  You can cast this spell as an Immediate Action when you fail a Climb check and would fall. You can immediately attempt another Climb check as a Free Action at a -2 penalty. Each successive use of this spell in a particular situation increases the penalty by 2. If successful, you don't fall, but you don't progress at climbing.
