These both dictate that in multiple player games you can use prob once during your turn and one other time (during that round).

I wanted an orange post to clarify this if possible as my player group was not aware of this ruling and I was unsure of where to direct them to prove it.

Also I checked another clix site and their wording is pretty much the same.

The 2nd half of the current wording of the power says "once per round during an opponents turn...". So you can only use Probability Control once during your turn and one time during the rest of the round.

That is what I said, and quoted that I had read, but I was told they could still use it once per 'player turn.' So wanted an official guy to post to help clear it up for them.

It doesn't get more official that the rules.

Page 7:
That shows that a round is one time through all players' turns.
That tells you how many times it can be used during a round.

Orange you glad Harpua posted?

I've been waiting to post that little pun since this thread started, pheww...

I was hoping vlad would post so I could accuse him of being smug.

Yup yup, thanks, now my words have merit
