Elixir (and Enhancer) effect stacking

[asommers]

I still need an answer for my question pls?

You cannot purchase elixirs of the same type. If you have a combo elixir, you cannot purchase any other elixir. If you only have a damage elixir, you can purchase an armor elixir. The stacking was implemented to complement elixirs working with both player skills and NPC buffs/debuffs that also do things like XP, speed, damage, luck and armor modifications.
