Description: The Water in the Water can never be part of another Hero model's warband. When you deploy your army, do not deploy the Water in the Water on the board - instead keep it to one side for later. During each Priority phase, after Priority has been rolled, announce if you would like the Watcher to arrive and if yes, roll a D6. On a 3+, the Watcher is ready to enter play. Once you have declared the Watcher is ready to enter, you must roll during each Priority phase thereafter until it is available.
When the Watcher is ready to enter play, immediately place it anywhere on the battlefield - it can displace models. Move any displaced models the minimum distance possible so that they are 1" away from the Watcher (or as close as this situation will allow). In this situation, players take it in turs to displace models, starting with the Watcher's controlling player. This may create some odd situations, but represents the Watcher bursting forth, scattering warriors both friend and foe alike. The Watcher cannot charge on the turn it arrives.
