Will you stare into the Darkness? Will you conquer it? This mod adds new challenges, including some new elites. If you run into issues or have constructive suggestions for how to improve the mod, feel free to let me know.


Dark Elites

These elites spawn somewhat rarely, but they bring the darkness with them. When you look in their direction, the darkness closes in. Look away and it will begin to recede, but eventually you'll need to defeat them. Find them in the darkness by following their purple spectral light, but try not to get killed by the many other threats unseen.

Barrier Elites

These elites provide Barrier to their nearby allies while they are alive, so they're a priority target.

Storm Elites

These elites show up relatively late (around the time that Malachites start spawning) and they're just about as tough. They bring storms in their wake that dislocate friend and foe alike.


Not all chests are what they appear to be. Occasionally a chest will reveal itself to be a monster in disguise; beware, for it wields the item that was within the chest and will not yield it until it is dead. As of 1.3.0, a new type of mimic has arrived which likes to pose as small chests; this is still in early beta, so reports of issues or constructive suggestions for balance are welcome.

Technical Notes


Place JarlykMods.Hailstorm.dll in your BepInEx\plugins folder. If you're using a Mod Manager, it may place it under its own folder under plugins, which is also fine. Please note that this mod has several dependencies (as visible in the Thunderstore) that will need to be present in order for it to function.


After you run the mod once, a configuration file will be created under BepInEx\config. It is a simple text file with configuration options that are commented as to what they do. Here you can disable particular features and configure the spawn rate for mimics.
