Some would think there are no major bugs in Wizardry 1 but after playing a while would see that the monsters melee hit chances remain the same for all displayed AC values.
After a more in-depth look it turned out to be a simple mistake. AC is calculated normally but not taken into account for the attack roll. A 1 byte change of code was all that was needed.
Also fixed an annoying typo (”spitits” to “spirits”).
