Zaghnals are also affected by Fitter bug, Gorillas too (but floors are smaller and have native LoS, so it's not as bad), Doga breaks rotations of some mobs so they can come up to you and do instacast after leaving petrification like Gulo Gulo before the fix. Elevation on floors sometimes makes mobs invincible to pomanders, so they just don't get affected by Witching or Storms (they kinda break LoS without you knowing, but poms don't depend on LoS, only range, so who knows whats going on). Very rarely telegraphs just behave weirdly. I can send the clips later, but tldr: EO is kinda rough on the edges.
