I assume she rolled nat 1 and it is good chance she fumbled her grip and fell then (as there is DC for progress and then DC on holding on). Usually nat 1 has classically given as fail to hold onto wall/something with climb check.<br/><br/>Also even if I know Mysteria is more into lesbian stuff, catching a hot girl from falling on ground gives cool points to Tashi ;). But I almost suspect the real target is disguised as the dropped limb in the water than the guy standing on the bird anyway.
