Black Orbs. A somewhat rare orb, but can be produced by ANY enemy. A very special orb in that it changes the laws of physics around you temporarily, and there are many different forms of change. Reversed gravity, low gravity, Vampire damage (dealing out damage heals the attacker equal to how much damage was given for both enemies and the player), time reverse (which will reverse the current scene five seconds backwards), invisibility, and more, including ones that would be bad for the player, including double enemies (not bosses), temporarily invincible enemies, frozen player, etc. Black Orbs are collectible and used at any time, but they are a gamble.
