Ferocity

Ferocity is a resource used to fuel champion abilities in place of mana. The resource bar is black while empty (similarly with most manaless champions), it turns grey while charging and, finally, it is orange when fully charged. Currently, when fully charged, ferocity enhances the champion's next ability, consuming all ferocity in the process.
