ThunderSheep's Creatures

For now, this mod adds 3 more mobs.

Hunter: A fast, ruthless close-range fighter. Armed with a shotgun, the Hunter thrives up close, shredding enemies before they can react. His dash ability lets him burst forward in an instant—closing gaps.

Ghoul: A malevolent spirit that creeps closer when unseen. Freezes instantly when observed. While watched, it releases three will-o’-wisps that seek the player; contact causes temporary blindness, allowing the Ghoul to resume its attack. Avoid the wisps or keep your vision clear—looking away is deadly.

Stoneling: A living statue with near-impenetrable defenses. Automatically blocks all incoming attacks while on guard. The only opportunity to damage it comes after it strikes—when it lowers its arms to recover. Patience and precise timing are the key to bringing it down.

Ghouls drop Phantasmic Souls, which can smelted down into phantom membrane.

A Hunter can drop a Hunter's Knife, which lets you dash in any direction and gain speed.

1.0.1

Bogling: Hostile amphibious humanoids found in mangrove swamps.

Emberwing: A firey bat found in the Nether.

Their wings can be used to brew fire resistance potions:

Altar of Void:

A new structure, at its center lies a void fountain. By right-clicking and placing a Totem of Undying into the fountain, the altar consumes it and grants an image of the Void.

Voidguard: A powerful guardian summoned from the Void by using an Image of the Void on an Altar of Void.

Mechanics:

Teleportation: The Voidguard can teleport short distances to close in on targets.

Void Smoke: The Voidguard summons clouds of deadly smoke that damage anyone inside.

Staff Strike: The Voidguard can do melee attacks with their dark staff.

Stance Meter: Hitting the Voidguard builds a meter; when full, the Voidguard is stunned for 3 seconds, leaving it vulnerable.

On death, the Voidguard drops its void staff.
