Thorn

"Welcome Adventurers! I am Thorn, the Spirit! And host of the Vegan Trials! My Arena is the most entertaining place in all the Catacombs! Today you'll be our spectacle. Dance! Dance with my Spirit animals! And may you perish in a delightful way!"

- Thorn (Welcome Speech)

Thorn is the of The Catacombs - Floor IV. Thorn's remains reappear on Floor V, from which Livid drains energy in order to clone himself.

Lore
Powerful Necromancer who specializes in animals. Calls himself a vegetarian, go figure.

Boss Fight
Unlike all the other bosses in The Catacombs, Thorn only has one phase. However, it is quite a long fight. Thorn will summon Spirit Animals which can deal damage to the player along with a new called the Spirit Bear. A counter (indicated by a ring of Sea Lanterns and Coal Blocks near the audience) shows how many Spirit Animals have been killed. When the ring fully lights up with Sea Lanterns, the Spirit Bear will spawn.

Spirit Bear
The Spirit Bear is a summoned during the fight. It will be summoned once 100 Spirit Animals have been killed. It has (or  in Master Mode) and can attack players with a Golden Sword or a Spirit Bow. The spirit bear will heal overtime, but very slowly.

When the Spirit Bear is killed, an item called the Spirit Bow will appear, and the person who picks it up has only one shot at damaging Thorn. Four successful hits with the Spirit Bow will kill Thorn.

There is a crowd of enemies cheering for Thorn in the arena. While they can't attack the player, they can give helpful hints for Thorn's attacks.

Thorn technically has different phases, but the differences are minuscule. Thorn will speed up the more he has been damaged and when he is about to die in one more hit, Thorn will start turning around, making it harder to hit him. Additionally, the mobs gain more HP.

Occasionally, one of the circles in the arena will change color, either green or orange. If it turns green, it will ready up a Healing Circle much like the Healer's one, but if it turns orange, it will start a fire on that circle. Thorn's spirit animals will take 5% of their HP every second they are in the fire.

In Master Mode, 3 Spirit Bears will spawn instead of one.

Collection
Killing Thorn increases the Thorn collection.

Note: The Thorn Heads gain double stats on floor 4.

Strategies

 * The audience has Fairies hidden among them. Kill them to revive.
 * Sometimes, one of the four circles on the floor will be engulfed in flames. Lure mobs in there with a Jingle Bell as it deals tons of damage per second. On the other hand, sometimes the circle becomes a small Healing Circle (similar to the Healer's ability).
 * Trap mines are very useful for AOE damage.
 * Climb up to the Audience Floor and place a Decoy there. This will lure the Spirit Bats towards the decoy, not only stopping them from attacking players but also being easy kills to summon the Spirit Bear quickly. After that, bait the Spirit Bear over to the stands so you can use ranged attacks on it until it dies.
 * Inflatable Jerry can be used to gain a little air mobility as it will scare the bats, allowing you to go in the air to dodge things. (Verify)
 * Using the Bonemerang to stun Thorn so he is unable to move will make Spirit Bow shots easier to hit. This is mandatory if the player wants to never miss shots on Thorn. Beware of the bats and the chickens; if the player stops stunning Thorn, he will move much faster and it will be very difficult to hit. Note that the Bonemerang costs upwards of and is not worth the money unless the player is an Archer.
 * Each time Thorn takes damage, he will be briefly stunned. If the first spirit bow was saved, an immediate follow-up shot from a second spirit bow will hit Thorn, provided that Thorn has not finished his dialogue.
 * Use the Spirit Boots to fly into point-blank range with the spirit bow to reduce the chance of missing a shot. Alternatively, teleport into the audience area and take the shot from there, as this allows the player to be at around the same height as Thorn.
 * Ferocity no longer works on Thorn
 * Thorn turns around depending on how many players are in its trajectory.

Trivia

 * The Spirit Bow in the Thorn fight has some extra lore attached to it.
 * The Spirit Bow specifically does approximately 75k damage per hit against Thorn.
 * In Master Floor 4, three Spirit Bears will spawn, and all three must be killed to get the Spirit Bow.
