueduct will net you two very nifty on-hit items. You've probably passed the entrance to this chamber before now (the giant circular entrance in the cliff face at the edge of the map), but not known how to enter it. Turns out there are two switches in the floor, randomly placed nearby, which must be stood on simultaneously to unlock the chamber. Easy in multiplayer, but in singleplayer you'll probably need to pick the Engineer, whose turrets can be placed on these switches.
Inside, you'll need to defeat the two unique Elder Lemurians inside (hint: don't let them get close) for them to drop their respective items and complete the challenge.
This is basically just a matter of exploring each map fully. Newt Altars appear randomly in certain fixed locations, and you can pay a Lunar Coin into them in order to unlock the Bazaar Between Time after you charge that stage's Teleporter. They may appear in any Environment, often in hard to reach locations, which means it might be an idea to pick Huntress, whose teleport ability enables her to easily reach more inaccessible areas. Remember that you'll need to actually activate these Newt Altars in order to complete the challenge.
Another challenge that might initially be met with confusion, but is actually very straightforward once you know what to do. Finding the Altar to N'kuhana requires you to be in the Wetlands Aspect Environment (you'll often find yourself here in the second stage). Find the cliff, and look for the hidden cave down below, marked by the tree root that sticks out from the wall.
Dropping into that cave introduces you to a hidden area, awash with green and creepiness, with a floating skeletal child-like thing in the centre of the cave. Shoot and kill the thing, and you'll complete the challenge, after which you can drop down into the green, which transports you back up to the surface. Simple!
Moon Worshipper requires you to carry 5 Lunar Items in a single run - a tricky thing to do if you're not sure what Lunar Items are or how to get them. In fact, this is easier than you might think.
Lunar Items require Lunar Coins to be bought or unlocked. These Lunar Coins are dropped occasionally by enemies, and you can see how many you have just under your gold in the top-left of your screen. Crucially, your number of Lunar Coins persists from run to run, so the idea here is to save up until you have at least 5 Lunar Coins, then try to exchange them for Lunar Items in a single run, either by seeking out Lunar Pods to open or by visiting the Bazaar Between Time via the Blue Portal which sometimes appears next to a charged Teleporter.
This one is actually fairly easy, but may be confusing if you're not sure what it's talking about. First you'll need to find a Shrine of the Woods - a green shrine only found in the Distant Roost, which you feed gold into in exchange for a healing aura that heals you and all allies over time. Paying gold into the same Shrine of the Woods three times in a row will fully upgrade the healing radius, completing this challenge for you.
The Timed Security Chest can only be found in Rallypoint Delta. It's usually fairly easy to find, but it'll lock 10 minutes into your run, which means you'll need to speedrun your way to the third stage in order to unlock the Chest and unlock the Preon Accumulator item.
There are three possible spawn locations for the Timed Chest: it'll be either inside one of the large containers on the ground; inside the top container in a stack of containers; or next to the radar tower on the hill.
The Pause challenge is also not too difficult at all, but it does require a little patience in collecting the 11 necessary Lunar Coins - one to donate to a Newt Altar so you can reach the Bazaar Between Time, and the remaining ten to spend at the Bazaar on the crystal within which contains the Artificer, the fifth playable character in Risk of Rain 2.
Another which is actually fairly straightforward, but requires some dedication to unlock. The Obelisk in question at which you must obliterate yourself can only be found in "A Moment, Fractured" - a hidden Environment which can only be accessed via a Celestial Portal. These white portals appear at the third stage of every "Loop" after your first - that is, you'll need to have looped back to the first stage, and then got to the third stage again, where you will find a Celestial Portal. Once you find the Obelisk in the hidden Environment, you will be prompted as to whether you'd like to obliterate yourself and end your run. Doing so will complete this challenge and unlock the Mercenary, the final playable character in the current build of Risk of Rain 2.
And that's all you need to know regarding the various Risk of Rain 2 challenges it is possible to complete. With a bit of patience and dedication, you'll soon have all sorts of new items and characters to test out and help you survive longer in the never-ending rain.
