I currently have a Ranger12/Fighter4. I plan on making him Ranger12/Fighter8 with Tempest-II/Kensei-I.

I do not currently have Weapon Focus or Weapon Specialization feats needed to quality for Kensei I.

My question: Since I will get 2 feats at level 18 (one from fighter6) can I take Weapon Focus and Weapon Specialization at the same level-up (WF being a prereq for WS)?

It is probably safer to respec a Toughness feat to WF before leveling, then simply pick up Toughness again with the new feat, but I am curious if this will be necessary.

Anyone know?
