I think the imbued cooldown and duration items are really cool! I also think that there should be more items that build out of lower cost items. Combining these two ideas together, the first two ideas that came to mind were:
An upgraded Extra Regen that would give you a small hp regen boost each time you used the associated skill
An upgraded Monster Rounds that would increase the damage that an associated skill did to npcs.
While im sure there are many other possible applications for this idea, these are the two that sprang to mind.
