Build idea is to get a many spammable summons as possible, and buff them as well as a limited gear build can manage without sacrificing survivability on ultimate.
getting 8 summon skeletons, 6 from revenant, and 3 from bonescavangers gloves.
along with mondragon pact and soul harvent adding damage and having as much of that converted to vitality as possible and reducing vit res with spectre wrath, devouring swarm, will of rattosh, and acid spray.
any suggestions on how to improve this without specific non-faction gear would be appreciated.
I have no idea how to make that work or if it is even possible. But if you are going to focus on vitality, you might want to consider Dying God and also more offensive ability (OA) if you want to do dmg yourself. And your pets might need a bit more pet bonuses too.
