Anyone can advantage on stealth checks though, you just need a level 3+ spellcaster with Enhance Ability.
And Enhance Ability: Dexterity aka Cat's Grace also gives you Advantage on Sleight of Hand and Acrobatics, too.
The advantage of Lightfoot Halfling and Grey Gnome is just -- they have it always.
By the way the Halfling ability applies always. You also have far less critical misses in combat, for example. Basically if you can get your attack high enough its far less likely to ever miss.
Of course thats all childs play compared to the Rogue level 10 ability to always roll at least 10 on skill checks.
Either way I'm not unhappy that people think the Halfling special is weak, because that means its likely to stay.
We already have people demanding in other threads that Halforcs need to be nerfed.
Edit: Oh and I'm not looking for even more race ranking.
Well then maybe dont answer this thread ? ;-)
