Hi,
I read that there used to be a PnP THAC0 table that let the base THAC0 go into negative values, but that there were problems with it [here] ; however, with the current tweak, THAC0 only decreases up to 1, whereas in the unmodded 2DA table provided with BG2:EE, it does go down to 0. This means that the tweak is actually a slight nerf for fighters and monks after level 20 ! Anyway, the tweak description, “THAC0 can now progress until it reaches zero instead of no longer improving once you hit level 20”, is wrong. (“once you hit level 20” is also inaccurate because in the original THAC0.2DA file, fighters get their THAC0 of 0 at level 21, and mages and shamans still get a decrease when they reach level 22.)
In the linked post above, Miloch had written he believed that a THAC0 value of 0 was still valid for the engine even though IESDP says 1-25, and I also think that’s true. Some creatures, like fire giants, have a base THAC0 of 0, too
So, shouldn’t this be changed ?
