Causing lightning strikes at any other markers you've cast: When the duration of any marker expires, lightning will strike it, then all other pending markers will expire in quick succession, each dealing damage at their location.

Chance for Lightning to Strike the Marker when Cast: Lightning striking the marker due to the quality effect causes a lightning strike to happen at cast time, in addition to the strike that will happen when the duration expires. The extra strike from the quality effect does not cause lightning strikes to happen at any other pending markers.
