If you don't want to be spoiled for these achievements, and want to find and unlock them yourself, skip this guide for now.

To get this achievement, simply unlock the Assessor.

The easiest way is to complete a relic hunt run and select the Assessor when prompted.

To get this achievement, you must reflect a sphere 40 times in a row.

You'll need to unlock sphere reflection to get this achievement. Find a spot relatively far down the map where the rocks aren't too weak, and let a sphere reflect off of your Reflection Field a bunch. Spheres are powered up on reflection, even more with Improved Reflection, so keep that in mind. If your spheres are dying too soon for it to reflect 40 times, upgrade your sphere lifetime.

To get this achievement, you must have a sphere fly for 23 seconds or longer.

Option 1: The simplest way to get this is just upgrading sphere lifetime a bunch until the sphere can survive for 24 seconds. Then, shoot your sphere.

Option 2: The achievement text specifies you can't use the reflect upgrade to keep the sphere alive for the 23 seconds, but it still works as far as I know. Upgrade your reflect skill and bounce it all over some rocks. This isn't how I unlocked the achievement and I'm not sure if it works anymore after the Re-Assessor update. Please let me know if it's still working after the update.

To get this achievement, you must shoot a bundle of 25 resources or more.

You don't need to shoot the bundle into your dome to unlock this achievement, so shooting it anywhere is fine.

To get this achievement, you need to have 6 spheres at once.

Full Clip is real easy to get, just upgrade your Sphere Supply enough times to hold 6 spheres, then wait for all of them to regenerate.

To get Hat Trick, using the Explode Spheres upgrade to explode 3 spheres at once.

Another super easy one. Upgrade Supply Spheres to hold 3 (or more) spheres, buy the Explode Spheres upgrade, and make sure to explode all 3 spheres at once. Easiest way is to just go into some secluded deep part of the map and just spam all your spheres out until you run out, then spam explode.

To get this achievement, split a sphere into the 5th generation (split a sphere 5 times).

This one's a little more time consuming, the best way to get this is to unlock the Split Spheres upgrade, unlock Improved Split, and upgrade Sphere Lifetime as much as you can. After this, go somewhere pretty claustrophobic and shoot off a sphere. Try to split the sphere somewhere where they'll be able to bounce as much as possible so that they stay alive longer. Do this 5 times and you've got the achievement.

I hope this guide helped! If you're feeling generous, and I helped you out, I don't mind awards at all! Please let me know what I should change/add to this guide in the comments.
