Unduism

Unduism is the next step beyond Procellamancy, and the most advanced verison of elemental storm magic. Generally used by the mages of Zavak, this is one of the two schools of magic still being practiced believed to be stemming from the Dustkiin (the other being Thanatoism).

Air
Unfortunately, there are no cool, new elements resulting from the combination of wind and storm magics. Wind magic can enhance storm magic, making it more precise and powerful. Also, some minor illusions become possible with this combination, which are used by the pirates of Haavermark to create the illusion of harbor lights ahead. To create an illusion you need to double roll along with dex. You must be level 5 storm and level 5 wind to use the strength boost, a double roll is required, and you gain an extra strength roll, independent on whether or not you needed a strength roll initially.

Non-Neutonian fluids:
All the flexibility of water, but solid as rock, and it can carry a charge to electrocute your enemies in addition to ensnaring them. Even a glancing blow can be fatal.

Wires
Solid, unmoving lightning bolts that can shock and rip for days. The user can control what parts of a field are accessible this way, and it is often used by great hunters on the fringe of society.

Pseudo-Brownie swarm:
You create a swarm of little light "fireflies" and charge them all to hell. It's not independent, but can cut, shock, and buffet.

Magnet:
Basically force things to magnetize with such force that you crush the fuck out of them. The ultimate attack is neutron star.

Nerve:
The fastest solid techniques. You create a massive nerve, capable of reacting to movements faster than anything not an Aegerlach of speed, and can whip, carry a charge, or inject Dopamine to calm an adversary

Nova Magic:
Not the same Nova Magic done by going the Air-Fire route, as it uses electromagnetism to create a differnt kind of explosion, but the effects are ultimately the same, as is the lethality to the user.
