Cruel

Cruel is one of the auras you will never get, and the page for it is mostly a description of how it looks. The wiki labels it developer-exclusive and says it cannot be rolled or earned by players, so there are no odds and no added version on record. It may also have been removed from the game altogether, according to a note about the developer who owned it.

What it looks like: a slightly transparent black glass-cracking effect under the player, similar to the cracking screen at the end of the roll animation for auras between 99,999 and 1,000,000. The player lies in a pose like Bounded : Unbound's but on the floor, wears a black mask with a red smile like Flushed : Lobotomy and the :Flushed: aura, and is surrounded by black squares with warning signs and stop signs embedded in the body. The wiki says it is the second aura with special characters at the start and end of its name, and it uses the Shadows Into Light font.
