Castlevania Advance Collection

This has both Boss Rush Modes from the compilation. Skip close to the end to see how to beat Graham.

He has three phases during this boss fight. His first phase is very similar to most games' Dracula first phase. His second phase is where those powerful projectiles comes out circling around the screen. If you pay close attention you can easily get around them to continue attacking him.

The last phase he has two main attacks. There's the moving piece that will attempt to shock you. The good news is you will have enough time to avoid. Of course that also depends on the hands.

When you see either or both hands shine for a few seconds. Quickly prepare to duck, hopefully you don't get shock or hit in a way. You may get stuck to getting killed fast.

For the first two phases aim for his head. For the last phase aim for the middle. I also recommend bringing a lot of health items. In Boss Rush Mode, you don't have em except when you defeat bosses to collect their orbs.

I would say he's harder than Chaos in comparison. The only boss I had more trouble with was Julius Belmont. Otherwise take your time to learn his attack patterns.
