Alright, SMMI, here we go:
Improved Airships: Sure. Worthy of a design, I'd say. If we could bring expense down by not using the carpets and instead enchanting the hulls, we'd be in a good place.
Adamantine: NOT MALLEABLE! We want adjustable properties. Malleability refers to how easy a metal is to hammer into shape. But yes, definitely worth a design and revision. What can't you do with adamantine that is both cheaper, harder, stronger, and hotter/colder?
PDL: Heck no. How is this supposed to stop a cannonball? You're just going to superheat the dumb things and make them even deadlier. Not that they need any HELP doing that...
Eye: How about we start with the modified telepathy spells? Heck, we could revamp our Teletalk to make use of visual communications over long ranges too.
IDDW: Bad idea. I think that that spell has limited further use, and was poorly designed in the first place. I think that we ought to make a form of tower like theirs, capable of calling down continuous lightning around it (INDESTRUCTIBLE MOUNTAIN FORTS YEAH) and warming the air through the constant barrage of plasma. Even if unrealistic, it'd work, because MAGIC, SUCKERS!
First objective: Lightning-repelling enchantments on our men. Applied to entire armies at once by all the mages and apprentices working together, must last at least two days and be 100% effective. Well, 95%, anyway. 1/20 isn't too bad for the GLORIOUS MOSKURGIAN LEGIONS OF MANY MEN.
The lightning-repelling allows our troops to attack directly through the middle of a Hammer strike. Pretty much amazing, terrifying, GLORIOUS, and makes it almost impossible to kill them (Can't shoot if you're fleeing the lightning bolts and crazy horse-riding lunatics of death who are riding through the lightning storm without getting touched). Also, shock value.
