The Corporeal Beast, often referred to simply as Corp, is a large monster residing in its lair, accessible via a games necklace or through an entrance in level 21 Wilderness east of the Graveyard of Shadows. It has a very large health pool of 2,000 Hitpoints, coupled with high Defence and 50% damage reduction against most weapons; only Corpbane weapons (on stab attack style) and magic deal full damage. Additionally, the special effect of ruby bolts (e) deals the full 100/110 damage. If all players leave the room, its Hitpoints regenerate at a rapid rate.

The Corporeal Beast is the only monster to drop the spirit shield, as well as the holy elixir and arcane, elysian, and spectral sigils, used to enhance it. In addition to its sigil drops, the Corporeal Beast has many other valuable drops.

Players can pay 200,000 coins to open a group instance for their clan.

Fight overview

Main article: Corporeal Beast/Strategies

The Corporeal Beast's Lair is located in level 21 Wilderness, although players can teleport directly there using a games necklace. This will take the player to a small safe room with a large doorway to Corporeal Beast.

Ironmen with a combat level of 90 or higher have a separated Corporeal Beast room. All other accounts use the normal room. This is to reduce griefing and ironmen using normal accounts to use stat-reducing special attacks.

A group of players fighting the Corporeal Beast.

The Corporeal Beast has a 50% damage reduction against any weapon that is not a Corpbane weapon on stab attack style. Although magic attacks also deal full damage, they are generally very inaccurate against the boss. Protect from Magic does not fully block its magic attacks; it only reduces the damage by 33.33%. The Corporeal Beast has very high accuracy, damage, and Defence.

While fighting the Corporeal Beast, there is a chance that the dark energy core will spawn. This creature leeches Hitpoints from any players adjacent to it to heal the Corporeal Beast, and jumps to players if none are adjacent.

Historical

The Corporeal Beast was originally released on 15 September 2008 in RuneScape. However, there are several differences between the iteration of this boss in Old School RuneScape and the original in RuneScape.

• It could only be fought after completing the quest Summer's End. As the quests involving it are not present, no lore exists for the Corporeal Beast in Old School.
• The Corporeal Beast's lair was much larger, although it only resided in the last room. The entrance to the lair was also 14 Wilderness levels deeper than the one in-game.
• The original Corporeal Beast could drop a divine sigil, which could be used to create a divine spirit shield. Its effect was a constant 30% damage reduction per attack received, with 50% of that blocked damage instead drained from prayer points.
  • The divine sigil's addition to Old School RuneScape has been polled twice, on 18 September 2014 and 15 February 2019, failing to reach the 75% threshold of passing at 66.1% and 72.8% respectively.
• The original Corporeal Beast could drop the regen bracelet.
• The original Corporeal Beast was fought slightly differently by players. It boasted a higher maximum hit with melee of 51 instead of 33, as well as being vulnerable to poison. However, it would very quickly remove its poison unlike other monsters vulnerable to poison.

Trivia

• Though not explained in Old School RuneScape, the boss's name originates from the Summer's End quest in RuneScape: as the Spirit Beast was defeated in the Spirit Realm, a mirrored version of Gielinor where everything is opposite to the physical world and vice versa, the Corporeal Beast was incarnated in the physical world to replace the Spirit Beast in the spiritual world.
• Also explained in RuneScape is that the markings on the ground are the graves of the residents of Bonde Farm.
• The magic area-of-effect attack the Corporeal Beast uses was originally named [corp_sperm_splash] in the game's code, though it was renamed to [corp_magic_splash] on 28 October 2020.
• Pets cannot be brought into the Corporeal Beast's lair. Attempting to enter the cave while having one following the player will cause a message to appear in the chatbox, stating Your follower hides in fear and refuses to enter the cave. If the player attempts to drop their pet while inside, the chatbox will instead state Your follower hides in fear and won't come out. This is also a nod to RuneScape, where the Corporeal Beast is capable of eating Summoning familiars, which are also followers.
• Corporeal Beast had a festive override wearing a santa hat during the 2023 Christmas event.
