Witcher gear set bonus

I'm playing the Witcher 3 and i just retrieved all "Griphon Witcher" schematics. I crafted the 2 swords and 2 pieces of armor. I was expecting to receive a set bonus.

Is there a set bonus? Am I missing something?

There is no bonus set, but green items can be upgraded to better versions of themselves latter. Don't destroy them when you find a shiny brown sword !

Yes, there are set bonuses as you can CLEARLY read them when you look at the set pieces in the crafting page. ALTHOUGH, activating those set bonuses requires you to upgrade your set pieces to the grandmaster level.

There is no bonus for wearing a full set of armor.

But you can get a skill in your character Menu, which will add you a bonus depending if you're wearing light, medium or heavy armor.

So in a way a full set (since it is of the same armor class) will still give you some benefit.
