Melisandre's text:
Renown.
Claim 1 additional power when you win dominance, and when you win an unopposed int or pow challenge.
Storm's End's text:
If you win dominance, instead of claiming 1 power for your House, you may claim 1 power each for 2 different Bara characters.
How do these two interact? Do you get 4 power total (Storm's End kicks in twice, once for each power)? Does Melisandre's text make Storm's End irrelevant, because you don't claim just 1 power for winning dominance anymore? It seems like those are the only two possible interpretations.
So what's the deal?
