Hollow Knight Randomizer 4
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. Players can choose pools covering skills, charms, keys, shards, relics, maps, grubs, and boss essence. Transition options range from leaving transitions unchanged to Map Area Randomizer, Full Area Randomizer, or Room Randomizer. Additional settings include Randomize Swim, Randomize Nail, Split Claw, Split Cloak, and Split Superdash. Settings profiles can be saved and loaded, and players can create shareable codes for base randomizer settings; codes are tied to the mod version. RandoSettingsManager can sync randomizer settings and most connection-mod settings, but using its codes requires an internet connection. The mod also creates tracker, helper, and spoiler logs in its folder within 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 needed for some logic or modes. The repository identifies its license as LGPL-2.1.

Randomizer 4 may suit Hollow Knight players on patch 1.5 or later who want extensive control over item and transition randomization. It also supports shareable base-setting codes, with an internet connection required for RandoSettingsManager codes.
