PotionExtension
Minecraft Java mod. Downloads from the MC Java Mods app on Android.
⬇ Download on CurseForgeThis mod extends a potion array size to 128.
And this mod supports array extending over 128 to 256.
I know it is possible to extend a potion array using reflection.
Some mods use reflection to extend a array.
It works fine when array size is less than 128 but doesn't work over 128.
This problem is caused by potion id managing(saving id as signed byte).
Use PotionExtension and enjoy mods adding excellent potions.
<Configuration>
checkPotion : check conflicting of Potion ID
maxPotionArray : set maximal index of potion array.

Unfortunately (for me), this mod is needless to contain your mod environment in 1.8.9 or higher.
Because why I release mod working on 1.9 or higher ver Minecraft.
