I think the plan isn't as effective as just mentally forcing them to attack/eat each other with a reliable melee guard on the casters.
I am not done yet, and we didn't master or even learn a domination spell. I think issuing a command for them to turn on each other is outside of our reach at the moment... or is it?
Your biggest problem will be protecting Derryth and Thaïs since they will need to sneak up the ramp to cast compulsion and you will have to almost immediately draw out the other Blues or they may try and stop their dominated friends. This means that as soon as the Blues see you, you will have to break the link and run for it with Tyrvard covering your back. Also since you probably will not be able to catch all of them in the blast you will also in all likelihood have to attack up the ramp and into the room to make sure none of them try to flee by opening the front door. There are some risks involved such as being cut off or overwhelmed but it could succeed.
All right, but what I want to know, is the risk of being overwhelmed higher or lower than in E, which has us doing the same thing (engaging all 20 of them) in an open terrain without a big ace up our sleeve? Gareth's opinion.
Furthermore, let's assess our melee fighters. We have Tyrvard, Gareth, Jory, one of the shielddwarves, Ithapi (is he in fighting shape? It was mentioned he would take ~2 days to heal, but we took our sweet time getting here, about a day and a half). What about the pathfinders? They are ranged cocktail throwers, right?
I think it is a bit of a waste to sling direct damage spells outright if we go with the bomb. Let the bomb explode, then pick off the survivors with all the means at your disposal. What the mages
can do is crowd control. Derryth could attempt a mass suggestion that Tyrvard is the tastiest of the bunch and they all should chase him. It should be easier since they already consider him an enemy and already want to do so to a degree. Does this have a good chance of success? Thais and Brigit can use Create Fire on the battlefield to create bottlenecks and organize the enemy rows in a way that would be best for our team (Brigit does have oil for that Fire Arrow of hers, or does she rely on magic?). All of them can make simple suggestions on the stragglers as to what path is better to take and whom to pursue, so that the bomb would have maximum effect.
I am just throwing out suggestions here.
What we sacrifice, compared to E:
A satchel charge
An advangtage of fighting smaller groups one at a time (though I think we will still be surrounded at the gates)
Direct damage spells
What we gain:
We don't have to control the gates ourselves and can choose our battlefield
The bomb should compensate for the lack of ranged damage provided that the mages put more effort in crowd control to maximize its effectiveness
I think being a bit more strategic about it and investing some resourses should give us an edge.
