Brand new ToEE player here. Love the game so far and really like the Co8 mod. Good job with that. Still on my first playthrough and I'm noticing that Spugnoir and Meleny do not suffer negative repercussions from using weapons that they are not proficient with. They both have only the Simple Weapon Proficiency feats. For example, I can equip Greataxes and Longbows to both Spugnoir and Meleny and their attack rolls never drop. These weapons still include a red border while in their inventory indicating no proficiency. I'm not sure if it's the same with armor that they are not proficient with. I'm not sure what wearing armors without its respective proficiency even does.
