Overall Rating: Red. This means that
investiture of stone isn’t going to contribute to the effectiveness of your character build at all.
Overall Notes: The resistance to bludgeoning, slashing, and piercing are pretty useless in Tier 3 because most creatures will have magical weapons. The passive effect allows you to move through the earth but ejects you if you end your turn there so you can’t travel far distances. The action effect is terrible, it doesn’t even do damage. Also, requires concentration so you can cast the spell, and lose it before you’re able to use any features.
