Some Emissaries of the Great Maw drag behind them huge cauldrons, used to make offerings to their ravenous god.
This character replaces the Impact Hits (2) special rule with the Impact Hits (D3+1) special rule. In addition, during the Command sub-phase of their turn, if they are not engaged in combat, a character with a Butcher’s Cauldron may attempt to make an offering to the Great Maw by making a Leadership test (using their own Leadership). If this test is passed, until your next Start of Turn sub-phase this character and any unit they have joined gains the Regeneration (5+) special rule. However, if this test is failed, this character immediately loses a single Wound.
