immune to charactor abilities

By mnBroncos, in 2. AGoT Rules Discussion

real nube question here just doesnt explain great in the rules but these do not include traits right like stealth?

Well Stealth is a keyword, and a keyword is not a character ability. You should read the FAQ which is found under the support tab for the AGOT news page.

ie, "correct; immunity to character abilities does not protect from keywords like stealth, deadly, intimidate, and so forth because keywords are, by definition, not character abilities."
