Once again we turn to Mordenkainen's Tome of Foes for new creatures in store! While standard trolls are already very powerful and dangerous with their regenerative capabilities, this stalker in the swamp had been submerged in the toxins of the Labenda long enough that contact with him spelled disaster for all near it. In the event that it is completely surrounded, it has the option to attack itself in order to burst one of its pockets of venom, dealing a not insignificant amount of damage in a 20 ft cube around itself.

A venom troll’s poison is both its greatest offensive and defensive ability. While bludgeoning damage may have prevented the balloon rats in Zadash’s sewers from poisoning their melee attackers, MToF specifically calls out psychic damage as the only type that won’t trigger a splash of poison from a venom troll. Febron died almost immediately after the encounter started. By the end of the first full round of combat, the party was unable to deal any fire or acid damage to him for fear of harming Beau, who quickly fell unconscious by engaging the creature directly.

Calianna’s Levitate spell proved especially clutch, pulling Beau out of harm’s way before she could fall unconscious to the troll’s poison again. With Beau hovering out of reach, the assault could continue. Since the troll never intended to engage in a straight fight, this was more than enough encouragement to leave the party alone and attempt to escape with one successfully-caught quarry, its regenerative ability taking effect with each retreating step.

Febron’s sacrifice, while fairly pointless, was not entirely in vain. For one, his death signaled to the party to slow down their assault once the creature nabbed Beau’s unconscious form so they didn’t kill her, too. He also successfully brought them to the safehouse, meeting his original agreement. How The Gentlemen will react to an asset’s demise remains to be seen, though considering Febron’s loss of love for the job, it’s possible his usefulness was approaching an end anyway. His 100 gold remains as a tempting draw to the troll’s hovel after the initial work at the safe house is complete, to say nothing of dealing with a potential problem for future smuggling operations.
