A Climatic Twist Ending
You guys are engines of destruction. The human and two thieves drop. The sniper behind rushes off into the darkness of Twilos.
But just as you're about to celebrate/interrogate victims/chase escapees...
Theodore, as you're lobbing firebombs and shooting arrows down below, you don't notice the assassin sneaking up behind you on the roof.
A knifeblade rips your throat open, and the half-orc kicks your body down onto the crowd below.
You take 12 from the backstab, and another 4 from the fall. You're at -8 and dropping.
Guys, Theodore is gasping for dear life, thick blood gushing out of his neck and filling back into his exposed, opened windpipe. He begins death throes, his limbs spasming and writhing uncontrollably as the precious second tick away. In about ten seconds, Theodore will be dead.
Failing your poison save earns you 5 more pts of damage. Thak has 1 hp, Az has 4 hp, and Tut has 4, -1, or -6 hp.
...
"You not sing yo' song tomollow!" barks the half-orc from the roof, Theo blood dripping from his razor-sharp knife. "Sing yo' song and mo' of you rill die!"
He turns and flees on the rooftop.
