Vitapod
From SpiralKnights
Vitapods are items that increase the maximum available health of a knight.
Description
A white capsule with a red and white heart icon on top, each vitapod has a red number on its side indicating the amount of health bars the player will gain. Because the health bars added by a vitapod are empty, players will need to find hearts to fill the additional bars.
When you run over a vitapod you will pick it up automatically, as long as it has a higher number than your current vitapod (or you do not have a current vitapod). You cannot drop your vitapod, unless you leave the party.
Trivia
The value of the vitapod is always evenly divisible by the tier it is dropped in. Although stronger vitapods have been available in earlier versions of the game, the strongest vitapod currently available gives 21 more health (only achievable in the Shadow lairs).
Along with vials, vitapods are the only other items that are only accessible to the knight who collected them (unless dropped again for a team mate).
