Alright, let's get this started, because 4AM is simply early morning.

Aleyn makes him sound like a girl. Shoulda made him a trap as well. That would help with his assassination. In terms of personality, I'm pretty damn sketchy about the whole 'reading patterns' thing, cause that can go into meta-gaming rather easily. Either that, or lolauto-dodging through everything because you can see thirty seconds into the future and manage everyone's MP to a single percentile.

Are the Sun Slayers magitech? If so, hell naw, because magitech can only have a SINGLE spell, not something as diverse as manipulation of the frickin electromagnetic spectrum. If they are magical artifacts, change the form into something other than a gun, and get rid of the whole 'focusing internal magical energy' thing. For Luna, change the range into something that's actually achieveable for pleb-y Don firearms. Keep in mind that in terms of pure firearms tech, Dons are lower than modern. And 5-10 miles of sniping range is sorta like...eh...more than a little too much, considering I would imagine that being able to snipe from one mile is already pretty OP.Lightning doesn't pierce, by the way, unless you mean a lightning-infused bullet. The sound dampener will only be effective (to a degree) when using physical bullets.

How far does the magical inhibitor go? If the range of Luna is really that retarded, the recoil should do something terrible to his arms as well.

How big are his grenades and how many does he usually carry at once?

Prosthetic Spine invisibility is noplz. Electromagnetic eyeballs or whatever is sorta questionable. Heck, at this point, I'm not even sure people KNOW what the electromagnetic spectrum is, so making spells from something that science peeps don't even know...eh...In terms of the physical boost though, change it so that it's a temporary burst instead of a permanent increase. His muscle structure is still that of a human's, so he'll basically be fucking over his body every time he goes and dodges something that's physically impossible for a human to dodge.

The bullet richocheting thing is plausible, but just keep in mind that they'll generally be small changes in angles, or he'll be using rubber bullets in urban areas. Cause I doubt his bullets would be as powerful if he wants them to start bouncing off surfaces. And, you know, said shots won't happen sometimes depending on the terrain. Oh yea, how does he curve bullets? Note that, ultimately though, he's an assassin. He won't win any type of long fight against a warrior, and I'll expect that he's a naturally fragile person.

Of course, the bigger question would be what he's doing in a battlefield against a MONSTER...

And can someone confirm whether the electromagnetic spectrum actually has anything to do with lightning or raw magical energy?
