If you die with any active buffs, they will be canceled out and need to be re-applied on respawn.
You can have up to 22 buffs active at once. After that, when you try to activate another buff, it cancels out the left-most buff in the bar. Activated buffs carry over from server-to-server, and from world-to-world.
Buffs can be easily activated with the buff hotkey, defaulted to B. When pressed, the first 10 buff-granting consumables (starting from the top-left) are used, giving the player their respective buffs. Using the hotkey while a particular buff is still active will not re-activate it or re-stack it.
