The neutral board takes the damage. Each neutral board starts with 3 qi.
Neutral boards start the game with 3 Qi tokens. They may lose them but never get them back.
For each Tormentor on the neutral board, a player must roll the Curse die and apply its effect for the neutral board (the green Taoist’s power is ineffective for this die roll). Remark: if the curse die indicates „loss of Tao tokens“, you are lucky as this has no effect on a neutral board.
If the neutral board runs out of qi, then it becomes possessed, and follows the usual rules for a possessed board (same as a dead player).
A neutral board that has lost all Qi tokens is called „a possessed board“, Its specific power cannot be used anymore through neutral power tokens.
Any further loss of Qi points (i.e. board overrun or tormentor) must be endured by a player of your choice (the green Taoist’s power is ineffective if Qi loss is due to the curse die).
