Immediate Interrupts and AC

[Trit One-Ear]

Was just glancing at some powers and had a question:
When a power allows you to, as an immediate interrupt, gain AC and/or Ref defense when hit by an attack, does that attack still hit you (assuming the bonus made the difference between a hit or a miss)?

My guess is yes, otherwise what's the point of the power, but I'm not enough a rules lawyer to know if that's the RAW.

An interrupt happens before the trigger; that's the whole point.

So if you use an immediate interrupt that triggers when an attack hits your AC, and that interrupt gives you +4 to AC, and the enemy is now 1 point below your AC on their attack roll, the enemy misses.

No. Interrupts happen first.
Just like magic the gathering

Not since 1999. They're all instants now, no interrupts. But they still happen first.

 

[S'mon]

Interrupt happens before trigger resolves, so can prevent resolution. A well-worded interrupt should be written as "When an attack would hit you, you can add +4 to your AC"

Oh well, haven't played MtG since 1997. I feel old.
