Thanks for adding Fallon and Krug to the character thread, but feel free to up them to 6th level. You deserve it!
Fallon distracts the minotaur momentarily from his ceiling perch, allowing Verakka to score with both blades (21 damage). Malikar adds two strikes from his shortswords, dropping the huge brute (26 damage).
Krug hits the stunned lamia with a crossbow bolt (7 damage), but the bound lamia shies away from Titus' lazy strike (rolled a 1).
The only remaining foes are your captive lamia and lamia which is stunned for nine rounds, so I'm assuming Dyrnas holds his lightning bolt. Combat is effectively over. Do you kill the other lamia or take a second captive?
The stunned lamia appears to wearing fine bracers and two rings (one bone, one metal). He is also carrying several potions. The dead minotaur has a huge masterwork greatsword and a single potion.
