Apply "Nightmare" effect to target for 4 turns: When the caster takes damage, the target of the nightmare takes that damage equally. (Nightmare effect will not be triggered if the target's HP is in an excessive healing storage)
If a target already in a nightmare is applied by a nightmare again, it puts the target into a Nightfright effect and resets the duration.
Every damage dealt to allies will be dealt to the target of Nightfright equally. (Nightmare effect will not be triggered if the target's HP is in an excessive healing storage)
If the "Nightmare" or "Nightfright" effect is dispelled, the caster recovers a large amount of mana immediately.
