... all of these are BG1 leftovers; I believe they're not supposed to be as powerful as, say, the Equalizer. In other words, you're not supposed to be able to hit late-game monsters with them.
Sorry, but what would those be ?
In my opinion, a creature that was made to be hit with a +2 weapon should be hittable with any +2 weapon, even if it was made to be a +2 against just goblins, cause it has a special hunger for goblins blood.
Now unfortunately the game doesn't have damage threshold for this like things, so smashing with god strength with a +1 weapon doesn't do a thing against Iron Golems. While it would in a more well defined system.
Now then, what comes to the +x vs creature type items, no one says it has to be a Stonemasher +2/+4. It could be Stonemasher +2, and note that you would have the extra +2 to
thac0 and damage in the item effects, which has no bearing about the enhancement it has. So there won't be arguments about what it can hit, or can't.
Also usually a +2 vs a enemy type is too small bonus in my opinion ... as there's only so much usage you get out of it. A +4 to damage would be something better(with +2 to
Thac0). This is likely the reason why the "War Hammer +1, +4 against Golems" is likely to have the +4, instead of +2. The bonus of 1 is likely to have been too small of advantage, and it was designed when the Enhancement level was not TEH requirement to hit things with.
There's a very good example here, the Kondar to argue about, now it has no flaws in the original game, except that people might think it as a +1 sword instead of +3. Either for me is fine actually, but what a mod maker needs to make a special account is that the weapon is a +3 vs Shapeshifters, which include the Werewolves, and in so the game content with the Loup Garou creatures. Now the sword has had been falsely flagged by several good mods as not non-steal weapon(or golden in one of the moding tools), which made it unable to hit the one of the most dangerous Shapeshifter creatures in
BG1 game (in
BGT). Since then, they have redacted that action in each of the mods, but you should still consider it a feature, and as such a warning like the sword of Damocles, you have to know what exactly you are implementing. You can't just blindly go ahead.
