PotionPacker
PotionPacker is a lightweight utility plugin that allows potions to stack
using the Paper Data Component API (MAX_STACK_SIZE) — without NMS or reflection.
Features
- Stack normal, splash, and lingering potions
- Per-type stack size configuration
- Optional profile-based system with permissions and priorities
- Live config reload support
Profile system
PotionPacker supports an optional profile-based mode:
- Profiles are enabled via a config toggle
- Each profile is bound to a permission:
potionpacker.profile.<profile_name> - If a player has multiple profile permissions, the profile with the highest priority is used
- Profiles inherit missing values from the
defaultprofile
