by 5) I was saying that you should leave it as able to target the self and cause EM.
While you may have intended this to be the opposite of Miracle, in actuality it is anti healing [ ]. Darkness and Light are both out of the running because they heal, Water has minor healing and this effect doesn't fit Fire very much. In conclusion Death is the best Element.
I disagree. Darkness fits better because it is messing around with your opponents HP.
Not everything that messes with your opponent's HP is Darkness.
Darkness uses the opponent's resources against them so reversing healing would be a Darkness antihealing measure.
Death is decay and thus poison and reducing max HP both fit in Death.
