I knew I recognized your style from Quintessence! I bought it some time ago.
Anyways, these are great, adding a lot of variety to spells and with plenty of great homages to games like Final Fantasy.
When I see the Halloween animations, I can't help but think of Bravely Default and Ba'al Turtle Dove for a moment, even though it didn't use any such attacks. Though things like Heartbreaker would be right up its alley.
Turning a specific vibe into reality is incredibly difficult. For instance, this song is one of the ones I listen to when working on my post apocalyptic project, and getting it's "feeling" into the game has been a real challenge.
I don't just wanna regurgitate the numbers I see, I wanna actually understand the calculations I'm making so I'm probably gonna make a post later with some calculations and what I THINK they mean to get some advice and corrections.
Edit: All (Most) of these will be tested in game prior. I just wanna make sure I understand what's going on under the hood if you will.
