What it is

Hollow Knight Randomizer 4 is a free Windows mod that changes item placements and transitions for Hollow Knight patch 1.5 and later. Item pools can include skills, charms, keys, shards, relics, maps, grubs, and boss essence. Transition settings range from no randomization to Map Area Randomizer, Full Area Randomizer, and Room Randomizer. Additional options include Randomize Swim, Randomize Nail, Split Claw, Split Cloak, and Split Superdash. Players can save and load settings profiles, and generate shareable codes for base randomizer settings; codes correspond to a specific mod version. RandoSettingsManager can synchronize randomizer settings and most connection mod settings, with an internet connection required for its codes. The mod writes tracker, helper, and spoiler logs to 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 support Hollow Knight patches 1.4.3.2 or earlier. Benchwarp and QoL are strongly recommended and may be necessary for some logic or modes. The repository identifies the license as LGPL-2.1.
