Since the 10th edition Leagues of Votann index came out, there have been several discussions about the lack of synergy between the Lethal Hits ability (auto-wound on a critical hit) given by a Kahl when he's leading a unit, and the Devastating Wounds ability (mortal wounds on a critical wound) on Volkanite weapons (which he can take himself, or be carried by a Hearthguard squad he leads). Some claim that Lethal Hits is a debuff to these weapons. Others, such as a previous version of this article, have claimed that this is wrong.
Lets once again investigate how these rules interact for the Leages of Votann Kahl.
