Effect expiration - brain fart

[Olodrin]

I feel like I'm missing something, so I hope you can help me.

My character has the feat Psychic Lock, which applies a -2 penalty to the monster's next attack and then expires.

Can someone write out the effects syntax for me?

In case you didn't know, the I've found the best way to figure out effects is to let the ruleset do it. To figure out the syntax for you I dropped the feat into Situation Powers on a character sheet and then modified it to work on the target instead of self and then dropped the effect on something in the combat tracker. The syntax is: [ROLL]; ATK: -2

That's... fantastic!
