Flask of Congealed Maw-juices

Once per battle, at the start of the hero phase, you can pick 1 Mawpit in your army that is within 9" of the bearer and that has been affected by a rule that says you cannot use the scenery rules on its warscroll (such as Smash to Rubble) and roll a dice. On a 2+, that Mawpit is no longer affected by that rule and you can use the scenery rules on its warscroll once more.
