Darth Bane question:

Because Darth Bane has "Master of the Force", can he use Light Saber assault twice (the same turn)?

Muun Tactics question:

Tactics Broker - is this optional? Card does not state optional? So, can you choose Not to sac your own character?

Thanks again guys!!

A: No, Lightsaber assualt replaces attacks. Once replaced, it's replaced.

ALAS, it is manditory that you must sac Another of your own characters. Unless i've missed a ruleing, the sac char can not be the MTB. Which is why it's considered wise to have a way to off him if need be.

Fox is correct on Both accounts.
