Black Hole

is one of the Special Abilities available in For The King.

Overview
This passive is a skill currently exclusive to the Astronomer. A black hole is summoned, killing the enemy instantly regardless of their immunities or health. Any loot that would have been received from that enemy, including XP and Gold, is forfeit. However, if the enemy steals something from one of the heroes during the battle, the stolen property will still be recovered when the enemy is killed. In exchange, Star Matter is dropped at the end of the battle equal to how many black holes were summoned. This skill can be activated with any single target attack, even if the attack doesn't do damage or if the weapon is unconventional to the Astronomer.

Black Hole has a (6% + 2% for each focus you spent) chance to proc, BUT then it gets halved for every Star Matter you have on your team. Therefore the more Star Matter you have, the less often Black Hole will proc.

Although it was originally reported to work on Scourges, this was patched out of the game shortly after release of the Lost Civilization DLC. It will no longer work on Bosses or Scourges.
