[sblock=ooc]Heinrich has a haversack, but it still is a move action to retrieve from it. The bonus of the haversack is that it does not provoke an AoO to retrieve, unlike a normal backpack.
It is also a standard action to activate and do the recharge process, so one cannot recharge and cast in the same round.
Pearls are best used between combats when you have spare time. Otherwise, they cut your casting opportunities in half.
If I counted right, it looks like only Drev and Elenka have actions left for round two.[/sblock]
