How to Avoid Summoning SCP-2521

Watch What You Type in Chat

SCP-2521 spawns instantly whenever "2521" appears in any chat message. This includes:

• Casual conversation
• Coordinate references (e.g., "meet at X: 2521")
• Random numbers or jokes
• Even partial contexts where the number appears

Before sending any message, scan it carefully for the forbidden number. If you need to discuss the mod, consider using alternative phrasing like "the entity" or "that creature."

Check Signed Book Titles

SCP-2521 also triggers when "2521" is written as the title of a signed book. Never title books with this number, even as a joke or reference. The entity will spawn the moment you finalize the book's title.

Prevention Strategy

The safest approach is to establish a server rule or personal habit: never type or write the number in any context. If you're playing multiplayer, warn other players about this mechanic so they don't accidentally summon it during casual conversation. Consider using a chat filter or simply being vigilant before hitting send.
