Kain just recently leveled to level 5 (he was Ranger 4 beforehand), and I was deciding whether to take another rank in Ranger or start Rogue (ended up taking 1 Rogue).
Just to see, I took Ranger, and I was able to take an extra feat, either another Favored Enemy or this Daylight Adjustment thing that, according to the description, is supposed to only be for Dwarfs, Drow or Gnomes (something like that). Kain is human, so it might be strange to have this feat show up there.
On another note, Kain took Favored Enemy in Giants at lvl 1 but I don't get the +1 attack bonus against Ogres. Are Ogres considered "Giants"?
