I wonder how did other groups handle dealing with Shealis.
In the groups I ran this is what happened when Buron told them they had to delay Shealis:
Group 1:
"No way! We can do nothing about it, the only thing we can do is go and confront her (talk to her)" (with Diogenes bubble up)
They made the Skill Challenge: Win
Group 2:
"Ok, let's do that"
They stalled a bit trying to figure out how to delay her until they gave up and feeling they had no choice, they confronted her (with Diogenes bubble up)
They made the Skill Challenge: Win
Group 3:
"Ok, let's do that"
They analyzed ways to delay her, and finally they made the crows in front of Gabal's School go mad and having them block the exit of any Gabal student or teacher.
They previously talked to Erdran and managed to get his support and called on the City Guard.
Shealis escaped through the back of the school by levitating and having another professor from the school creating a wind to blow her to the other side (I ruled that she couldn't teleport through the fence because of Gabal's protections)
The party managed to see her and followed her steps through the city undetected.
Once in the Spy's Headquarters they saw her getting in.
They rushed in and tried to take her down.
They failed.
She collected the papers, escaped and they managed to follow her a second time.
Followed her to a house where the tunnel was dug on the basement.
Encounter at the house.
Followed her through the Singing Chasm.
Followed her out of the Chasm, into the mountains, into Shahalesti territory.
Finally she met some Shahalesti soldiers and they abandoned the pursuit.
I'm not sure I handled the last group correctly, since I don't know if something in the next modules would come in conflict with this.
