I guess what they were going for is they snatched people fast, so all their gear is on them.
Still, they could have it where starter gear is nearby. There are chests, tables, a few dead imps... Stuff could be all around that starter area.
Either way, all they'd have to do is have Lae'zel and SH's armor and weapons off limits to take. Potions and other are not off limits.
Or, have SH and Lae'zel computer controlled so they might help you with a potion or something if the AI seems they need to.
I think AI would be best, actually so Lae'zel tries to keep you moving towards the helm. Her objective.
But, again, Zalk's sword would be nigh impossible to acquire. Only party of 4 customs would likely get it.
