Bluta will cast an area greater dispel magic, centered at 100N35E15Z. That should have Maximus Rex and the center of the daylight at 95N40E in its effect, along with portions of other daylight spells.
In that case, Bluta will swim out of the water straight up, fly just above the surface of the Victory Zone, and splash down at 100N80E, and swim down to 100N80E-20Z. Along the flight (and once past the area of effect), Bluta will cast the spell in the same location as noted in my last post.
I thought it was only for fire spells or spells with attack rolls.
Edit: Rules question: If Bluta travels along her path, it seems Max and OS will get their readied actions (tail slaps). I don't know if they get AoO's. Bluta is 'visible' while in the water, but the part of her in the water does not provoke an AoO (although out of reach anyway). When Bluta is half-in/half-out, the half-out part shouldn't provoke, right? Even though they can otherwise 'see' her water-based half? No, I'm not saying blindsense allows them an AoO either. Although, you should roll miss-chance on the readied attacks (OS has blind-fight). If either get an AoO, though, it will be with a trip.
