Sacrificial summons: Frost Vulture Aviary Program
A farm for frost eagles to be summoned, bred, trained, and sent to the front.
Learning from our wasps, we knew that to defeat a wind spell would require something more hefty. Learning from our crystal weapons, we knew that we would require something more mundane. But we also learned many positive things as well. We knew that combining life with the elements could be effective. We knew that magical materials could exceed mundane, and we knew that life could be brought forth from nothing.
To address the antimagic issue, we needed to conjure items that would no longer Be promptly dispelled. We addressed this with new Sacrifice Circuits(S.C.) that can drain a quantity of material and metamaterial into the circuit to feed a spell that promptly uses the sudden absence of material to summon a stable entity. In this case, a quantity of meat for living tissue and cheap gemstones for crystal materials, along with a frost-imbued and crystal-imbued magical artefacts(Strips of metal with circuits of inconsequential versions of these spell schools with which we are very familiar) for the relevant magical essences, a life(typically vermin, either a rodent from a store-house or a pest captured from the battle-field) to grant vitality, and a very large quantity of invoked magic, to make up the necessary force of the effects involved.
To address the wind issue, we sought out a high-altitude creature of extreme proportions. We found a vulture that flew so high that they normally couldn't be seen. It was a metre long with a wingspan of two and a half metres. We needed more, we doubled its size in every dimension, and then added 50% to its wingspan. We then looked to the mystical options. We added to the new creature naturally-growing crystal veins along its bones, talons, beak, and the trunks of their feathers. Then funneled cold magic to have them absorb cold into their crstalline growths, keeping the bird warm and causing an explosion of cold when a vulture dies and a small burst of cold if its crystals break. Finally, we used trial and error with the early prototypes to make them a more "powerful" and "healthy" and "intelligent" animal by magical mandate(magicdate? manical? umm, mangical? er... no...), to allow them to function with these alterations and be capable combatants.
Training them seemed to be a simple matter of launching Kegger carpets and uniforms in the general direction of their nests while Arstotzkans attack the crude catapults to win their favour. Additionally, being newly created they have little choice but to accept their summoners as family. Being summoned as adults has very much helped to accelerate the breeding program...
Summon Giant Fire-wasps.
Fire wasps, five-metres long, thick carapace, doesn't care about insect-breathing-mechanics or flight capability because "a wizard did it"...
Tall Frost towers
We use our abundant metal supplies to strengthen the frost towers, allowing them to be taller, thinner, larger, and have a concave shape without requiring more material or being weaker. They provide spotting for our artillery and have been modified to revert back to some of the fire-ball roots from which they emerged, being able to propel the same chilling effect as ball spells, essentially moving their point-of-origin forwards, or right into the middle of an already-freezing aerial kegger group. Given the already massive scale of the Forever Frost towers, this easily exceeds our fireballs in range just through brute-force.
