Incessant chatter (Zeta): at the start of each battle, C3PO inflicts daze (impossible to avoid) to all enemies for 2 turns and grants speed up for 2 turns to R2-D2.
You broke the balls (Zeta): after the first C3PO turn, Han Solo (if present) gets Enraged.
Enraged: Han Solo has one extra turn in which inflicts 200% damage.
At the same time, C3PO is stunned for one turn.
