This was suggested by DJTwisted456, and I greatly appreciate it, really, I do! Anyways, here are the elements-

Water- All Merwolves can use it without being taught, but other wolf types have to be taught. The attack variations are Aqua Blades, Hydro Pumps, Water Guns and Waves.

Fire- All types of wolves can use it if they learn it, but Demon wolves know it automatically. The attacks are Fire Beams, Flame Barriers, Fire Tornadoes, and Explosions.

Nature- All wolves can learn it. Wolvyennas automatically know it. The attacks are Root Whips, Nature Wall, Grass Tangle and Growth.

Air- Angels automatically know it. Other wolves must be taught. Attacks are Flying Strike, Oblivion Wings, Angel Attack and Tornado.

Lightning- Spizhans automatically know it. Others must be taught. The attacks are Lightning Storm, Thunder Strike, Electric Sword and Bolt.

Darkness- All wolves must be taught. The attacks are Darkness Shield, Yin Strike, Raven Attack and Moonbeam.

Light- All wolves must be taught. The attacks are Light Shield, Yang Strike, Dove Attack and Sunbeam.

Undead- All wolves must be taught. The attacks are Dead Protection, Doom Strike, Destruction Beam and Deathhole.

If wolves want to learn these elements, they go to an Elder or the Blank Wolf. Hope you have fun!
