Abjuration specialist protective ward question

[daverius]

Quick question:

For abjuration specialists their specialist ability is:

"Protective Ward (Su): As a standard action, you can create
a 10-foot-radius field of protective magic centered on you
that lasts for a number of rounds equal to your Intelligence
modifier. All allies in this area (including you) receive a
+1 deflection bonus to their AC for 1 round."

My question is: Does the deflection bonus to AC last 1 round after use or for the "number of rounds equal to your intelligence modifier?"

[Scipion del Ferro]

I believe it's trying to say that while you are in the Ward you get +1 AC, but if you leave the area it only lasts for the end of the round. However the Ward itself lasts as long as your Int mod. The Ward seems to be immobile as well, but that's conjecture.

[Tanis]

Yeh, it seems to contradict itself.

But what it's saying is that if one of your allies is within 10' when you activate it, they (as well as you) get the deflection bonus for a number of rounds equal to you Int bns.

If your other two allies come within 10' of you after the round that you activate it, they do not get the bonus.

That's how we interpreted it anyway.
