Qi Flow: -1.
When you make a Shield Slam you can imbue it with a surge of qi. If you successfully damage your target, they are Stunned for one turn. If the target attempts to resist this stun, the DT is equal to your total Check result for your attack + your current Qi Flow.
The duration of the stun increases by one turn for every 3 Ranks of this Action (two turns at Rank 3, three turns at Rank 6, and so forth).
