"The item does not trigger on single target damage over time abilities, such as Torment, or non-damaging abilities such as  Cocoon . It is unknown whether this is a bug." It clearly states in the item description that it doesn't work for periodic damage spells, i.e spells that deal damage over a period of time and only works for spells that deal damage.
