Some Necro scaling questions

So my question is about scaling necrotic damage in a few areas:

The flat necrotic damage that you can get for minions in the passive tree, can this be scaled by minion necrotic damage affix?

The Necrotic damage buff that Dread Shade provides, it has flat damage as well as % increased, do either of these scale off necrotic affix? If yes, would it be minion necrotic or player?

Bone curse can be switched to necrotic damage, same question as above, would giving myself increased necrotic increase the damage from this?


Yes, minion necrotic (or player if it’s affecting the player).

Player necrotic damage would affect that since its a player skill.
