After you enter the room, turn into Mist form and fly past him as he gets up. Hover on the wall behind him, just above the middle ledge. Wait for his attack to end then come out of Mist form as he finished Turning. You will land on the middle ledge and will be in perfect striking distance with his face. Repeatedly press [Attack]. Continue to hit him until Galamoth is dead.
Note: This trick may only work with the "Start with 99 luck" code enabled. In the room before you encounter Death, there are three giant wolves called Wargs.

Leave the Alucard Sword, Necklace of J, and Twilight Cloak equipped. Make sure Alucard is looking left. Allow the Warg to hit Alucard, and he should fly out of the room through the door on the right, then fly through across the room with Death into the next room. Do not enter that room until you defeat the first Bosses or after that.

After using this trick, you can access a hidden save room. Go towards the drawbridge and you will fall into a hole that leads to an underground cavern. Go to the right to access the save room.
Use the "Walk through walls" glitch at the first area (the one with the drawbridge) and fall below the map. Go towards the drawbridge and you will fall into a hole leading to an underground cavern. There are only two ways to go; up, which leads back to the main floor, or right, which takes you to a glitched save point which does work.

He can perform a super jump, a blade charging move, and use secondary weapons such as the throwing dagger, axe, and holy water.
