[@Dead Cruiser] Hoo boy, where do I start? Yeah, your character is definitely way too overpowered at this point for the RP. You'd have to make a lot of changes to his spells. Thematically, his spells just include a bunch of niches. He has necromancy, support spells, alchemy, elemental attacks, and even future sight. It's too much. Here's what I would need to see changed:

[hider]AWAKEN THE DEAD
Sekhandur can compel a corpse to do his bidding. Either briefly rousing it to answer his questions, or reanimating it entirely. He may raise a body as a simple, shambling undead, [s]a Nenitu with an infectious bite, or can infuse a ghost into a corpse and create a revenant. This spell can achieve true resurrection with greater mastery, but Sekhandur has yet to achieve this feat.[/s]

CTHONIC DOMINION
The incorporeal undead are also Sekhandur's to command. With this spell he may reveal the ghosts in an area, render them vulnerable to physical harm, bind them to his will, swallow them to consume their mana, [s]torment them into madness, or infuse them with the darkness of the underworld to twist them into malevolent Cthonic Beasts.[/s]

GIFT OF THE GOD-KING
Unleashing the majesty of his divine soul, Sekhandur can [s]inspire others to feats of bravery, restore his allies' willpower, cure sickness, dispel curses, and[/s] even mend wounds and injuries.

HARVEST OF THE DIVINE
[s]Sekhandur can transmute mundane materials to gemstones and precious metals, primarily gold. This process is irreversible, and does not work on enchanted objects, but he can also choose to render these transformed materials into dust. This spell can be used on living flesh, including the king's own, transforming them into an invincible golden avatar, but Sekhandur has yet to achieve these feats.[/s] Your own flesh is okay but the rest of this isn't.

[s]KISS OF CHAOS
Invoking the Cthonic darkness, Sekhandur can poison his foes with necrotic energy, invoke a deadly curse upon them, or summon a cloud of darkness that attacks his enemies and drives them mad.[/s] Just more OPness this character doesn't need right now.

POWER OF THE SKY THRONE
[s]Sekhandur can create magical flames that speak with his voice,[/s] snuff out fire with magical darkness, [s]or compel the sun to burn and blind his enemies with blasts of light.[/s] And even the part that isn't crossed out. What kind of fire are we talking about?

REBUKE THE VIZIER
Sekhandur can shield himself from magic power, [s]set up wards that protect him reflexively, or cast his ward at others to hamper their ability to use magic.[/s] There is also an unspoken rule that you can only shield yourself fully from spells that are below your level. This doesn't need to be included in text but I thought I mentioned it here.

[s]SECRETS[/s] RIPPED FROM SKIES
By staring into the night sky, Sekhandur can divine the his exact location and the hour of night, [s]learn forgotten secrets, divine portents of the future, or summon a meteor to strike where he decides.[/s]

WATER OF LIFE AND DEATH
Sekhandur can summon a spring of fresh, clear water where he stands, which heals and [s]blesses those that imbibe from it. He can also turn nearby sources of water into blood, or part small bodies of water for his passage.[/s] The person in the roster that specializes in water can't even part bodies of water.

WRATHFUL DESERT POWER
Sekhandur commands the essence of the earth. He may scour his foes with blasts of sand, create [s]storms and[/s] dust devils that chase down his enemies like living beasts, [s]assume the form of living dust[/s], create a clay shell to armor himself, [s]or induce a localized earthquake where he stands.[/s][/hider]

And lastly for your mana characteristic, it lists "The humbling magnificence of a billion stars shining in the desert sky." I hope this is just playing it up, but if you're serious then this needs to be changed into something even more humbling (for the prince that is). In it's current state, I can't accept the character, sorry.
