Doedre's Undoing what scales

Hi all just looking to see if anyone has tested what all works on this for scaling.

What i know works:
Increased Spell damage works
cast speed
Area Damage
Increased Chaos Damage
Scaling Int

What i don't know
does Extra Chaos Damage work for this?
Hazard damage? supposedly some hazard area of effect nodes don't effect it?


Its really hard to tell cause there is no tool tip damage for this being a support!
