The night beast is a superior variant of the dark beast. It has a chance of spawning after purchasing the unlock Bigger and Badder for 50 Slayer reward points from any Slayer Master. Like their standard variant, they will only use their Magic attack if attacked first (which will always be the case since they are not aggressive) or from afar.

The night beast has a special attack where it will briefly stop attacking then it uses Magic for three attacks which resemble Fire Blast, covering a 3x3 area dealing damage equal to 1/3 of the player's current Hitpoints (rounded down). If the player is below 3 hitpoints the special attack's damage will round down to 0 so it is incapable of killing you^[1] (note that this rounding does not apply to the standard magic attack the night beast will do when first attacked by the player or when the player is out of melee range). The simplest strategy is to use the protection from melee prayer and let the special attacks hit you, making sure you do not leave the monster's melee range.

Using a goading potion to aggro the night beast will still result in it using its standard magic attack as the first attack, and it will still use its magic special attack.

In addition to 100% drops and tertiary drops, superior Slayer monsters will always roll 3 additional items, of which only 1 roll may be from the superior unique table. The other rolls are performed on the regular counterpart's table; their displayed drop chances represent a single roll.

Drop rates are estimated based on 47,056 samples from the Drop Rate Project, unless otherwise cited.

The average Night beast kill is worth 353,130.13.

The average Night beast kill while on a Konar task is worth 438,785.28.

The average Night beast kill in Iorwerth Dungeon is worth 488,310.00 due to the additional chance of receiving a crystal shard as a tertiary drop. This value for crystal shards assumes that they are made into divine super combat potions.

There is a 24/128 chance of rolling the herb drop table. When the drop table is rolled, there is a 4/5 chance of dropping 1 herb and a 1/5 chance of dropping 2 herbs, leading to an average of 1.2 herbs per roll.

There is a 4/128 chance of rolling the rare seed drop table.

There is a 3/128 chance of rolling the rare drop table. There is also a 3/128 chance of directly rolling the gem drop table.

The chance to spawn a superior creature is 1/200.^{[d 1]}

• Night beasts used to have the highest combat level out of the superior Slayer monsters. They have since been surpassed by guardian drakes.
• Dark beasts received a 60% Earth elemental weakness in the 25 June 2025 Summer Sweep Up update, but night beasts lack this elemental weakness.
