SRD said:If You’re Pinned by an Opponent
When an opponent has pinned you, you are held immobile (but not helpless) for 1 round. While you’re pinned, you take a -4 penalty to your AC against opponents other than the one pinning you. At your opponent’s option, you may also be unable to speak. On your turn, you can try to escape the pin by making an opposed grapple check in place of an attack. You can make an Escape Artist check in place of your grapple check if you want, but this requires a standard action. If you win, you escape the pin, but you’re still grappling.
I have a grappler character in my game, and we had a bit of a dispute last session regarding pinning. He had grappled a druid with an active Produce Flame and successfully pinned him. The druid's turn came up and, after reading the above, was inclined to rule that in the absence of a glossary term regarding immobile (and due to the fact that the creature is not helpless), the druid would only be restricted from moving the grapple with an opposed grapple check, and could apply the touch spell currently in effect. He disagreed, and we quickly came to the agreement that since it was a touch spell, the druid could use it, but otherwise probably couldn't, and that we would check the rules in the interim. I'm looking for verbage one way or another detailing exactly what is meant by "held immobile", and what actions it prevents.
I'm inclined to allow attacks by touch spells and natural weapons, at the very least, due to the fact that the quoted text indicates that you can attempt to break the pin with an attack action, but does not specify that you must do so in order to otherwise act. Is there clear text one way or the other? Thanks!
