got two more ideas. What about a semblance that deflects attacks. However the amount of aura needed to deflect attacks would depend on the kleves. If someone like Penny went "Imma firin mah LAZAR!" then Liadan wouldn't be able to due to its destructive capability. But for someone like Roman with his blasts of dust form the cane, she would be able to Deflect/Block it with relative ease. But like mentioned the power in the attack will have to match the power of the barrier for it to work. IT can even work against Grimm.

Also, what about a semblance that does accelerted healing. Powerful enough to save a person from a life threatening wound, like a stab to the side or a bullet through the chest....so long as the bullet passes through the chest and not the heart.

However this doesn't make him/her invincible; all it does is give them an edge in a fight, s/he can still die from shock if their limbs are cut off, and the healing won't be able to restore their limb, but seals the wound in the place. Its not a form of regeneration, more like a sealing of wounds as scars do remain.
