In Dragon Compendium, there's a race called the dvati. They're twins. They're pretty good as bards and rogues as they have bonuses to Perform and to flanking. That LA +1 isn't so great though. Even though they're twins, they share the same soul so if one dies, they both die. It's even easier for them to go down when they're sharing the same hit point pool. As well, if they're a spellcaster, they share spells. So that got me thinking. If they share spells, and a pearl of power would get them back their spell, after one activates it, what about initiator classes like warblade or swordsage. If it requires a standard action or full round action to get your stuff back, could you not technically have one twin do that, while the other one readies their next returned maneuver? That'd make for a heck of a combo.
