Thorn whip
druid attack 1

Target: one creature

Attack: Wisdom vs. Fortitude

Hit: "1d8 + Wisdom modifier damage, and you pull the target 2 squares.
"Level 21: 2d8 + Wisdom modifier damage."[PH2:85]

Thorn whip is an at-will power available to druids at 1st level.

It is ranked as a poor choice, as it is unremarkable for an at-will power and is outclassed by Savage rend. However, it is of use against skirmishers (as it targets the fortitude defense), is the only at-will that targets fortitude, and can be used on enemies that you can't directly reach.[1]
