The Castle Abilities Include:
Reality Warping (The Castle does not work on standard logic, where changing rooms can have one view a completely different background[89], such as room with a blue sky that is reflecting up and downwards and having the clouds rotate at a fast speed[90]), Transmutation (Beings that come near are subject to the castle's influence, such as a local barnyard owl which was mutated just from flying near it[91]), Possession (The castle possesses objects with its magic, such as a ouija table[92]), Sealing (Dracula's magic captured Aguni, a primitive god of fire[93]. The Castle has doors sealed off without solving puzzles[94]. This can extend to walls being sealed off where explosions will not affect it until the seal is gone[95]), Mind Manipulation (Everything that enters the castle is under the control by the power of Dracula's castle[96], the ghost of Eric Lecarde needed to cast a magic barrier to bind himself so he could be free from the control of the castle[97]. The Castle corrupts the minds of those who enter it, such as making Maxim Kischine feel strange ever since coming to it[98]. It also corrupted the mind of Hugh turning him against Nathan with Nathan noting he's being controlled by Dracula[99]. The castle increases one's dark desires, allowing Dracula to easily control them[100]. The magic of Dracula's power that empowers the owl enemy also spurs it to violence[101]), Madness Manipulation (The Castle warped Gergoth, a once-gentle beast and drove it mad[102]), Size Manipulation (Magically enlarged a toad through the use of demonic baptism[103]), Fear Manipulation (Even while far away, Curtis and Michelle felt malicious intent from the castle where their bodies seemed to squeal "run away"[104]. Michelle even being at the entrance to the castle had her body telling her to not go in and her leg muscles being petrified like stone[105]), Curse Manipulation (The Curse status that spirits inflict[106] comes from them absorbing the magic power around the castle. The Castle cursed a human to turn into a lizard man[107]), Life Manipulation (The castle can bring inanimate statues to life to attack[108]. Can cause the glass murals to come to life and attack[109]), Soul Manipulation (Those that die in the castle become one of the floating spirits that wander the halls of the castle for eternity[110]), Abstract Manipulation & Hell Manipulation (The castle can create a core of evil made from hatred, envy, anger and other dark emotions[111]), Text Manipulation & Plot Manipulation (The vital souls are noted to be apart of the Castle's power[112], where is noted by Lucy that the "vital soul" of a monster is the cause of the grimoire chaos[113] where creatures of the night's dark powers allowed them to rewrite the Grimoires to strengthen their dark powers greatly[114], along with their vital souls causing the grimoires contents to be overwritten changing history to things such as Jonathan Morris is now at a disadvantage in battle[115], or Charlotte fading from existence due to them messing with the history of the Grimoires[116], Maria starting to fade because Richter's history is being rewritten[117], where if the contents of the book change the creatures magic will keep growing and eventually overflow into reality, causing the grimoire to fall into chaos and even more monsters materializing into the real world[118]. The text alterations also make the monsters stronger[119]. With the real world and world of grimoires being one and the same[120], compared to the like of Brauner's painting worlds that are quantum multi-layered spaces requiring understandings of theories such as "Curse Amplification"[121]. Death was going to use Dracula's magic to rewrite Dracula's defeat to Trevor making it where Dracula defeats Trevor Belmont instead where Dracula would go on living in the rewritten grimoire with each grimoire being its own world and the grimoires influence extends into reality[122]), Law Manipulation (The vital souls are noted to be apart of the Castle's power[123], which alter grimoires, which do not adhere to the laws of reality[124]), Power Modification (The vital souls are noted to be apart of the Castle's power[125], which the vital souls cause alterations of the Grimoire that can greatly limit the powers of those far stronger than them, such as Jonathan Morris' power being limited due to the alterations[126]. The Chaos of the Grimoire destabilized the magic of the others[127])All previous powers and abilities, Undead Physiology (Eric Lecarde was able to retain his consciousness after dying, existing as a ghost to help Jonathan and Charlotte[128])
