What Hollow Knight Randomizer 4 is
Hollow Knight Randomizer 4 is a free Windows mod that changes item placements and transitions in Hollow Knight for patch 1.5 and later. Its item settings can include skills, charms, keys, shards, relics, maps, grubs and boss essence. Players can choose no transition randomization or use Map Area Randomizer, Full Area Randomizer or Room Randomizer. Novelty options include Randomize Swim, Randomize Nail, Split Claw, Split Cloak and Split Superdash. The mod lets players save and load settings profiles and create shareable codes for base randomizer settings; codes are tied to the mod version. RandoSettingsManager can synchronize randomizer settings and most connection mod settings, though using its codes requires an internet connection. The mod creates tracker, helper and spoiler logs in the Randomizer 4 folder in the save directory. It requires Hollow Knight Modding API for patch 1.5 or later, MenuChanger, ItemChanger, RandomizerCore and RandomizerCore.Json. It does not work with patches 1.4.3.2 or earlier. Benchwarp and QoL are strongly recommended and may be needed for certain logic or modes. The repository lists an LGPL-2.1 license.
