EverPotion Mod

Everpotion is an amazing mod that gives players the ability to use refillable potions. First you need to use a Slot Unlock item to unlock slots. You can press a hotkey to open the slot overview. The hotkey is set to 'R' by default. Then you can sneak+R to open a GUI which allows you to switch cores. There are three cores and each of these cores have special player effects like Regeneration, Jump Boost and Poison. Once you add these cores, you can close the GUI and open the slot overview again by pressing it's hotkey. Now you can see that the three slots have different icons in them. These icons represent different effects. You will have to wait for the effects in these three slots to charge up. Once the charging reaches 100%, you can use the effect by clicking on the slot. Watch the video below to understand more.
