I'm still not sure with the wording of the rules. zone attacks state (page 23 rule book) states "therefore abilities and traits that allow a target to react when it is the target of an attack do not apply to zone attacks"
force field states "when ever you are attacked ....etc", most enchantments are traits so from this wording I see force field will not prevent damage from zone attacks
Hail of stones. Even if you are fast like the ferret you cannot dodge them because its raining stones and there is simply too many of them so you will be hit regardless. Having a shield like the knights of westlock aint gonna protect you either as you will still be hit.
Same goes for other zone attacks - the entire zone is struck so there is nowhere to hide.
Forcefield however still surrounds the FM and negates this attack.
That was thematically. Rules wise my first reply in this topic still answers your post.
Regarding the wording for zone attacks they are meant for traits and abilites that work during the avoid attack step.
