It's intended for bullets, but it would work for any projectile that fits within the panels. It would make it effective against any physical weapon, which is what most of the people here utilize.

Maximum capable size is a 15 meter diameter, thoooough it would be difficult to set it up at those specs, heh... For Freeze Lattice, I'll need more information about the ability. Freeze Lattice's skill range should be capable of freezing anything that comes in contact with the Lattice. If you were to be caught into it, you would be rendered incapable for a period of up to 5 minutes. It was designed to be a means of escape.
