Temporary Leveling Feat

[Darkrok]

I'm working up a build that will be 15 paladin/3 monk/2 rogue intimitank leaning on healing amp for survivability / dps character. I don't take my first monk level until 11, plan on THF or sword and board w/o the feats until I hit 12, and plan to have a workable ac until GH.

As part of the build I need to have Weapon Focus: Slashing at level 12 to take Whirling Steel Strike. Before that point though the +1 to hit on a THF character isn't worth the feat. Given that fact I'm trying to decide on a good choice for that level 3 feat to hold on to through level 12. Here's my ideas so far:
- Dodge. It's 1 ac and I'll have a useable ac from level 1-11
- Least Dragonmark of Finding just to try it out.
- Least Dragonmark of Sentinel. Don't need pots for the AC anymore, scales w/ character level, and a +2 to intim to boot.
- Least Dragonmark of Passage. 3 uses of Expeditious Retreat a day? That would really reduce the need to use haste pots on the easier quests and mobility = faster leveling!
- Past Life: Favored Soul. 10 times per day 1d8+1d8/3 levels damage...it's something I guess.
- Stunning Blow: It might work for a stun every now and then at the low DC's of enemies at that point.
- Skill Focus: Intimidate. Not worth it when compared to Sentinel for just a +1 to intim or 1 saved AP.
- Skill Focus: UMD. This is really the other stand-out to me. I'm going to have full UMD ranks, a decent charisma...getting the Skill Focus could really bridge the gap to level 11 when the +5 UMD greensteel item gets opened up.

Whichever of these I choose gets dumped right before I take my 12th level. So which of these gives me the most bang for my buck in getting from 3-11?

When in doubt, take Toughness!

But among all your choices, I'd take the past life feat.

I'm afraid of Toughness as a second feat. Swapping Toughness feats with Fred can be buggy so I don't want to even open that door to a possible LR to fix things.

You can just take Weapon Focus while levelling, the feat is most useful from 1-13 and again at 20 (where To-Hit actually matters). 14-19 it's a waste as most mob ACs are so low you tend to hit things on a 2, but that isn't the case at the low and lower mid levels.

I have swapped a toughness feat before and luckily havent found any problem, yet is good to know it can, just in case.
Glitch or not having one thoughness feat is still recommended, though up to your build.

I'm taking Toughness/Power Attack at level 1 (human). This feat is just a filler feat until later as I'd take everything in the list over +1 to hit. Between ship buffs, twink gear on a TR, pots, house buffs, etc I should have absolutely no trouble hitting things with THF.
