At the Astrotorium, even the dead make a living wage.

Night Shift of the Living Dead

After you roll a die, you may pay 1 life. If you do, increase or decrease the result by 1. Do this only once each turn.
Whenever you roll a 6, create a 2/2 black Zombie Employee creature token.

If you roll the planar die in a Planechase game, you can pay 1 life, but you can’t alter the result of the roll. This would still “use up” the ability for the turn.

The first ability can affect only one die, even if you roll multiple dice at the same time. However, you do get to see all the results before deciding whether to use it, and if so, which result to shift.
