Venom of the Spider God

Range: 18"
—
If successfully cast, pick 1 friendly
SPIDERFANG unit wholly within range and
visible to the caster. Until the start of your hero
phase, add 1 to the number of mortal wounds
caused by the 'Spider Venom' ability of that unit
if the unmodified hit roll was 6. If the casting
roll was 10 ore more, pick up to D3 different
friendly SPIDERFANG units instead of 1.
