Just curious as to whether multiple instances of renown stack on a character or if that character only ever claims one power regardless of how many times it has it?

Thanks for your time.

Keywords only count one time when they are used. The only reason to ever stack keywords are to counter effects that take them away.

Thanks for the clarification.

Specifically, the rules say that when you win a challenge, each of your characters with Renown claims 1 power. So the check when renown is awarded is simply "yes or no." Having renown more than once doesn't result in anything more than "yes," so it doesn't result in anything more than 1 power.

Same thing for stealth. Since you are allowed to bypass one defender for each of your attacking characters with stealth, the check for stealth is also "yes or no." Extra incidences of stealth don't make the "yes" more emphatic or anything.
