Biomes & Nature I think you should add a Hardmode use for Obsidian and the Tundra

[Elocky]

Once you get to hardmode, obsidian is pretty much useless so I think something like a obsidian weapon would be cool. also maybe obsidian + Chlorophyte to make another set?

I also think there should be some sort of reason to go in the Tundra after WoF but other than the shell and weapons, there isn't much compared to other biomes.
