I think I’m seeing the issue then. In comparison, I have 9 maxed slots currently (5 of which are Lightning Magic - the rest don’t even use magic). I rarely use Acrimonies, and I have only found one Hecate Essence in my playtime (just to experience the difficulty).
Here’s just a snippet of what I’ve ran.
Everytime I want a new slot I level it up, is this time consuming? Yes. Do I have enough time to continue doing this everytime I want a new build currently? Not atall.
Making peace with what’s available is important, and I believe I’ve embraced such a concept wholeheartedly - to the point that the work I put in into an entirely different area ti the majority of people who want to change their build entirely paid off, and now I think I’ll never need a Hecate Essence (or even an Acrimony) for the rest of Arcane Odyssey’s lifespan.
Also out of curiosity, do you not enjoy these files? Crystal is my second favourite magic after lightning and it’s definitely something worth taking a look into if you want to get hooked onto something unique.
