Okay, been playing a while, but I have a question, it may be a bug, or may be an intentional game design (I hope not):

When someone else in your party revives you after you die in a dungeon, is your mist energy cost supposed to double anyways?

Example:

Death 1 - Cost 2 energy to revive, use energy
Death 2 - Cost 4 energy to revive, party revives
Death 3 - COsts 8 energy to revive, party revives
Death 4 - Costs 16 energy to revive ....

Just starting out so I'm not sure if I unknowingly disabled this or if it might be a bug, but according to the 2nd level of the training grounds and a friend of mine who also plays, I should have some sort of vial belt at the top of the screen where I can hotkey vials to throw? Whatever it's for, I don't have it on my screen. Is there a keyboard shortcut I mistakenly pressed to get rid of it or is it some sort of bug?

I have played pretty far into a level before but I have never finished one. I was just wondering what happens when you get to the end. Is it important to finish the levels?

I'm not exactly an expert on statuses and resistance and all that... So I'm wondering if it would be worth it to set yourself on fire with a Fang of Vog and wear elemental defense gear so it spreads to other monsters without hurting you too much. Also, does status resist prevent the status from happening or does it lower the damage taken?

A couple places on this forum, there's announcements that the NDA was lifted. I never saw one anywhere when I was signing up, but when I verified my email address I saw this:

*** Please Note: Any information regarding Spiral Knights, the Preview

Is this just something that hasn't been removed yet, or should I have not shown all my friends? If the latter... oops... sorry...

I'll keep it short: could I combine the effects of, say, a bomb that lights enemies on fire and a bomb that causes stun so that I can keep my enemies from attacking AND keep them on fire all at once?

I have all 2-star equipment equipped, I've played through all of the gates as far as I can, and when I go talk to the Spiral Warden he tells me "Welcome to [whatever, can't remember his words exactly]" but I can't pass through the force field to get to the next elevator.

Is there a way to tell exactly what I'm missing?

Can I trade enemy drops like gel cores? How about guns, upgrades, and trinkets? is there a limit to what I can trade?

I'm still pretty new to the game, but I have gotten to the point where I am shopping around for new items / stuff for crafting.

The vendors in Haven for example, their inventory changes correct? How often does this happen? Is it day to day or something?

I realize this question's probably really stupid, but I've never played a MMORPG before. How do I talk to my party in a dungeon? Or other people in town? I couldn't find a text box or a way to open one when I tried to look and we were running through the dungeon so I didn't have much time to find one.
