How do players determine their ability pools and expertise?
The players roll 2d6 for each stat (so 3 times) and then choose which stat they want to have as their highest/lowest. Similar to DnD where you roll your ability scores and then decide which skills get which. For expertise you get 0, 1, and 2 so you have to choose which ability to give the 0 in Expertise to, which one the 1, and which one the 2.
