Freddy, Bonnie, Chica, Foxy, and Springtrap will pursue the closest character every apocalypse turn. If an animatronic reaches a character, that character takes 5 D20 of permanent damage.
Springtrap always moves with 7 speed. All other animatronics do not have guaranteed movement, instead only moving according to the FNAF Dice. The amount of FNAF Dice rolled increases by 1 for each apocalypse turn that has passed. Apocalypse turn 1 = 1 roll, Apocalypse turn 2 = 2 rolls, etc...
Every other apocalypse turn, the animatronics turn invisible before they move. They will still deal damage while invisible, and they will be revealed at the start of the next apocalypse turn.
