This is likely due to the strength of the entities; lore-wise, they are important and powerful antagonists, while game-wise they serve as the most extreme tests of the player's skills, and shouldn't be skipped. There is reason to suspect that the crucifix's design is inspired by Phasmophobia's crucifix due to the similarity in their designs. Crucifixes in biblical stories are known for banishing demons or exorcising them, concluding that the entities are demons of some sort.

Since the crucifix will not affect any entities inside The Rooms, it's recommended to use it before then. There was a problem when using the crucifix on Rush or Ambush when in multiplayer, as the ray-casting of said entities would still kill other players while the entities were getting banished by the crucifix. Using crucifix on Ambush is effective if there are not enough closets or if a player is unexperienced. Using a crucifix on Rush is only useful if all closets are taken or a double-rush occurs in the Greenhouse.Under federal law, if you knowingly misrepresent that online material is infringing, you may be subject to criminal prosecution for perjury and civil penalties, including monetary damages, court costs, and attorneys’ fees.

In the sigil's inner circle is a message in the font "WingDings", a font that displays letters as symbols. It can also be found in containers, mounted on bedroom walls, suspended over doors, inside chests, and on tables.However, once one is skilled enough to avoid them, it is not worth it to use the crucifix anymore against them, unless the player is speedrunning. This also applies even if the crucifix is failing to work, though the chains eventually glow red and break.

This is actually because when they watch Seek being banished, the chase is still ongoing, multiple doors have been opened, and they have been teleported by Void. When equipped and held out when an entity attacks the player, the crucifix will chain the entity and stop it in its tracks. Using crucifix on Seek can be useful in 2023 April Fools Event or if the player runs in the wrong direction. Since it is a powerful one-time item, it should only be equipped when the user is in complete danger. The crucifix does not work on April Fools Exclusive Entities (Jeff The Killer, Banana Peel, Greed, Evil Key, Subspace Tripmine).Using the crucifix against either Seek or the Figure will appear to work at first, though the sigil on the floor will suddenly turn red and the trapped entity will be released as a shattering sound is heard. If the player is using safespots to hide from either Rush or Ambush, holding the crucifix out while being at the safespot can be a great way to ensure survival, as if in case either Rush or Ambush catches the player at the safespot, the crucifix will be used, saving any and all players hiding at that spot, and if the safespot worked, the crucifix will not activate, which can be saved for later. The crucifix is connected with the Guiding Light, as when it's activated, the chains appear to be the same color as Guiding Light, along the cross turning blue before it disappears.
