Help with pure ranger twf tempest build

[Set]

Hi, I have a level 12 pure Ranger that I haven't played for a while. Since I already have a few other ranged classes, I'm interested in making a TWF Tempest Ranger. I plan on making Dexterity my main stat since I can use it for hit and damage with light weapons.

I wanna be self sufficient with great twf damage, decent heals, evasion, and the Tier 5 Tempest Improved Evasion-like enhancement (so I can just blow by traps). I am Drow btw.


What Feats should I take?

I'm guessing: Power Attack, Dodge, Mobility, Improved Crit/Slashing (Scimi), Empower Healing?????

Does Cleave work with TWF?

Thanks
