Step

Step has two meanings in Sorcery!

1. A step is the smallest measure of distance in Sorcery, equal to the distance between two adjacent locations in the same region, e.g. "up to 2 steps away" on cards like Dispel.
2. A step is also the smallest distance a unit can travel when moving, e.g. "take a step" on cards like Leap Attack.

If an effect uses "up to X steps away," use the first definition. Movement abilities do not apply because you're not moving anywhere, you're checking distance. Simply count 1 adjacent square per step, without crossing region boundaries. Examples include Payload Trebuchet and Sleep.

If an effect uses "push/pull/drag one step," also use the first definition, because the unit is not moving of their own volition. This is forced movement. Simply count 1 adjacent square per step, without crossing region boundaries. Examples include Whirlwind and Wind Sylph.

If an effect uses "take a step" or "move one step," the unit is moving itself and may use abilities like Airborne, Voidwalk, Burrow, and Submerge, crossing region boundaries. Use the second definition. An Immobile unit could not "take a step" at all. Examples include Guile Sirens, which could make a nearby Airborne enemy take a diagonal step toward them, and Leap Attack, which could allow a Burrowed minion to unburrow to the surface and strike all the units there.

Note that the Moves Freely ability only applies during the "Move and Attack" and "Defend" basic abilities.
