Dracula's a pretty tough customer in Castlevania, and if you die while fighting him, you only get very few powerups to fight him again, making things tougher.

But!

You could go back down the staircase leading to his chamber, and then back up again. If you do, the candelabras will reset and you can collect the powerups again. And as long as you don't walk far enough to the left to trigger the boss fight, you can repeat as many times as you want. And using some techniques I discussed earlier, you can really load Simon to the teeth with weaponry

Making this a slightly slower version of the method in Castlevania IV
