Okay, this probably going to get me yelled at by several people, but I just had a thought—could we do Druchii diplomacy actions as WEB-MAT action with Egrimm.
He's the same rank as us, has similar intrigue and diplomacy to us, is fairly flexible in his morals—especially if we frame it as exploiting and stealing from the Druchii—and it would be an interesting show of force to send two high ranked mages, one light, one grey, to these negotiations.
Combine it with the Deceiver coin, and trick the Druchii into giving up more than they intended too, only to swing over to the Asur and demand a counteroffer (preferably one that includes Teclis and the ability to persist with the Waystone project).
Best of all, as a WEB-MAT action, it's AP efficient.
also we get to scare Egrimm quest with our spooky grey wizard back room deals
