Game Mechanics: Zero health to full from being unconscious

[Schmandis]

While on my lvl 9 Bard with Hymn of Restoration on I was poisoned at low health. While sitting with the song on, I became unconscious three times. While unconscious for the third time, the poison wore off, and my client displayed a health value of -1. Once the server tick happened I stood up with 100% health.
