Spirit Beast

The Spirit Beast is a character encountered during the Spirit of Summer quest. It is the highest leveled character in all of RuneScape, surpassing TzTok-Jad, the previous record holder. While it is not attackable, it will swipe you away if you come near it, doing around 1-8 damage.

Spirit of Summer quest
Players do not attack the Spirit Beast directly, but instead capture it using discs in the quest. Some consider it to be the Wilderness beast, since it is the highest leveled creature in the Wilderness. To weaken it, players must be with the summoned familiar and the Spirit Beast on the disc. If the beast gets too close to the familiar, it ends up devouring the familiar. Players must do this three times to weaken it completely so that it can be trapped. It is never defeated at the end of the quest.

Trapping the beast requires speed and precision, and since it cannot be fought, it is considered more of a challenge than a fight.

History
The Spirit Beast has been terrorising the towns and villages in the Wilderness for hundreds of years. The beast is the one spoken about in the Ruins while wearing the Amulet of Ghostspeak, as voices of the weakened spirits have been occasionally heard in certain areas of the Wilderness.

The Spirit Beast is known to devour spirits of people (or any other creature), making them weak and unable to communicate with the real realm of RuneScape. These spirits, once weakened, are unlike the usual ghosts in RuneScape, where they cannot be understood even with the help of the Amulet of Ghostspeak. Wandering as helpless shadows trapped within the Spirit Realm, they are doomed to suffer in horrible agony for eternity, the beast slowly feeding upon their life force and imprisoning them within its domain.

However, Summer Bonde is able to enlist the help of an adventurer. She, her father Erik Bonde, and his farmhands Jallek Lenkin and Meranek Thanatos, are able to trap the beast using the ancient power of spirits and discs. The adventurer had helped weaken the beast by luring the beast onto the discs using a Spirit familiar. However, the help of the adventurer makes the beast stronger, as it absorbs the adventurer's soul even as they fight to stop it.

This clearly is frowned upon by Summer's father, as he thinks the adventurer was helping the beast rather than the spirits trapped within the Spirit Realm. He asks the adventurer to leave, and it is unknown whether the beast has become stronger. Just when the beast is about to break free, the adventurer is teleported away by Summer from the Spirit Realm.

Trivia
The Spirit Beast appears to be an undead or a "Revenant" version of TzTok-Jad, and is stronger then the normal monster as all Revenants are.
