The Catacombs - Floor IV

The Catacombs - Floor IV is the fourth floor of The Catacombs, featuring BOSS Thorn as the boss of this floor.

Overview

Floor IV introduces several new mobs and mechanics.

You can no longer respawn naturally. The only way to respawn is with Revive Stones or if you have a Healer in your party. Fairies no longer respawn.
The Watcher is assisted by two Watchful Eyes. They deal heavy damage to players who try to avoid Undead attacks by camping high places in the Blood Room.
The Super Tank Zombie replaces Tank Zombies, and two new mobs spawn: the Super Archer and Withermancer.
The Frozen Adventurer has a chance to spawn as a mini-boss: their attacks compose of striking lightning to nearby players and using its Ice Spray Wand to stun you and amplify its damage dealt.
The Treasure Talisman and Dungeon Chest Key have a chance to drop from Dungeon Secrets.
The Quiz puzzle is available starting in this floor and all floors succeeding it.
Scarf has a small chance to spawn as a Watcher Undead and drops a Scarf Fragment.

New obtainable items include:

Spirit Sword
Spirit Shortbow
Spirit Boots
Spirit Stone (Spiritual)
Spirit Wing ( Spirit Sceptre, Bone Necklace)
Spirit Bone ( Bonemerang, Bone Reaver, Bone Necklace)
Spirit Mask (exclusive to Master Mode)

Thorn

Upon entering Thorn's arena, they will summon several Spirit Animals, each with unique abilities. Killing 25 Spirit Animals summons a Spirit Bear, which must be killed to drop a Spirit Bow. This Spirit Bow must then be fired at Thorn: 4 successful hits will kill Thorn, requiring 100 animal kills to defeat them.

While in Master Mode, 30 kills are required to summon a Spirit Bear, and Thorn dies in 6 hits instead, meaning 180 animal kills are required to defeat Thorn.

The Spirit Bear spawns near the middle of the arena, and takes a little over 3 seconds to spawn. Mods such as Odin can display the Spirit Bear timer and number of mobs killed to spawn it. Mobs that are killed when the Bear is spawning or alive do not count towards spawning a new one.

Image	Name	HP		Dmg		Behavior
Image	Name	Standard HP	Master Mode HP	Standard Dmg	Master Mode Dmg	Behavior
	Spirit Bull	1.5m	36.75m	3320	84k	Spirit Bulls charge towards the nearest player, dealing 10-15% of the player's Health as True Damage.
	Spirit Wolf	500k	12.25m	5400	840k	Spirit Wolves chase the nearest player quickly and deal significantly higher damage than other Spirit Animals.
	Spirit Bat	300k	1.75m	2800	70k	Spirt Bats swarm the air, but do not attack players unless they are at least 4 blocks above the ground: when they do, they do not respect invincibility frames and can easily kill players near-instantly if they are caught in a large swarm. They can be deterred by a Decoy.
	Spirit Rabbit	675k	7.75m	3720	84k	Spirit Rabbits run towards the nearest player and deal both minimal damage and lots of True Knockback. This can launch players into Spirit Bats.
	Spirit Chicken	350k	4m	1160	336k	Spirit Chickens slowly descend from the sky, striking players for 25% of their Health as True Damage. If they land on the ground, they become a Chicken Mine, and explode upon being walked on for high Damage and True Knockback.
	Spirit Sheep	650k	14.8m	22400	784k	Spirit Sheep will chase the player, before detonating after a few seconds and dealing significant damage and True Knockback upon exploding.

Thorn spawns near the opposite end of the arena of which you spawn in when you enter the boss fight. At around 15 seconds into the boss fight, Thorn will begin traveling slowly, counter clockwise.

Thorn only takes damage from arrows shot by the Spirit Bow. When Thorn gets damaged, he will begin moving in the opposite direction. After thorn has been shot with Spirit Arrows at least 3 times, he will begin changing directions randomly while flying.

Thorn can also be stopped in place with other items such as the Tribal Spear. This will stunlock Thorn for a few seconds when thrown, and can keep Thorn in place infinitely. However, they will not deal any damage.

Dungeon Chest Loot

Depending on the party's Dungeon Score in Floor IV, they will unlock higher tiers of Dungeon Reward Chests.

The Wood Chest, Gold Chest, and Diamond Chest are guaranteed;
A is required to unlock the Emerald Chest;
S is required to unlock the Obsidian Chest.
