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.
