Locate Wither Roses
Wither Roses are the core ingredient for every Potion of Decay, so knowing where to get them matters. In vanilla they appear where the Wither kills mobs, and Rewithered keeps them relevant to decay brewing. The most reliable method is to summon a Wither near a group of mobs and let it kill them, leaving Wither Roses behind. You can also find them naturally in the Nether, particularly around wither-related structures and fortresses.
Find Wither Skeletons
Rewithered tweaks wither skeleton spawning so they appear in more biome- and structure-based locations rather than only in Nether Fortresses. Explore Nether biomes and structures that the mod has flagged for spawn replacement — you will encounter wither skeletons in places vanilla would not put them. This makes farming them easier if you set up a mob farm in the right area.
Farm Their Drops
Wither skeletons in Rewithered use bows and fire Arrows of Decay at you, so bring a shield or ranged weapon of your own. Their adjusted drop tables mean you should check what they drop after killing them, as the mod changes the loot to better integrate decay mechanics. Collect Wither Roses and any decay-related drops to fuel your brewing and arrow crafting.
