Thank you very very much for your answer.
Yes a good gear combination could look loke this: Cabalist, Level 100 (GD 1.1.9.4) - Grim Dawn Build Calculator
You said: Will of Rattosh reduces resistance of enemy vitality damage
Yes that is true. As I would like to do chaosdamage I thought using the Skellies from Raise the dead could be more helpful as they reduce all resistances for 24% compared to reducing 25% Vitalityresistance “only” from Will of Rattosh.
Another question. Will the Vitality Damage from Will of rattosh converted to Chaos as well because of the ring Mythical Voidwhisper Band?
I will have a look at your notice regading Marrow Band / Myth Spiritbinder rings
