Hi guys, first time posting here.
I'm working on a game in RMVX with some friends, and am trying to tweak the battle system to better suit our purposes. So here's the gist of the setup I'm aiming for; all combatant types are split into either "physical" or "spirit" types, impacting their attack and defense stats between physical or magical attacks. So a physical monster might have high attack and defense but be susceptible to magic.

We currently are using the Tankentai side view battle system, as well as the Yanfly battle stats, which has dealt with a lot of the problems of this setup, allowing for balanced handling of defenses and special attacks.

The area that I can't figure out is dealing with basic attack damage, which are automatically calculated using the attack stat. This is fine for the physical types, but is problematic for spirit types, since the balancing I'm aiming for relies on the equality of these two types, both in skill set and regular attacks. Do you guys know of any solution that could resolve this issue?
