A little nitpick: Technically the attackers did not even hit Cyanea's regular parry score yet, so her (mundane) dodging alone would have sufficed until now.
Cyanea uses her Counterattack edge on one of the regular brigand's attcks from last round to strike back with -2:
Roll on Fighting: d10 / d6 - 2: 10+8/2 - 2 : 16
In her current round she continues to strike at the non-leader brigands with both of her attacks:
First attack: Roll on Fighting: d10 / d6 : 8/4 : 8
Second attack: Roll on Fighting: d10/ d6 : 7/4 : 7
Damage is again d6+d6 plus bonuses from raises.
