Hallownest's Remains

The mod draws on the remnants of ancient civilizations from the Hollow Knight series, including Hallownest and Pharloom. Players gather soul, charge a spell system with two spells, and cast them once the required charge is met. Soul is gained through several means, such as consuming a soul bottle, and vigor charge heals up to three hearts through the Z key.

Progress runs through a forging mechanic. Players craft an old nail or needle, upgrade it into a stronger nail, then combine it with a weapon upgrade slurry specific to each weapon metal. The mod adds two new weapon types, three new ores, a custom stone variant and an enchantment infusing mechanic. Pale ore is found in a structure called the pale egg, deep in an underground dig site. Two custom biomes and a few custom structures are added, along with a new villager type.
