I have tested this countless times, and it really cripples my plague cro build. The tool tip reads: applying a major or minor debuff to an enemy applies star venom to them for 4 seconds.
There have been numerous complaints that none of the necromancers' skills/ debuffs/ status effects proc the tool tips of sets. Another example would be elemental succession not being proc'd by blast bones. Any help from the devs on this would be appreciated since necromancer is close to my heart. Hate to see that class suffer in so many ways!
