Waterfall Blocks PassageWaterfall Shaft Blocking PassageThe PCs, while following a stone passageway, will come to a ceiling shaft and pit. A torrential waterfall roars down from the shaft into the pit. The fall completely blocks the passage. The waterfall probably originated from an underground river high above and drops very far to a similar river down below. The river passages are completely flooded and the river flows with tremendous force. The torrential fall is hard to pass through physically. The shaft can be anywhere from two to ten foot wide. PCs jumping or climbing the walls through the waterfall will get a +10 penalty on the DC for the check. The waterfall is very cold and completely opaque. Sometimes monsters or traps wait on the other side, hidden from view through the fall. The walls and floor of the passageway, within ten feet of the fall, are wet.
