It means that your example component with the +10 damage total will have an increased amount of damage on each individual piece to make up for the lesser amounts of pieces needed to complete.
So instead of 5 components, each with +2 giving +10, it will be something like 4 components, each with +2.5 still giving the +10.
Still just my guess from the comments about most of them not being reduced.
i love the unique arts, especially the two rifles (i must find them before b12 release :furious: )
the rare components special coulour is a good improvement too. beside this i’d really like to see a NPC which allows us to remove components from items (dont’ know if it’s planned or not).
I’m still torn if I want to keep playing the Alpha or not. I paid to support Grim Dawn, and that I’ve done pretty well out of. The Alpha keeps making me want more and more and it may spoil the game itself for me.
That said, this is looking amazing; and I’ll probably load up the 12th update as soon as it’s released.
