Hi there! I'm hoping to gain some insight on a build I'm currently working on for the upcoming campaign my friends and I are having. I'm stuck being the party's trap disabler again, but this time I came up with a new build that will work both for me and for the party's needs. We're starting on third level, and I plan on taking my first level in scout and the next two in ranger to start off. I'm taking the able learner feat so I can always have disable device as a class skill (plus I need it for my eventual prestige class) and since I'm human that will leave me one more feat to take at first level. Third level will be taken up by the swift hunter feat which allows the scout and ranger levels to stack for favored enemies and skirmish.
My question is this: What should I take for my last first level feat?
I'm considering either taking Iron Will or Scorpion's Resolve from Sandstorm since my DM is letting us use that book. Considering I'll have +0 to my will save (not counting whatever my wisdom modifier would be) I'm hoping to do something useful to boost it until 4th level when I'll actually gain a +1.
Iron Will would obviously give me a +2 to my will save flat out. Scorpion's Resolve would give me a +4, but only to will saves made to avoid mind effecting spells and abilities. While this is a large portion of the "scary" effects you need a will save for (thinking Phantasmal Killer, Hideous Laughter, Dominate Person, etc.) it leaves a lot open.
Do you guys think it's worth it to have that +4 for those, or would it be better to have the +2 all around? I'm leaning more toward the +4, but that could be because I was almost Phantasmal Killer-ed to death last campaign when I was disabling a trap :P Feel free to suggest any other feats too since I was also tossing Dodge around, but to be honest the will save lack is a concern for me.
