Unknown to most, but 'INEFFECTIVE' was originally Cloud's second 1st level limit break, replacing 'CROSS-SLASH.' In a wild frenzy, Cloud would slash and slice his sword, adding up about 10,000 damage at early levels. The Catch-22 is that he always attacks a monster that's already dead, so that 10,000+ damage is, hence the name, ineffective. Needless to say, this limit break was removed from the final version.
