Vitapod
From SpiralKnights
Vitapods are items that add a number of units of health to the knight that picks it up by walking over it. They appear as white capsules with red markings showing the number of health bars that will be added. When you run over a vitapod, you will pick it up automatically, if it has a higher number than your current vitapod (or you do not have a current vitapod). Vitapods cannot raise a knight's maximum health above 40 units. Because the health bars added by a vitapod are empty, players will need to find hearts to fill the additional bars.
Vitapods are always used by the knight that picks them up whether the loot distribution of the party is set to free-for-all or round robin.
You can drop your vitapod by clicking on the symbol in your HUD and dragging it to the area near your knight.
