Hey, happy to give you another update on PotionZ. This is a pretty major update and adds multi potion effect funtionality to the plugin! Yay!
Adds support for multiple potion effects
The buttons in the menus are switched around a bit, but the changes should be easy to understand
You can get multiple potion effects for potion items or apply them directly
Adds support for HasIcon flag (as a toggle) which changes whether the player sees the icon for the potion effect in the upper right corner of the screen when the effect is applied
Adds /give commandblock for custom potion item
Adds indicators for potion particle and icon in the potion descriptions (toggleable via config)
Fixes an issue where the add/remove duration/amplifier would reset the particle settings in the background
