with two of your characters dead and cloud with a full limit bar:
1. omnislash on the tentacles.
2. w-summon:
mp-turbo pheonix first, then mp-turbo hades.
3. enemy skill- pandora's box
4. w-summon:
mp-turbo hades, mp-turbo hades.
5. repeat step 3 first, then repeat step 4.
if ruby does any move except retract his tentacles one time, or if you hit ruby with kotr, you're not doing it right.
suggestions are welcome, especially qhimm.
