n interesting build ive come up with is Half-elf Seeker|Ranger/Skald go 13,0,0,0,20,13
use Arcery Mastery feat to gain Cleaver Shot at-will, song of serendipity as Dilettante, and Grasping Spirits as Seeker at-will. Use Cleaver shot to actvate Grasping Spirits, and on a hit the target is slowed and cant shift till end of its next turn, slid 2 squares (or prone, or slowed SE), and an ally gets +2 to hit. Seams a good was to kite an enemy indefinatly, esspecialy if you pump your slide distance.
Also for 1st level encounter, Rangers Fox's Cunning is an IR that lets you shift and make a basic with WIS mod power bonus bonus to attack when an enemy hits you with a melee attack. No Clever Shot, but works with Grasping Spirits and Song of Serendipity.
