This skill allows reaver to take the full advantage of the skill blood
harvest. When moving scythe or a weapon of choice in full motion, a skilled
reaver doesn't break the skill from impact but instead chooses to use the
ongoing rotation motion to use the strike power to harness the leftover energy
to something useful. As reavers do not possess the level of plant knowledge
that an experienced healer specialized in herbal remedies would, reavers can
only harvest a few plants that are recognizible to them thus limiting them to
harvest only wheat, yarrow, spinach, reed and raspberry.

Not everyone will feel the need to train this skill. That's fine. Those of you
who want it, now have that option.
