So the Pyromancer is a pretty fun starting class. The fireball spell you start with is reasonably strong early, but has pretty limited uses (8). Now here's my topic of discussion: Pyromancy does not seem to improve the same way as Sorceries do (with the attunment stat).
I haven't found it yet, but I'm sure there is someone I can rescue or find who will improve my Pyromancer's flame/catalyst thing, and I hope to god that when I upgrade it it gets some INT scaling or something because currently my spells are stuck at base damage. So while an interesting choice early, I haven't found any new spells or a way to upgrade the ones I have.
Hopefully there are some great spells to gain later on to balance this out, as being stuck at 8 uses of your 1 spell is pretty lame.
