The trigger for PTL is having performed the Daredevil Action.
The sequence is:
- Daredevil (action):
- Perform the maneuver
- As you have performed an action this round, PtL triggers (nests into daredevil)
- Perform Action from your action bar
- Then, add stress from Push The Limit
- Then, add stress from Daredevil
You could even insert another 'triggered by action ability' right after 'Push the limit', such as 'Experimental interface', which in this case, would lead to the ship ending with 3 stress tokens.
For example, Jake with Daredevil, Push the Limit and Experimental Interface could:
- Focus
- By gaining a focus token, perform a barrel roll action
- As an action has been performed, trigger push the limit
- Perform a boost
- As an action has been performed, trigger experimental interface (nests into PtL)
- Daredevil (nests into experimental interface).
- Then, stress from daredevil
- Then, stress from experimental interface
- Then, stress from push the limit
Then, use "Comms booster" from a nearby epic ship to remove all the stress and give Jake another focus token. Ah! the advantages of playing epic...
The rules are pretty clear in that 'triggered by action' abilities can nest into each other. Experimental interface and PtL can be used together (one action triggers another) and the stress from both abilities apply after resolving both actions.
There is no argument about triggering an action with Push the Limit after expert handling's barrel roll. The FAQ EXPLICITLY SAYS YOU CAN do it.
