Well, the first draft of the plan (a variant of running retreat as per Dii, let it be called Div or something):
- Send the child into the Dreaming. Morpheus (I'll just call him that, since Lyssa thinks that's his name) said that if we send him living beings, he'll send back his elves and fairies. He promised us power and information. As far as the gifts go, this one is quite generous, so he might even come in person. He might know how to fight these creatures, or he might provide us with direct support. We don't know what he can do, but if he ever wants to receive more 'gifts', he'll have to do something to get us out of here.
- Scatter our people just a little bit so that we don't bunch up and get trapped in the yellow substance as a group, but not too far apart that one would not be able to help the other if something happens.
- Hit the creature with everything we've got. Have our archers, and even spell-casting mice (why the hell not, if the range permits?), aim for the heads or the eyes. Hopefully, it does feel pain just as we humans do, and it might overwhelm it and make it unable to react. Or maybe we can one-shot it with the Greater Energy Bolt which, apparently, is still stored in Thais' ring.
- Astrid's flash grenades might come in handy if the creatures rely on sight. We might want to check that.
- Break the locks with the Warrior's Mask. Or just rip the chains out of the wall. We don't have minutes to pick them, we must hurry and flee before the other creatures pour through. We must do it fast, and it is the next fastest thing after C.
- Redistribute the energon cubes, if necessary.
- Have the dwarves drop the satchel charges as they retreat. If the creatures do get through, we'll have to detonate those to cover our flight. Try to blow up the creatures, not the tunnels.
- If anyone gets caught in the sap, try to break them out with the Warrior's Mask. Either apply it to them directly, or to the one trying to dig them out, depending on who is stronger.
- The mages can help in a variety of ways, but that would depend on what kind of support we'll get from Morpheus. It's hard to theorize beforehand.
- Send our people through the fissure. A scout should go first, the kids and the wounded go right after them. The mages should not go last, but they should not evacuate quickly, either, as they are the ones who can hope to keep the creatures at bay. Hopefully, Morpheus can cover those who will go last, as he does not belong to the material world and thus isn't risking much.
Anyone wants to add anything?
