Mercurius

Name: Infernal Eclipse
Rank: S
Duration: 4
Cooldown: 5
Description: With nothing but a thought to activate the ability, Raven’s chain whip gets covered with dark flames (not as dark as God slayers but just really black like a raven’s feathers) outlining the entire blade. It cannot be put out with water or is not affected by it since they aren’t ordinary flames but the fire of Kaito’s spirit. However, they do have a weakness and that is to light, especially the purifying type. When hit with this flame, no matter what material it is(except light) it will catch fire and deal basic melee damage and then 1.5S rank damage over time. Hitting whatever that is on fire with an A rank spell(B rank if light) will extinguish the flames.
Strengths:
-Unlike ordinary fire, it isn’t weak against water
-Does damage over time
-Raven cannot be hurt by the fire since it’s her father’s spirit
Weaknesses:
-Weak to light, especially holy light
-Can hit allies if not careful
-Flames on other objects can be extinguished (or will extinguish itself after 3 posts)
-This ability obviously cannot set fire to fire itself. If equal in rank, they will cancel out.
