I have seen people on this forum read that line of text as:
- you get an increase in intelligence, with all the effects, included increased skill points
plus
- you get a specific maximized skill.As written and read in a vacuum it is even plausible.
Nowhere it say that you use the new skill points to pay for the linked skill and it is weird that if you have point in that skill they overlap.Clearly it is not RAI, RAI it is that you spend the new skill point purchasing the linked skill.
It's actually been clarified with a FAQ for some time now. The Headband's associated skill represents the skillpoints you would have gained. The Headband is an exception to the normal rule of Int+ items granting retroactive skillpoints, which is why I entirely disagree that other Int+ items should have specific skills associated with them. They grant skill points and the player should note which skills he puts those points into, so that when the item is removed the correct skill points are lost.
