A learning-order tier list

If you wanted a power ranking, stop here and read the empty damage column on weapons. This page answers a different question: which key is worth learning before the others, given that the developer only published names.

Editor learning order. Not an official strength list. Last checked 30 Oct 2026.
OrderToolWhy this earlyBasis
1Portal Gun (T)Editorial recommendation: learn the central travel tool first.Developer names it first among the tools people must touch.
2Regenerate (E) and Blender (F)E is named Regenerate; its exact effect is not specified. F has an explicit entry condition.Both are in the description. F has a condition.
3Dimensions (R)Editorial recommendation: explore R after learning T. The menu contents are unverified.The key is official. The contents are not.
4Mech Blaster (X)A fight tool once movement works.Name only. A wiki calls it ranged. Single source.
5Robo Arms (V)The last named tool. Same lack of numbers.Name only. A wiki calls it melee. Single source.

What this list refuses

portalsandboxwiki's own tier page uses a learning ladder and says it will not fake damage ranks. I am doing the same job with the official names in front of me. If a later patch posts cooldown or damage, the table should be thrown out and rewritten. Until then, practicing T before X is the whole recommendation.

Questions

What is the best portal gun?

No published comparison establishes a strongest option. Rick Prime, Prototype, and Evil Morty are passes. Their descriptions do not specify damage.

Where is the value list?

There is no priced value list. Pass prices were not visible while the experience was private, so a value ranking would be made up.
