Do minion duration nodes affect the duration of spectre abilities?

Hi everyone. Hope you are all doing well :)

I was wondering, do you know if the minion duration nodes on the passive tree also affect the duration aspect of certain skills used by spectres (buffs, charges, curses, any ability that has a duration)?

Or if the minion duration nodes only affect the duration of the minion itself and has no association to the duration of their skills?

Any help would be appreciated and thank you so much :)

I don't think so, but linking Increased Duration to your Raise Spectre gem should do the trick.
