Very interesting and entertaining looking concept, so I'm interested in joining if you'll have me. I have an idea for magic already but I would prefer you to give it an all clear before I build a character around it, so here it is:

[Hider=Paper God Magic][b]Magic:[/b] Paper God Magic is the ability to freely manipulate sheets of paper through the will of the user to form a wide variety of shapes and forms. The more skilled the user the more complicated and intricate the shapes that can be formed. Paper that is being manipulated is far more durable and resistant to damage than conventional paper and is as strong as any steel while Paper God Magic flows through it. Basic practitioners of this magic use it to form small weapons and shields, more advanced practitioners have a far more varied repertoire of techniques as their disposal. 

The greatest weakness of Paper God Magic is that of fire, regardless of whether the fire is magical or natural in origin, though natural fire needs to burn far hotter to destroy than magical fire to inflict the same degree of damage. Paper that has been soaked is also an issue for practitioners of this form of magic as it becomes more difficult to wield. However paper that is already being manipulated can only be drenched by the use of magical imbued water. Rain water and the like is not sufficient. As distance from the caster increases so does the difficulty in maintaining control of any manipulated units of paper, preventing effective long range attacks and limiting the effective range of the magic to medium range at most.

[b]Elemental Affinity – Paper God Magic[/b]
[b]Fire[/b] – Very Weak
[b]Water[/b] – Weak
[b]Earth[/b] – Resistant
[b]Lightning[/b] – Resistant 
[b]Wind[/b] – Resistant
[b]Light[/b] – Neutral
[b]Darkness[/b] – Neutral[/hider]

Don't hesitate to tell me if anything is OP or needs changing.
