"Reversed" spells like that scream EHP, to me. So Cleric.Does the spell-tree of: Inflict Wound -> Blight -> Contagion -> Harm feels more druidic or cleric-y to you?
Sure, accelerate (or slow) healing or aging or disease (recover or succumb), for instance. But negative energy & necromancy are strongly associated with Undeath, which is antithetical.The whole destroy life/cycle of life thing speaks Primal to me, but the reverse-Jesus thing also says ''dark cleric'' to me. Conundrum.
Wizards defy nature more than Cleric or Druid. Though I'm strongly of the 'Druids are not Hippies!' persuasion (even though RL neo-pagan Druids often were exactly that), Druids have always seemed to work more nearly with nature (and, sadly, have no particular power to stop undead, beyond burning them), Clerics to claim divine dominion over nature (but not defy it perversely, unless Eeeeevil), and Wizards to embrace the outright unnatural with enthusiasm (witness all those monsters they seem to make!).
