Enjoy your review.

[hider=Myrowyn][hider=Equipment][quote]Deck of Cards (Various have pre-written combat runes on them.)[/quote]
Innue probably said this somewhere, but I need to know how many cards and what runes you have prepared. That or you have to write a post with him in which he is preparing the deck of cards. Also, is each written rune on the card one use, then it has to be rewritten or does he only have to prepare it once and he can continuously use the rune?

The second option is only viable if there is a decent cool down time after a card is used. By decent I mean 30 seconds to 5 minutes depending on the strength of the rune.

How far away can you write a "rune"?[/hider]
[hider=Jutsu][quote]Seal: Rift
Effect: This sealing rune has a myriad of uses, the most common being a means of transportation. By connecting the rift with a pathing phrase, two-way portals can be created between long distances. An initial sum of energy is required to write the rune, it doesn’t feed on a continuous supply, however it will deactivate after a day. If a path rune is not written, the rift will lead to a ‘void pocket,’ which has no gravity or air, the void can be used as a deadly trap to anyone without any anchoring abilities.[/quote]
So you being able to keep a "rune," activate without it requiring any energy source is not okay. If you're saying it requires a set amount of energy to write (activate) and then that energy sustains it, that's fine. However, unless you're using a large portion of chakra, then it's not going to last anywhere near as long as a day. Sorry.

[quote]Seal: Leech
Effect: This seal is simple and deadly, for once it is written on a person, it will gradually begin to sap them of their spiritual and physical energies, trapping that chakra in to the seal’s written word. The leech seal can only extract chakra that passes within its boundaries, however, and thus cannot sap anyone dry without being written on one’s palms or head.[/quote]
So...chakra circulates through the entire chakra system when it's not being used. So applying a leech seal would actually be capable of absorbing all of their chakra. Also, placing it on the head wouldn't do it fastest and neither would doing it on the palm. Placing it on the belly or over their heart would drain the fastest as that is where the chakra pool and the central "pump" for chakra is. How fast would the seal, at max speed, drain a person with average shinobi chakra?

[quote]Glyph: Divide 
Effect: Strangely named, this glyph is actually the most powerful defensive spell among Myrowyn’s arsenal. It requires a circle to be drawn around the rune, which would then divide everything within the squared circumference of the rune from what’s outside. The ‘division’ comes in the form of an invisible barrier that cannot be breached by the corporeal. A weak point in this barrier exists exactly at the base of the barrier, where the rune is written, enough strikes from a powerful attack will break the barrier at this spot.[/quote]
How much punishment are we talking in terms of this barrier failing? How many D-S rank techniques can it withstand? What about techniques which disrupt chakra in various ways?

[quote]Glyph: Gravity
Effect: This rune word means exactly what it controls, gravity. If written face-up, it will suck in everything it faces directly, with extreme pressure at close range. Treading the vacuum will make any man feel ten times heavier than they actually are. If written in an inverted fashion, the rune will negate gravity, creating a powerful anti-pressure capable of lifting grown armoured men high off the ground in an instant.[/quote]
I'm going to deny this. Not because it's OP on its own, but because I feel Myrowyn is capable of too many seperate things that in combination will easily merc a great many.

[quote]Glyph: One
Effect: Once written, this rune will attune itself to its surroundings. Writing the rune is simple, and there is a trick to expanding it at will. Anyone who stands at the very center of this rune will feel as if they are one with the world, allowing greater perception of an area, or better meditation circumstances.[/quote]
How great is the attunement to their surroundings?

How exactly does this technique work mechanically speaking?

[quote]Idiom: Ignorance is Bliss
Effect: This combination of Ecstasy, and Leech runes creates a powerful idiom when properly pathed, capable of turning your brightest pupil in to a vegetable in minutes. If written on the spine, neck, or head, this idiom will sap the victim of their ability to process new memories or thoughts properly. The simple effect? Short term memory loss, until the idiom is lifted.[/quote]
So to be clear the effects of this ability are entirely temporary unless the rune remains on the person?

[quote]Idiom: Time-Space Paradox
Effect: Wither time, erode gravity, divide from reality, and what do you get? The time and space altering rune, which can speed up or slow down time within its field of control, depending on what order its supplementary runes are arranged in. At its peak, it can amplify the speed of a dagger to pierce through high grade armours, or slow that item down to a fifth of its initial speed.[/quote]
Denied.

[quote]Idiom: Beacon of Nihil
Effect: Amplify gravity, and erode everything caught. This idiom is by far the most dangerous in speedy combat, for the minute it is unsealed, a powerful material-disintegrating beam of pure energy will be let loose in the facing direction. The beam will last for a second, maybe two, before the rune itself will evaporate. The laser beam can eat through metal with ease, and annihilate flesh instantly if caught within the first fifty feet, beyond that will leave searing burns, that are just as lethal if not immediately treated. Variants of the beacon explode on contact with anything it cannot erode.[/quote]
I told you to remove the gravity rune, so I doubt this will still work. If it does, lower that from fifty feet to a 15 foot radius around it. anything outside of 25 feet will only be uncomfortably warm.

That is if you can make this work without gravity.

[quote]Idiom: Nowhere of Importance
Effect: Combine a pressure space, nullified, and altered to only leech from a vicinity, and you wind up with an anti-magic area of effect ability. The rune itself is immune to most nullification, thus saving from self-disruption, while fully disabling any and all chakra based manipulation within its boundaries. Merely standing within the area can be dangerous, as it starts to block and sap its victims of their energies.[/quote]
So this nullifies energy manipulation by absorbing energy and it can do this even if the energy is in your body. That's not okay. This rune should have a medium chakra cost (A rank) to last for a set amount of time, maybe 1.5 minutes. It will only sap a miniscule amount of chakra that is in a person's body, but will sap anything outside of them fast enough to disperse anything but A or S rank techniques or specialized shit.

[quote]Idiom: Fountain of Youth
Effect: A complex and advanced variant of the time-space paradox idiom, this rune phrase created an area of focused power, where time is completely reverted, rather than slowed down or sped up. Requiring a lot of energy to sustain, this technique can be used to heal wounds that are otherwise impossible to remedy any other way. The Fountain of Youth cannot heal any injury dealt over a few days prior.[/quote]
Once a day. High chakra cost.

[quote]Donning The Silver Armour[/quote]
More than the two things you mention can harm this armor. They won't be terribly common things, but I feel the need to tell you that.

[quote]Clear as Water[/quote]
I'm fine with his own invisibility, I'm not fine with him making the silver water invisible.

[quote]Mirror Clone[/quote]
Should require chakra to reactivate. Also, why is it impossible to tell if it's really Myrowyn or not? You can't just say that and assume I'll not ask you how it is achieved.

[quote]Mapping the Landscape[/quote]
He should be incapable of turning a given substance from one form to another (he can't turn earth to sand or earth to stone and vice versa etc etc). He should have limited use of other techniques while in use. I presume that is the case since it'd be harder to make his runes or use handseals when his palm is on the ground, but still.

[quote]Rise, Golem Army![/quote]
Chakra intensive. Should have a time limit if you want to use it continuously. The golems are not intelligent like clones are.[/hider][/hider]
