To answer my question please from another thread.
From what I can tell the first cast should be max damage and stacking it after 1st can be min damage min sp but still give a max damage result triple stacked? And u just keep casting minimally to keep it going?
Does that go for wearing a lore item too? So after the first cast with lore on as long as I keep the DOTs going I can take off my lore item and even some spell power items??
