Item description:

When you are walking up or down diagonally on stairs, you do not receive any damage from poison or healing from Tintinabar. Also, certain event bits do not reset as they should upon taking a step. This patch corrects these problems along with another walking problem: if Terra is walking inside Zone Eater Cave when the ceiling falls, she’ll take an extra step forward, which can lead her to places like off a ledge and past an exit and off into the wild black yonder.
