Reap the Harvest is an at-will power available to druids at 1st level.
Primal energy shrouds your foe in the aftermath of your weapon strike, attuning itself to an ally's follow-up attack. The next strike that misses is like a pass of the reaper's scythe, cleanly cutting through your foe's defenses.
