Rewithered Mod Guide: Decay Potions, Arrows, and Wither Skeleton Changes

Brewing and Using Decay

Rewithered Mod centers on the Wither effect. You brew a Potion of Decay by combining an awkward potion with a wither rose in a brewing stand. From that base potion you can create long and strong variants, which trade duration against potency, and you can further brew splash and lingering forms just like other potions. Lingering Potions of Decay can be used to craft Arrows of Decay, following the same process as other tipped arrows. Fired from a bow, these arrows apply the Wither status effect to whatever they hit, giving ranged combat a decay option that pairs naturally with the potions.

Wither Skeleton Tweaks

Beyond brewing, the mod adjusts wither skeletons so decay feels integrated into the world. Their spawning changes based on biome and structure, with some spawns replaced to fit the theme. Wither skeletons can also use bows, letting them fire decay arrows at you, and their drops are adjusted to match these new behaviors. Expect them to feel more like a coherent decay-themed threat rather than a plain melee mob.
