On one hand, this feels unnecessary. We already have stronger woods, (ebon/shade, ash) and this would seemingly result in another forest but with different trees. On the other side, I would very much enjoy something like this. The armor and bow look great, and a new biome that featured these would likely look amazing. Might have me come out of the snow biome for once.
Edit: I didn’t see the other tools. They look simple in a good way. The trees and hammer could use some cleaning up, however. Specifically the hammer’s head and the top of the trees. I’d also be curious on how the spawns would differ from those of the forest. Judging from the slightly higher power of the wood, the challenge should be present, though nowhere near that of the world evil. Maybe a pre-HM wolf variant?
