Hello all,
Read the 5th ed rules for assaulting into cover. Specifically, read what must happen in order for a unit to strike at I1.
Now read the 'Flip Belts' rule.
If harlequins are accompanied by a Shadowseer, it's a moot point. But if they are NOT, then it seems they will strike in initiative order anyway. I'm hoping I'm wrong here; someone tell me why.
