What if u leave the node as it is and instead make a unique item lets say a belt, that can only be found in specific Boss areas Only, (The boss only maps that drops) "(Oh and btw, buff those bosses, they're a joke)" And that belt amplifies that node like this The node Exorsist gets three times the effectiveness
Also, imagane other uniques Like this that drops in a similar fashion, from unique bosses that in a way modifies a major Node in a creative and fun way.

Also, off topic but relevant: Please buff map density, im in high tier champion content and the density is a joke, super small packs and bearly any rare/elite packs.
