He has advantage on Dexterity saving throws and checks, his movement speed is doubled, and his jump distance is tripled. His extra attacks become four, and Flurry of Blows grants four attacks. None of these benefits require ki. He regains all ki when entering the state, loses 1 ki at the end of each round, and must make a Constitution saving throw if he has 0 ki at the end of a round. On a failure, the state ends, he gains 4 points of exhaustion, and takes 10d10 necrotic damage. When hit, he rolls a d20 and compares it to the attack roll without modifiers. If his result is equal to or higher, the attack misses regardless of its final total.

When Spectre reaches 0 hit points or is subjected to an effect that would kill him instantly, he can roll a Constitution saving throw with a DC of 10 plus the number of times he has dropped to 0 hit points. On a success, he regains hit points equal to his monk level plus Constitution modifier plus 12 hit points per ki point spent. On a failure, he can still revive by expending all remaining ki. If he has no ki or chooses not to revive, the original effect applies.
