Pros and Cons
This Devil fruit, like all logia possesses the ability to completely evade known damage by fading through it as their element. Also like other logia fruits the user of this fruit can float by turning their lower part of their body into their element. The fruit has the ability to set fires and burn targets but because is already ashes resists attacks from fire and magma very well. Sand will face this fruit at a deadlock. Ice is only relatively effective as though this fruit is somewhat weaker than the Mera Mera no Mi it does produce enough heat to melt ice. Water, Haki, and Kairoseki also have effeects on this fruit but it's major weakness is against liquids which cool down the cinders in the users body and waterlog the users ashesmaking the fruit completely unusable and renering the user halpless, this will happen even if the user has been out in the rain and they will have to dry out before utilizing their powers.
