Zogwort's Curse is used instead of the normal roll on the Weirdboy chart. Some of the items on the chart count as shooting attacks, but it doesn't say that using the power itself is a shooting attack.

Granted, we are talking about a very rare occurrence; for this to come into play Zogwort would have to get into base-to-base with your Command Squad HQ and survive a whole round of combat, maybe more if he was the one who charged in. Better to just keep him away, and not worry about how it works out.

That or kill Zogwort first (he's only I 2).
