Just a Scarecrow: While the Harvestman remains motionless, it is indistinguishable from an ordinary, inanimate scarecrow.   Mimicry: The Harvestman can mimic the voices of any creature they have heard. A creature that hears them can tell they are imitations with a DC 16 Wisdom (Insight) check.   Reap and Sow: Attacks made against any creature with the Frightened condition are made at advantage.   Crowstorm (Round 2): 1d4 Swarms of crows appear on the battlefield. These crows behave identically to the Swarm of Ravens stat block, however their Beaks attack causes the creature to make a DC 13 Wisdom saving throw or become Frightened until the end of their next turn. If they succeed against this saving throw, they are immune to the Frightened effect caused by this attack.   Bountiful Harvest (Round 3 or become Bloodied): Any creature hit with the Harvestman's Claw attack must make a DC 13 Wisdom saving throw or become Frightened. The creature can make another Wisdom saving throw at the end of each of its turns to remove the effect.
