Chill strike
wizard attack 1

Target: one creature

Attack: Intelligence vs. Fortitude

Hit: "2d8 + Intelligence modifier cold damage, and the target is dazed until the end of your next turn."[PH:159]

Miss: "The target is slowed until the end of your next turn."[Dr401:54][U:12/2011]

Chill strike is an encounter power available to wizards at 1st level.

The "Class Compendium: The Arcanist" article in Dragon 401 added the evocation keyword, and the slow condition on a miss to chill strike. Previously, chill strike had no effect on a miss. The December 2011 update finalized these changes.
