Stirge Cave

A ladder clinging to the south face of the spire ends at this level, which is 160 feet above ground.
The pterafolk don’t use this cave. However, the chamber in the northeast corner is the lair of nine stirges, which cling to the 10-foot-high ceiling. They don’t react unless multiple characters enter their lair or someone brings in a torch or other open flame, in which case they attack.
Six months ago, an explorer who was captured by the pterafolk managed to escape and descend this far before falling prey to the stirges. Her desiccated corpse is slumped along the northern wall of the stirges’ chamber, and the glint of gold and gems can be seen through tattered clothing and a rotting purse.

Treasure

Characters who brave the stirges and search the dead explorer can recover 15 gp, a gold and carnelian ring (60 gp), and two onyx figurines representing chwingas (50 gp each).

Reaching Level 3

Clinging to the west face of the spire is a ledge, above which is a ladder leading up to level 3. Whenever a character crosses the ledge, roll a d6. On a roll of 1, a sudden gust of wind threatens to blow the character off the ledge. The character must make a DC 9 Dexterity saving throw. If the saving throw fails, the character falls to the base of the spire unless he or she is secured by ropes.
