While in town to buy missile weapons (after fleeing from the tower) the team recruit the barbarianess Mama Cori and warrior Talarian Design to fill out the roster, dropping what's left of Allison and Dalian with the Temple of Ben Kingsley. Since no replacement for Thorgrim (NPC party slot only) is found, his corpse continues to be dragged around which is kinda strange in that it helps carry things.
Anyway, now armed properly the team returns to the tower and with Mama Cori acting as "winch person" (staying behind to operate the lift: the politically correct verion) they return to the slab that blocked their return on level 2 which happens to be easily openable from the entry side. It simply closes again when the party passes through - trapping them again. If that was designed to piss people off, it's doing a good job.
They find the gnoll making mage and his new gnolls right where they left him. This time everyone focuses fire on him first, and Cooper manages to land an arrow right into the mage's face: killing him instantly. The rest of his creations are easily dealt with afterwards, and it turns out they were guarding the next stairs up.
You look familiar...
There on level four, a familiar wizard awaited. Toranor!? AGAIN? This time he also summoned ghouls to the fight, and cast terror spells which sent all the party fleeing. All but Cooper, who got knocked out by ghouls (continuing his running gag with them), and Talarian who ended up soloing the entire encounter and with 4 hit points left - somehow won! Not bad for a first day on the job.
