A quick rules question. Am I correct in thinking that since Ghaazala had to drop her chain to avoid being tripped, and she has no move actions left this turn, she is unable to make an Attack of Opportunity because the wights are out of her unarmed range? She can pick up the chain at the beginning of her next turn using her move action, but as for this round, she doesn't have the ability to make AoO's if she's unarmed and they're out of her range.
