@Polaris NorthWow! Just wow! This is great Polaris. I like how his name seems like one an Equestrian would have, super appropriate for a reformed human. The picture you picked for his character sheet fits the character and the color scheme of your sheet perfectly!
The green eyes are rather fitting since electrum is sometimes called "Green gold" and in this instance it is vital for his electromancy.
His Electromancy is powerful, but it is largely destructive focused without really much utility to it outside of the Web spell. He needs to be firmly planted to us it, so if he's knocked into deep water where he can't touch the bottom or an enemy keeps knocking him around Lightning won't be able to utilize his namesake. Plus his attacks are largely electrical in nature (save for explosion which is electrically triggered from what I'm guessing).
If he's fighting an enemy with insulated armor or someone who has ground themselves, his attacks won't be very effective.
So while it is destructive it balances itself out by the lack of flexibility. Nice work on the spells by the way, they all seem very relevant and interconnected in a sense. Nothing feels particularly out of place.
Lighting Flash is ACCEPTED!
You may post him in the character section with pride.
