Nahobino, fought the fallen he started to buff himself. Then Satan asked, Are you the Strongest Nahobino because you have God's Knowledge or do you have God's Knowledge because you're the strongest Nahobino? Young Man simply answered. Nah, I'd Win.
I just did this strategy yesterday night. I wanted to see how busted chaotic will was, and yea Satan just summons his allies over and over till he dies. Pretty sad, demi fiend is also very susceptible to this particular strategy. Chaotic will is seriously strong, but it wouldn't be as effective without Masakado, because his unique will kill most allies by the time he casts it a second time.
Shiva’s innate skill reduces the MP cost of skills if the user has a charge effect (you can see this at 2:29 and 3:09. Shiva’s Donum Gladi goes from 23 MP to 19 MP). Though, I mostly did it to screw around as I didn’t really need those actions.
