So, i've been around the net for a few mins and everything i got on spiral knights so far are some lame phishing "energy generators" (if you see "everygy generator" written anywhere, dont bother. its a scam).

apparently everything important is server-side, but i still have some ideas. for instance, i believe things you drop in dungeons are accumulated client-side until you finish it so then your client sends how much items you earned to the server. still have to test this one out, will start out with heat as soon as i get alone in a group.

There is a "Go solo" option in the party lobby.
