Planar Infusions feats (from Planar Adventures) require a connection to the plane in question, usually from being there for an extended period of time or through prolonged contact, etc. I don't see any such requirements for other generic Conduit feats, as they only list ranks in a skill as a prerequisite. Do they rely upon Planar Infusion feats? For example, for a character who has had no contact with the plane the Maelstrom and does not have the Maelstrom Planar Infusion feat, can they choose the Malleable Form Conduit feat?
The infusion feats require prolonged contact.
The rest of the conduit feats, as listed by their prerequisites, dont.
That said, I don't think most are that good.
Malleable Form is good for squeezing, but how often does that happen?
Wanderers Fortune, however, can get you Freedom of Movement once per day starting as low as 3rd level. This I see as being quite useful.
Wind Leaper looks great for my ninja. His Acrobatics is very high, and this lets him jump really high.
