This is a super simple idea
Basically this would function like all the other prize blocks in the game, you pop it and good stuff comes out. The difference being that this block spawns at the end elevator on the first floor, and the end of whatever floor you are on when someone joins the party.
This particular box looks like an HP box with gold trim, however, instead of dropping HP this will ALWAYS drop a Vitapod.
One of the most annoying and frustrating things in this game is trying to get through tough missions when you don't get a vitapod till the third floor. By then many players die, give up, or just stop playing SK for a while for something.... more fair. When I don't get a vitapod till just before I get to the Danger mission Boss or the 3rd Floor of FSC it feels like the game is trying to slip it's hand into my Sparks of Life Wallet (FYI you try that to me IRL and you get shanked).
