Incidentally it takes two summons of KOTOR to take out Safer Sephiroth, so it’s still not enough to take him out in ‘one shot’.
I think I’ve always used it to defeat Sephiroth, but after he’s done his nova thing…
I personally do not cheat anymore, as I want to beat the game all by myself. This made me play one level in one game more than a dozen times, and it made the joy of finally beating the level great! But I don’t judge on people who use cheats. So using Knights of the Round, which is a legal option, it not cheating for me. However, I dare you to try and beat the game without them 😉 If you like the game, this will be a nice challenge!
Use that summon to your heart’s content.
