Average damage is tested on small (e.g., Lowe) to medium targets (e.g., Wooden Doll) with realistic positioning.
Maximum damage for large-hitbox skills may be unattainable in-game and is estimated.
Timed buffs are included only if they alter skill function or appear in the tooltip; permanent boosts are always included.

As the amount of HP absorbed from a target is based directly on how much Impact damage was dealt, anything that increases or decreases your damage will also affect the HP absorbed.
Assuming no sources of MP cost reduction, as the skill costs 40 MP to use and can only absorb 20x2 MP, this skill cannot be used to recover MP, as you merely gain as much as you used.
You can only absorb HP/MP from 1 target at a time.
