Quoted from Mathazar:
Aha, that makes more sense! Sad to say, in 15 or so months of ownership, I have YET to get past Black Castle. I can get there about 1 out of very 5 or 6 games, but I just can't get past it. I will eventually, tho!
Keep going - you'll get there! I've owned my Pro for two years now and only defated Black Castle 4 times. When you consider I've put in over 1800 games, it's not a strong conversion rate
To beat Black castle, I think it's 17 hits on the Pro using default settings (not sure on the prem / le models).
Complete the 3 center targets (flail, knight & shield), which then lights 4 shots (left scoop, left orbit, lock target, right orbit).
Repeat that 4 times (16 hits).
Shield then lifts - hit the VUK behind the shield to complete - (17 hits).
I don't mind a challenging final battle (and Black Castle is one of my favorite battles in the game), but it's more about luck than skill to survive. I've lost count of the times I've drained on the first few shots because of a an unlucky deflection from 1 of the 3 most dangerous shots. Then you have to start all over again... Thanks Tim.
