Ok, so, if you have an FFC below Link, but above a pit or water or whatever, Link can "stand" on top of the FFC, and not interact with the underlying combos. This actually applies to many different combo types, more than I initially suspected when I started typing this post.
However, one type this does not apply to are Damage combos. Is there some reason for this, and is it possible to circumvent it (via script or otherwise)?
