There is a serious discrepancy in the crafting costs for Bombs and Flasks.
This is entirely disproportionate to the currency value, and inherent usefulness of a 1 use consumable item.
Unless I’m missing something, I think the crafting requirements for these items needs a serious look over. (Not that I expect many look to craft these items anyway, but as it is, why would anyone ever do that?)
You’re not missing anything, it’s just like you said.
I made a whole topic to explain the problem and the possible solutions: The Crafting Materials are an Unintuitive Mess
Great post man! I agree with a lot of what you wrote. I hadn’t come to realise some of it yet, as I haven’t properly explored a lot of the crafting system yet.
This one definitely stood out to me as a “what the hell?” kind of moment. My friends laughed sarcastically about how we must be swimming in gems to be willing to just throw them at enemies.
