Let's start with 3 and see how we do. If we kill them while taking minimal damage, we can go up to the other 4. Or should we go with the greater risk yet greater benefit route and go for all 7? Hopefully if I fight defensively I should be able to weather the attacks, and raise everyone's AC so that other people don't take too much damage as well.<br/><br/>Also note that Shield (http://www.d20pfsrd.com/magic/all-spells/s/shield) can only affect the caster :-P
