Well, this is supposed to be made for units that have higher skill than speed. Units like Leonardo can usually benefit from this more than Adept. It will make Killing weapons very good, anyways. ~30 Crit*2.5 = 75% chance of making your Killer weapon brave. It's also compatible with Brave weapons, so it will allow you to have 8 hits. If you put it on Zihark or Soren, innate Adept, then they can possibly get 12 hits.
