Sorry if this is very obvious to all of you, but I get confused over what Zerkova’s FEAT actually stops? What qualifies as a special action or attack? Is shield guard a special action? Sucker? Harbinger’s Martyrdom ability? I got the whole no shooting, but what about Magic ranged attacks? Again sorry if this is silly to some of you, but I guess I have struggled with special actions etc., all along.
I believe a special attack or action is something you choose to do during your activation instead of a regular attack. So not shield guard or sucker as these are not things you choose to do instead of an initial attack.
Also iirc all "special" anythings have a star next to their name on the back of the model's card?
Hex Bolt has many very strong applications in the current meta. Things like stopping the Hermit's spells, Storm Raptor's *Energy Pulse, almost every non-focus/fury/essence user's spell-casting, preventing tramples (relevant against Siege Animantaraxes, etc.). The list goes on.
