I just made up this build I'm naming.. "Unbalanced", which fits in more ways than one.
1sorc,1ranger,18monk ELF
1) Drop down and Kukan-Do you, ranged, high DC.
2) Abundant Step to a good spot away from you.
3) Whip out their STR or CON damage bow.
4) Manyshot!
5) They have Slayer Arrows too.
6) They also have Improved Evasion.
7) Grasp the Earth Dragon (stun immune)
8) Monk Spell Resistance!
Instruction Notes:
At 1sorc take "Sorcerer Energy of the Dragonblooded I".
Then take 1ranger for Bow Strength.
18monk, using feats for getting Manyshot.
Kukan-Do: (DC = 10 + Charisma Modifier + your monk level)
That's a 28 DC minimum.
At level 20 you're an AA w/ Slayer Arrows.
