I'm guessing it is a first life toon? My Main is on his 11th life never repeating a build, and i've done 2 lives since the enhancement pass...Helf hasn't really been nerfed at all. It is a bit annoying that you need to take human versatility boost in the core line, but the saves boost got a buff making it so you can't fail on a 1 while active if your save is high enough so i usually take that
.
As for your build ideas, ranger splash assassin tier 5 sounds good...just keep in mind that Assassinate DC is based off rogue levels not character levels. Cleric dill is always nice unless you plan on having the UMD to scroll yourself, in which case pally dill is the way to go
.
Melee divine with scimies and rogue dill...that could be interesting with the new warpriest line
. Maybe splash some monk for extra feats (as divines are a bit feat starved for twf on their own) and you get evasion and stances
. If you do take the monk i'd consider pally dill there too for the extra reflex save, but rog is great for the SA damage
. er...just now noticed neutral. so scratch splashing monk...maybe 2 fighter splash?
I cannot help with druid as i have not had time to try one of them yet, but I know as far as splits that will work well with helf. pure sorc with FvS dill or pally dill. any tukaw varient using fvs dill instead of reconstruct. If you have some repeaters lying around 6arti/12rogue/2 anything else does immense pure physical ranged dps. hopefully i've been of some help >.<
good luck and just make sure to have fun.
