I feel like you’d have an easier time just making the elixirs last forever until you overwrote them with another type, but add more flavors instead of just creating a brand new system for them to apply to pieces of armor/weapons. It feels like you’re trying to overcomplicate the current system by adding a new system on top of it. Similar to how they went from the Cube in D3 to the Codex system we have now. They overthought the problem.
