Omnislash
Cloud’s Level 4 technique hits random enemies 15 times, with automatic critical hits for three-quarters normal damage per hit.
How it works
Omnislash is taught by using its manual after Cloud has obtained his other six Limit Break commands. Its listed effect is 15 hits on random enemies, each under automatic critical hits and dealing 0.75 times normal damage. More generally, the source says a Level 4 technique is taught by a manual only after the character learns all other Limit Breaks.
