New to the game with a quick question

[Santan75]

 Building my Maggotkin Army and was going to run a Plague Cyst with Lord of Plagues 2 x 5 Blightkings and 1 10 Blightkin with a Rotbringers Sorcerer for a 1000 point game my question is if all my Blightkings stay within 7" of my Lord of Plagues they can reroll all misses every time? So on my 30 rolls with the 10 blightkings I can reroll all misses and 6 explode?

The Lord of Plagues allows you to re-roll hit rolls of 1.  So any unit of Blight Kings that are within 7" whilst fighting will be able to re-roll any To Hit dice that are a 1*.  Once all rolled & re-rolled any that are a 6 explode into D6 hits.

* you can never re-roll a re-roll.
