Hello. I'm commenting to inform you that I found a bug with the plugin when using the latest version of your DualWield plugin.
I keep getting an error in the console command that "Ramza.DW.damageCalc" is not a function. It also displays:
at Window_BattleLog.callNextMethod (rmmz_windows.js:5422:31) 'a.atk * 4 - b.def * 2' 'DAMAGE FORMULA ERROR'
When the DualWield plugin is turn OFF, the WeaponAttackFormulas plugin works perfectly.
