This spiral staircase snakes around an ornate support column. Several small precious stones adorn the column and the bannister, inlaid into intricate carvings. As the characters climb the staircase, the carvings come to life, becoming snakes, with the stones as their eyes. The bannister writhes madly. Each character on the staircase must make a SAN check or lose 1d3 SAN. Additionally, each character must also make an STR 12 vs. SIZ check, or lose their balance and tumble off the staircase, taking 1d6 damage per 10 feet fallen.
