Curse of da Spider God

If successfully cast, pick 1 enemy unit within range and visible to the caster. Until the start of your next hero phase, hit rolls for attacks made by that unit always fail on an unmodified roll of 1 or 2 instead of only on a 1, and save rolls for attacks that target that unit always fail on an unmodified roll of 1 or 2 instead of only on a 1.
