Re: Forging a Path
Once Ilura got the birds dislodged from her beak, the unintentional passengers spiraled slowly toward the ground, screeching obscenities at the ranger. Their injuries were not life-threatening, but they were bad enough to make flying difficult for the sea buzzards. The rest of the flock, however, continued to follow on Ilura's heels, more determined than ever to catch her.
Meanwhile, Eryn and Mouse prepared to face down the last of the pelicans on the ground. As they waddled around the dead queen, they screeched and flapped their wings aggressively. There were even still a few shell fragments stuck to some of their feathers. With a few deft foot movements, Mouse got into a position where one arrow could pierce two of them at once.
Thwak!
The arrow pierced through one, then another, and finally pinned both to the dead queen's belly. The other four birds continued to advance, but then suddenly paused. They looked back at their queen for a moment before hastily taking flight, up and away in a panic. Where the arrow had struck, a small stream of green liquid spouted, coating the freshly killed sea buzzards. Where the liquid touched, their feathers quickly melted away, followed by flesh, and then even bone. A horrible acrid stench filled the air, masking even Eryn's delicious aroma. It seemed the queen buzzard's flesh was being affected by this fountain of acid as well. The hole where the arrow had struck rapidly expanded and a surge of acid rushed straight toward Mouse and Eryn!
What do you do?
Ilura
The flock is still following you. As for casting spells, the way the rules are written I don't see why you wouldn't be able to cast spells. The only reason she couldn't would be for flavor reasons. I will leave the final decision up to you though. If you think Ilura would be able to, you can. Just make sure to describe how.
Mouse and Eryn
There is a surge of acid rushing toward the two of you out of the queen sea buzzard's stomach. Eryn can easily step out of the way if she wishes with her longer legs, but Mouse is in a more direct path and will have a slightly more difficult time avoiding it. Probably a Defy Danger for Mouse. Eryn too, if she stays to Defend Mouse.
