A cute mob that you can find in rivers, lakes, and the new wetland biome. This mob can swim and walk on land. However, if it's hit, it will take off flying and may despawn from your world. To prevent this, use shears on it to stop it
from flying. When defeated, it drops meat that you can cook, and over time, it also drops duck eggs that you can throw to potentially hatch.

The Flagon Mysthic is a tameable mob that you can obtain through trades with the Stinky Medical. Once acquired, you need to give it a soul gem to bring it to life and make it your pet. This mob will follow you and can evolve using one of the forges dropped by the Unbound Elemental and the Sentinel. After evolving, the Mystic Jar will be able to trade the best armor in the addon.

To activate its trading abilities, you must interact with it using a material that represents its essence. Once this is done, make sure your hand is empty to open the trading menu. Keep in mind that after activating this state, the mob will no longer be able to sit or follow you—it will only trade with you. If you want it to return to its normal state, simply interact with the corresponding material again, and the Mystic Jar will resume its usual behavior.

The Mercenary is a mob that spawns in ruins generated around the world and can also appear in Outcast caravans. This mob will become aggressive if you open a chest near it. There are two variants of the Mercenary: one equipped with a sword and shield, and another with a hammer. Both types will use a bow if their target is at a distance, and when their health is low, they will buff themselves, becoming a true threat in combat for a few seconds.

The Mercenary will trade items with you when sitting, and you can tame it by purchasing a contract. However, keep in mind that once hired, it will no longer trade items with you.

The Outcast is a peaceful mob, although it has a neutral variant. This mob travels in caravans with other mobs at night, representing a faction or its marginalized status, and can also appear in certain structures. It behaves similarly to a villager but with some additional features. One of the most interesting versions is the one with a chest, which contains very useful items for the start of your survival adventure. However, the choice of whether to respect its peaceful nature or take the resources by force is up to you and your sense of honor.

The Stinky Medical is a neutral mob that appears with a certain probability in houses generated in forests. This mob trades important items such as the jar. Additionally, it will sell you its mask, an herb, its wand, and a syringe with suspicious blood.

If the Stinky Medical is hit, it will summon a Putrefacto to help defend itself. If the Putrefacto is defeated, the Stinky Medical will curse you with the bad omen effect and then resume trading with you.

The Assassin is a hostile mob found in abandoned carts scattered throughout the world. It becomes invisible when targeting an enemy, pursuing and attacking it until it is eliminated. Upon defeat, the Assassin drops its dagger as loot.

The Abomination Duck is a mob that currently only appears through transformation. If you interact with a duck using the syringe with suspicious blood sold by the Stinky Medical, the duck will turn into a mutant. It can also become a mutant through the Plague's roar. In a future update, the Abomination Duck will naturally spawn in a new biome. Its main weakness is fire, and it is particularly vulnerable to sacred weapons.

The Elemental Knight is the strongest normal mob in the addon. It is a powerful tank-like skeleton that deals heavy damage with each hit. Its weakness is its slowness, but it compensates with fire discs that it shoots. In its second phase, the Elemental Knight gains two new attacks:

1.  Explosive Shield: It shields itself, and if it is hit while shielding, it releases an explosion. To avoid this explosion, do not attack it while it is in its shielded state.
2. Aerial Charge: It launches itself towards its target, spinning in the air, resulting in a very powerful attack.

It appears as a guardian in catacombs and in certain structures in the wetland biome. Upon defeat, it drops very important materials.

The Outcast Corrupted is a highly irritating hostile mob. It often appears in the world trapped in a cart wheel, making it very fast and difficult to hit. It can also appear through transformation if an Outcast dies from regular, non-sacred weapons, or with a certain probability when an Outcast becomes corrupted over time, as well as transforming from the Plague's roar.

The Outcast Corrupted has multiple phases, making it a challenging enemy. Its main weakness is fire, and it is particularly vulnerable to sacred weapons.

The Sentinel Soldier is a strong hostile mob that appears in abandoned cart structures around the world. This mob can spawn at night riding a horse, and with a rare chance, it may appear riding a floating boat.

The Sentinel Soldier has multiple combat styles. In its normal mode, it fights with a sword and shield, which can be disabled with a diamond or netherite axe. It can also fight by wielding its sword with both hands, dealing more damage. Additionally, if its target is far away, it uses a bow to shoot sacred arrows that cause fire damage.

Upon defeat, it has a chance to drop its armor and sword. When sleeping, it might become corrupted and start attacking its allies, and it can also be corrupted by the Plague's roar.

The Gargoyle is the only miniboss in this version. This mob appears in a church, protecting the weak from any threats. When it identifies a target, it starts flying and unleashes cutting air blasts, while also dodging your arrows. The best time to shoot your arrows is when it's charging its fireball. If you hit it while it's charging, it will fall to the ground, giving you a chance to attack until it rises again.

In its second phase, the Gargoyle loses its wings and begins attacking in close combat. It also protects itself with a shield that cannot be disabled and counterattacks every time you strike it. Upon defeat, it drops a halberd that deals significant damage and is particularly effective against shielded mobs.

When you interact with the Stinky Medical while holding the syringe with suspicious blood, it will transform into the Plague, a very powerful boss. This boss will bring nightfall each time it screams, corrupt some mobs, and summon two Plague Dogs to aid in its hunt. If you try to distance yourself, it will throw its sword, which transforms into a scythe, and teleport to where it lands.

The Plague has a devastating attack where it inflates its muscles and destroys everything in the area, making it extremely lethal. Upon death, it drops a sack that, when interacted with, will grant you its items. This was designed to prevent the loss of items due to explosions; nothing can affect the sack except for player interaction.

The Sentinel is a powerful boss in the addon, as strong as the Unbound Elemental, and it has a wide range of attacks. It appears in the highest tower of the cathedral, which generates on a floating island in the sky above the ocean. The Sentinel can summon portals that launch sacred weapons and cause giant sacred spears to fall on its target. If the player moves away, it will execute an attack by positioning itself on one of these spears.

When its health is low, it begins to regenerate. If you're too slow, it will fully recover, making it very challenging to defeat. Upon defeat, it drops a sack containing crucial items, such as the Solar Forge.

The Unbound Elemental is one of the most powerful bosses in the addon, with a chance to spawn in a castle in the Nether. It initially appears dormant, but upon awakening, it unleashes its full power. It has many attacks, including a soul fire flamethrower, summoning Unbounds to assist in battle, and launching a massive soul fireball, which it also shoots if the player is far away.

In its second phase, its helmet shatters, releasing two spectral skulls that aid it in combat by launching soul fire orbs. Upon defeat, it drops a sack that, when interacted with, provides very valuable items, including its Forge of Darkness.
