Recommended Ability Unlock Order

The default ability unlock order works for most players, but speed-runners and Pro Mode players often deviate. This guide explains why Assemble is almost always the right first unlock, when shuffling Auto-Shelving earlier pays off, and the one build (No Magic) where the entire ability tree is irrelevant.

The full step-by-step version of this guide is coming soon. We are verifying the details against community runs and the official Clean The Library wiki before publishing the longer walkthrough, so the public version stays accurate.
