 * Combat timers requires to be revisited
 * Clearly seen one peon died from Shadow Fissure, doesn't work because health regenerates,
   it should regenerate in case of other spells, no sniffs with Wild Shadow Fissure
 * Dark Spin gets interrupted after first tick
 * Death Coil is a buff instead of a debuff
