Combat Challenge questions

[psyronin]

There are a couple of things about Combat Challenge that I'm not sure how they work. I'm hoping some of you might be able to enlighten me.

1. When a marked enemy shifts or makes an attack that doesn't include you, you get to make an attack as an immediate interrupt. Are these attacks limited to 1 per round or 1 per turn?

2. I have the Shield Push feat. A marked enemy attacks a party member next to me. I hit the enemy with my Combat Challenge interrupt and move it away one square and now the enemy is not adjacent to the original party member but is adjacent to a different party member. Does the enemy lose its standard action because it got interrupted, or can it switch to the new party member?

Thanks in advance.

From what i understand from the RAW, in that case your Immediate Interrupt cancels target's attack.

"If an interrupt invalidates a triggering action, that action is lost."

I'm with Z here. This feat makes for some interesting situations, especially since it can be triggered by a shift or an attack. Makes maneuvering around the fighter more difficult, as she can force you to start your shift from a different (possibly more distant) square.

Keep in mind, though, that a creature with reach may still be able to complete an attack that was interrupted by this push.
