These new skills are nonexistent in the original necromancer class skill. These don't exist, not a single one of them. If anything, they shouldn't exist at all since, from the name itself, it seems to make the Necromancer class a lot closer to what Elder Lich Necromancers and Dark Worshipper Necromancers have. There are 2 skills in tier 1, one passive and one active, 1 skill in tier 2, another passive, 1 in tier 3 in which this time, it is an active skill, 1 in tier 4 which is another active skill, and in tier 5 where it has 3 skills 1 passive and 2 active skills.
