More informative combat log

[DalreiDal]

Is there a mod that makes the combat log more informative, specifically about to hit rolls and saving throws? For example, Minsc and Imoen can both roll a modified 16 to hit, Minsc is a hit, Imoen is a miss. I assume that's because of their different THACO, and the AC of their target. Same kind of logic applies to saving throws. Is there a mod somewhere making that information visible?

In the same vein, is there a mod somewhere that would make the creature information visible, such as resistances, saving throws, etc.? It would be cool if a higher lore score led to more information, or if information about a specific resistance was unknown until you hit them with the specific damage type.

Speaking of... is it theoretically possible to make additions to the UI with mods? I know tooling exists to add NPCs, items, spells, and so on, but not sure about the UI part. For example, opening a window on right click on a monster? Or change the tooltip on mouseover maybe?

IIRC, InfinityUI has a toggle that will give the extra THAC0 information you're looking for. I believe the Reveal Hidden Gameplay Options mod also has an option that can be toggled to give that information. I don't know if either will give the same information for Saving Throws though.

As for creatures, InfinityUI has a bestiary feature that as you kill more of a type of creature, you get more information about it. There is also an external application called BG2 Radar Overlay. You run it while the game is running and it will provide you information about any creatures currently on-screen; THAC0, HP, AC, Saving Throws, Resistances etc etc.
