Unexpected Visitor

[Investiture of the Dark] also gives him corrosion properties. It was the same as the [Negative Land]. It was a field-type spell that debuffs all enemies that entered the field. It corrodes the enemies decreasing their movement speed by twenty percent and slowly chipping their health until they die. It also decreased the enemies' resistance to the dark attribute by twenty percent and rendering the light attribute's effectiveness by twenty percent.

Within this field, Souta could detect all the enemies and know what they were doing. It was just a bonus effect since he could already detect them through their blood. The decaying effect of this spell could render all the enemies' dark attributes to zero percent if their elemental power was two stages below the user.

In short, Souta would have absolute control of darkness within this field.
