Yeah, not too much on tattoos there but thank you for the help anyway. I really don't want to break rules, not my thing, so... what if I just post my idea and get some feedback on if it's going too far.

Imagine a girl in a dwindling group of survivors who suddenly finds herself the last person worth a damn for fighting. She also finds herself in possession of a substantial amount of Dust. But she lacks the ability to create the kind of high class weapons hunters use, in fact the weapons available are overall 'not great.' Solution: put Dust into tattoos for more power behind those weapons. Result: weapons consistently break putting herself and others in greater danger. New solution: become the weapon. She sews small crystals into her body, adds extensive Dust infused tattoos, and creates vials of Dust diluted by water. She tried consuming pure Dust but that was extremely painful and wrecked her digestive system. Even the diluted form continues to aggravate the damage. New Result: she gained enough physical speed, strength, and durability to go one on one with many kinds of Grimm and rip them apart with her bare hands.

So, yeah. I feel my idea could really be pushing or surpassing reasonable limits.
