Those two warhounds would make an absurd number of shield saves throughout the game. Well over 30, with 20 hit rolls in a single turn only dropping 2 void shield levels with enough blanks on the reactor die to force only a single ineffective reactor overload.
The Pale King on turn thee would unload onto the pair, catching a third dog in the belicossa blasts, but wouldn't dispatch them and would be laid low by the opposing Mortis warlord's cannons.
