hi every one,

does the response of her affect all Chars in play or only one char chosen?

or does she receives 1 Power from every char in play or just one from a chosen char.

Response: After you lose a challenge, move one power from any charater to Ellaria Sand.

Only from one, of course. Note that she gets one power from "any" character, not from "every" character.

so any always means "any one ", right.

Yes, that's what any means.
