Field of Enervation

Field of Enervation is an area debuff skill available to Force Blader. It shows a Level Down effect in the target UI and uses the listed Level Down value to scale temporary reductions to the target's HP, MP, Attack, Magic Attack, Defense, Attack Rate, and Defense Rate. With the matching blade buff active, it can also reduce DMG Reduction with Fire Blade, Accuracy with Ice Blade, or Evasion with Lightning Blade. It is available starting from Transcender rank and has a max level of 20.

The Level Down part is based on this ratio:

Level Down / (target level - 1)

For example, Level Down 12 against a level 200 target is:

12 / (200 - 1) = about 6%

That means the affected stats are reduced by about 6% before caps and level-difference falloff. The ratio is capped at 50%. If the target is more than 10 levels higher than the caster, the effect gets weaker by about 5% for each extra level difference, reaching no effect around 30 levels higher. The confirmed damage gain comes mainly from lowering the target's Defense, and its reliability gain comes from lowering the target's Defense Rate.
