The curse ability from dead sorcerers is over powered. It should not be allowed for a mob to be able to kill any player, with appropriate gear, of one single attack. Even after adding a warning before the curse, it is of no help since the magnitude of damage is still the same. Either move the ability or change it to Fireball, Frost Bolt, or give them an Arcane Shield, but not an ability that is able to kill anyone of one hit.
