Two questions...

[Master Cerberus]

First: The text on Alexa Genecourt does not specify her react to be once per turn, I just want to verify that it can be used an unlimited number of times per turn/per action...

Second: Here is a scenario, I have two characters in the front rank, character A and B. Both have riposte and defend. To make this simple lets assume I am able to pass all my checks. When character A is attacked and character B redirects the strike/action to itself can character A carry out a riposte? Can I do the same thing again by moving it back to character A and then using B to riposte?

Both are Answered in the rule book.

A single react may only be performed once in response to a
single “trigger,” regardless if that react is an action printed
on a character, action or item in play, granted by a trait
or another character, or represented by an action card in
your hand (though multiple copies of the same card may
be performed).

Unlimited during the turn not for a single targeting of an action


A character (or item) that has had a strike or action
successfully redirected to a new target is no longer (and
is considered to never have been) a target of the strike
or action. For this reason, redirection has little effect on
Mass Targeting actions – the action will simply target
the character anew. Similarly, the character performing
a Multi-Targeting action may simply choose to target the
character again.

The character is not nor ever was a target for the strike, hence no reposte.
