If hes killed while a bog trog within his command can be killed instead to heal 1 dmg

Rask feat is: While in Rask's control area, friendly faction models cannot be targeted by attacks or charges made by models more then 5" away from them. Dark Waters last for one round."

Oh great and powerful Barnabus...strip focus and upkeeps off with his gun, then fury up a beast? Terminus and colossals might no longer be auto lose for Blindwater if true. Though even with only a command of 5, there has to be some special wording on that bog trog sacrifice ability. Just so silly good.
