yes this is not pure 5e dnd this is a video game call baldur's gate 3, this information I gave you come from the official wiki and can be tested in game.
I did just test it.
Hag who has been hexed to have disadvantage on Dex Ability Checks: 50% chance to hit with Sacred Flame. Rolled 1d20 in the combat log.
Hag who has not been hexed: Also 50% chance to hit with Sacred Flame. Rolled 1d20 in the combat log.
Conclusion: Hex doesn't affect STs
Of course, this might be a bug specific to hags, or Larian might
want disadvantage to affect all 3 of STs, ability checks, and attack rolls but have not implemented it yet.
You are correct - Ability checks and Saving throws are totally different things, and Hex is designed to target only ability checks. Nothing in the game indicates that the spell has been changed to target saving throws (the only thing that's changed is the duration)
Here's Jeremey Crawford's
ruling on it.It'd be way too overpowered as a level 1 spell if it can affect saving throws. Imposing saving throw disadvantage is super rare in 5e as it's one of the most devastating debuffs. There's a reason why people think the College of Eloquence Bard subclass is extremely OP is because they can do precisely that.
Edited:
I say hex is bugged
but I guess then if you use grease. then she will have a hard time to stand up and then your sacred flame will hit
ah no,
its a saving throw too , so tell me, ? what is the point of this debuff on Ability check ? in a combat on a mob in a video game.
The important thing to remember is that in 5e, Skill checks = Ability checks (but with applicable proficiency). So in BG3 combat, that means:
Hexing Strength will give disadvantage on attempts to shove/grapple, and also to resist them. No grapple in BG3 yet, but we all know how powerful shove currently is.
Hexing Dexterity will give disadvantage on enemy stealth attempts. We haven't faced rogues yet, but this may come in handy in specific scenarios.
Hexing Intelligence in PnP will give disadvantage to enemies on disbelieving your illusions - i.e. via the Phantasmal Force spell. Not 100% sure how that is translated in BG3 yet.
Hexing Wisdom will give disadvantage on Perception, which translates to easier hiding for you - which in PnP helps a lot with sneak attacks (since getting advantage is harder).
Hexing Charisma in BG3 probably does the least, since we can't persuade/intimidate mid-combat. If it is implemented, it will hurt a CHA-caster's ability to dispel and counterspell higher level spells.
Nothing for CON that I can think of skill-wise.
