So as a player who came in some time very shortly before early access (I kept an eye on the game earlier but didn't get myself over hyped on info) I'm somewhat interested in hearing what features are planned for the game that haven't made it in yet. Mainly because of some confusion caused by bad info I may have gotten.

1. I know raids are planned for the game later, but I assume there are none now? Is the crystal tower going to be the only one for a bit?

2. One of my friends mentioned that they were going to add cosmetic slots. Is this true or does he not know what he's talking about?

3. I had heard somewhere about Hardmode dungeons for level capped players where you'd need a full party to do it and there would be more bosses and the current bosses would do new things. I'm pretty sure this isn't in the game right now (aside from hardmode primals) but do we know if this is an actual thing which is coming or did I get confused again? (This is the one I'm really interested in.)
