Until this grapple ends, the septon can't use this tentacle against other targets. The septon has seven tentacles, each of which can grapple one target.

Lightning Network.The septon conjures a field of electricity that fills a 30-foot cube originating from itself before dissipating. Each creature in that area must make a 16 Dexterity saving throw. On a failed save, a creature takes 33 (6d10) lightning damage and has the stunned condition for 1 minute. On a successful save, a creature takes half as much damage only. A stunned creature can repeat the saving throw at the end of each of its turns, ending the effect on itself on a success.
