DatapacksJava
Toxin Accumulation│毒素堆積
I don't know my version or loader
Open the Minecraft launcher and look at the profile you play on — it names both, like fabric-loader-1.21.4. The version also shows in the bottom-right corner of the game's main menu.
No loader in the profile name? Then it's plain Minecraft, and these mods won't run — you need Fabric or NeoForge installed first.
Function│功能
If a Bogged's arrows hit a mob already affected by Poison, they will be inflicted with a level of Poison one higher than the mob's original level, lasting 4 seconds.│沼骸發射的箭矢擊中生物時，如果生物已經帶有中毒效果，會獲得比原本的中毒效果等級高1級的中毒效果，持續4秒。
Precautions│注意事項
The datapack achieves this effect via a custom enchantment called "toxin_accumulation", so if you see an enchanted book with the "toxin_accumulation" enchantment in your Creative Inventory, please ignore it.│該資料包透過名為"toxin_accumulation"的自訂附魔來實現此效果，因此如果您在創造模式物品欄中看到帶有"toxin_accumulation"附魔的附魔書，請忽略它。
