And yet if some players choose to randomly roll some of their characters' languages (and if Umber Hulk is on the table to be rolled - is it?) then who knows - maybe someone does speak Umber Hulk.The problem is it can't.
It's the fundamental issue D&D fans struggle with.
At some point, at the last point, you have to choose looks, story, or gameplay.
I just looked up the umber hulk monster.
It speaks umber hulk.
No PC in there right mind will have knowledge of speaking umber hulk before meeting a humblehawk unless they were purposely going to meet in umber hulk.
This sort of thing comes up in my game all the time - they meet some bizarre creature I've never DMed before and maybe someone in the party just happens to be able to speak to it. Or not.
If you include all the dialects my game has about 120 (at a guess, I've never counted them all) different languages in it. And that's just some of what's out there in the setting.
For me, you throw that encouter in there anyway and if someone in the party just happens to speak the right language then maybe the encounter plays out differently than if no such person is present.You will never ever having a standard PC in a regular D&D adventuring party knowing Umber hulk at the point that a random encounter gives them an umber hulk to speak to.
So if your gameplay is based around one of your PCs knowing umber hulk then you've designed a language system that fails it's gameplay because of its aesthetic desires.
In other words, it's not a big deal in the grand scheme of things.
