Snake Sidewind (Combat)
Benefit: … Whenever you score a critical hit with your unarmed strike, you can spend an immediate action to take a 5-foot step even if you have otherwise moved this round.
Does this mean, that you get an additional 5-foot-step, even if you took a 5-foot-step in your last action? Or does this work with other kinds of movement only?
I think any movement is fine, even a 5 foot step. Although, it is an immediate action, so you can only use this ability once a round (b/c if I don't say it, someone else will).
