Rockchomper

has a casting value of 5. If successfully cast, pick
1 friendly unit of Ogor Gluttons wholly within
18" of the caster that is visible to them. Until the
start of your next hero phase, if the unmodified
wound roll for an attack made with that unit's
Gulping Bite is 6, that attack inflicts 1 mortal
wound on the target in addition to any normal
damage and that unit can heal 1 wound
allocated to it.
