As much as I miss THAC0 (seriously, THAC0 was a great system), this feels really backward.
I do like that they explain it in a tooltip, though. I'll probably get used to it.
Totally agree THACO made way more sense.
The way it's currently implemented basically
is THACO, right?
THACO takes into account all your modifiers and tells you what number on the d20 hits each AC.
BG3 dialogues take into account all your modifiers and tell you what number on the d20 passes this DC.
