you mean like specific nodes within a skill tree?
Indeed. One would have to hunt for that specific item that either allocates a node (if it’s a single point one) or ups it with a +N if it is one that allows multiple points.
This could also be interesting if the node would not have to be connected to receive the bonus. It could be considered to allow nodes to go over the cap this way (a 5/5 that increases a skills elemental damage could go to 7/5 for example). But that’s up for thoughts.
The concept I like about this is the diversity - there will be many possible combinations to hunt / trade for and at the same time it would allow trees one could normally not spec. But mostly for when trade kicks in, loot diversity is a good thing to have imo.
