PC's lose hp on a failure albeit not many considering their level, and before each new round of skill checks they must make a CON check or suffer a level of exhaustion. This seems kinda silly. IF we assume most parties will comprise 3-6 PCs that means there would be, at MOST two rounds and most of the time only one. My party scored one success and three failures, then retired for the day. They rolled HORRIBLY. Next day they scored the three successes right off the bat and the task continued.
They have a druid skilled with an herbalist kit who has done some potion concocting work. This, combined with our cleric's knowledge of wild beasts, including the ettercap, gave them the insight they needed to make the potion. They'd been studiously avoiding them during their pursuit of the hind but knew where to find them now that they needed them. This woulda been a medium difficulty encounter but the ettercaps got lucky. TWO of them managed to restrain two party members, making it a hard fight. One of the E'caps was quickly put to flight making it a 3 on two combat for a couple rounds until the druid and wizard got free of the webs. Two more rounds of combat vanquished the foe with the Battle Master being reduced 50%.
Poison sack harvested (on second try - the party has a new appreciation for their missing Ranger) and anti-venom salve prepared. Trained falcon earned as a reward, as well as all living expenses for the month being covered. Party returns to the real world next session but will revisit the village of Kalogeros in a month when another party member steps away from the table for a few weeks.
All in all the party is enjoying these diversions and appreciates the variety provided so far. Next task is another combat pillar with a little social interaction. Task #5 will present some outstanding problem solving opportunities. Still recommend if you need an interesting drop-in or wanna play a dozen or so session campaign running from 5th to 8th level.
