Great lord of the Ninja abyss, I summon you!
Revision to greater fireball -> Ballblast.(Recall that the streamlined spells were streamlined to be small, they cut out a lot of stuff that was holdovers of being big. Revising them to ebe big again may involve taking out the streamlining...)
Heat is a problem, remove heat. We know that they burst when they reach the target, so just focus all of the energy on that and create a force-based ball instead of a fire-based ball. This should be a better companion to the smaller fireballs as it offers something different, being able to break hulls instead of burning them and burst trees into splinters instead of fighting the frost and rain constantly.
Also make sure it isn't a national effort, we want them to actually be fielded.
Revision to Myark -> Myark's apprentice.
Myark gets an apprentice that enhances his ability to win duels to the point that Al can potentially be defeated even if our forces are at a disadvantage, thus driving the maniac away for a turn. Can be further revised into an addition hero.
Revision to antimagic charms and antimagic bombs -> quartz growth
As part of the initial design document of the bombs, it is hoped that we have some research in magically growing quartz. If we can get it working we can increase the supply, allowing us to at least equip all of our commanders and wizard-hunters with them.
Revision to antimagic bombs -> Antimagic bombs
Give them the ability to shatter to cover an area in antimagic, rather than the largely redundant ability to burst into an explosion of flame(the theory of trading duration for area doesn't seem too far fetched as a means of miniaturising the charms.). Also include some nifty quartz-growing magic to justify it being a design rather than just a revision of our old flawed charms into an arrowhead.
Orders
test their antimagic: We need to figure out what exactly we are trying to counter.
Use channelled fog:
We tried to train with frogs, it was chaotic and mad, which is very similar to fighting in fog. The survivors of the frog training go into battle under cover of fog. If it vanishes, then we know that the channelling effect does not resist their antimagic.
Use crystal weapons which are protected by antimagic:
This should have happened in the initial engagement but we have no data on it. presumably it does nothing, but we need to know. Equip a group with both antimagic and crystal weapons(AND backup weapons) and have them carry caltrops. If the antimagic charms can't even protect caltrops which are completely immersed in the charm's effect then we know.
Interviews:
Get some survivors from the crystal weapon disaster, what specifically happened to the weapons. We heard they just vanished, no breaking down, just poof, gone. Is this true, because that is a crazy difficult effect to undermine. No amount of stability or hardness can stop instantly being unmade.
Get some wizards who have had their spellcasting disrupted. Did it vanish? Did it bend? Could they not feed it? Was there too much to control... Describe it in detail.
BOMBS:
Give our wizard-hunters some antimagic charms. No magic = the bombs are safe. Kind of all in the original design document but hey, doesn't hurt to check.
