I'm wondering if anyone here knows what makes certain PvE attacks dodge-able by sets like Merdia or Shadow Dancer. A quick test in Wayrest 1 shows that only some of the "yellow" attacks from bosses can be dodged with these effects, even though most of them are single-target "heavy attack" type hits. Of course, dodge rolling works as expected and negates all of these attacks. Are there any definitive qualifiers for what can and cannot be dodged?
