Item description:

After loading the save, select "yes" to continue. You will be in a hallway before a boss as Maria, collect the candles and
whatever item if you want. When fighting the boss, stand at the top left, (where you entered the boss room), and spam
the normal attack with jumping and items if needed to defeat the skull and ghost. Spamming square you will kill it in literally seconds.
Just don't let the woman grab you and drain your hearts down below.
Then attack the woman and just let her jump around from side to side as you hit her each time until she dies.
The next stage will load after grabbing the orb and then congrats, 100% completion and the Full Belmonty!

Tip: If somehow you are about to die to this simple boss, quickly pause the game and select quick save,
this will let you go back to the main menu and select yes again, and you will be back in the room before the boss fight again without
losing any lives at all.
