Sometimes Icy Claws can already be at 100% chance, and the upgrade does not seem to give anything. Maybe add 10% speed reduction on upgrade? That was the upgrade always gives a little something.

I'm not understanding natures. The yellow triangle is yellow. The "nature colors" are red, purple, blue. Yellow is not red, blue, or purple. Yellow triangle I *think* is physical. It should have a circle, the "physical symbol", in its center, not a diamond, which is the "magical symbol". The rest of the enemies do match either red, purple, or blue. Can it be trusted that their color matches their nature? Sometimes enemies spawn inside a black void so you can't tell their nature based on where they spawned...

The structure's antenna was in the far left corner which was in darkness. Was unable to unlock the structure.

I think it would be nice if there was a move option for artifacts, kind of like repaint. Would let you choose and move a new artifact to one of the other two units as wanted. Can buy more charges like repaint.

So, apparently it's possible to get offered a cursed artifact of normal/common quality, which then requires you to sacrifice an artifact of junk quality, which don't exist in game. https://steamcommunity.com/sharedfiles/filedetails/?id=3463139955
