Cilyne is a flesh caster. That means that she stores her magic in her skin. It has its benefits and its downsides but for her it works. This is her current tattoo chart at level 12 in her elemental abilities. The tattoos are for her magic the piercings are for her faith.
I chose to use individual tattoos for each level because with all the other things she spends xp on she is not going to run out of space for them, plus then i could design a bunch of different tattoos for her and I didn't have to stick to one theme if i didn't want to.
