Life and more life.
I don't like Evasion, and really don't like Raider. not sure why anyone would go raider with pathfinder existing.
My frostblades pathfinder has survival layered. First life is obvious priority on gear. A belly of the beast I consider #1 for melee ranger/duelists. But didn't get my hands on one either in reality.
Rumis is obviously good as well.
Passive Skill Tree - Path of Exile
5023 or so hp atm.
Perma fortify with Fortify on frostblades itself. end cry. cwdt+ic. does NOT have vaal pact, so has constant regen. Has pathfinder surgeons, on instant life flask.
Decoy totem. gear hybrid ar/ev.+rumis of iron skin.
As pathfinder, get perma status immune, and 8% elem DR. As well of course flask effect for those flasks, and flask charge gain in combat.
If raider, just drop ambidex, and get phase acro instead. But frankly, you are giving up elem damage, and a ton of defenses from the increased flask up time and effect, and "breaking" rumis/granite, from acrobatics 50%/30% less.
Some people do of course go even further, in grabbing scion life nodes.
This is about what that would look like.
