Like before, there are 3 trees you can put points into, but how you go about putting points has been more streamlined. First off, in each tree there are 6 levels of masteries. In each level, there are 2 masteries you can choose, except the final one which has 3.

Levels 1, 3, and 5 can have up to 5 points split between the two mastery options. For example, you can have 2 points in attack speed and 3 in AP, or you can put all 5 into 1 skill. You cannot put more than 5 points in any of these 3 levels.

Levels 2, 4, and 6 can have only 1 point put into into them. These "single point" masteries are generally really strong, with the level 6 mastery (dubbed keystone mastery) being extremely good.

With you way the masteries are set up, you usually will be running 18 points in one tree for the tier 3 "single point" mastery, and then 12 into another for a tier 2 "single point" mastery. There may be some cases where may want 2 tier 1 "single point" masteries instead, but I don't think you'll want that too often.
