With the release of 2.2.0 Patch Notes, Blizzard has revealed all Main and Modifier Effects for the 24 Boss Powers coming with Diablo Season 8. These will be farmed throughout the season similar to the Season 7 Witchcraft Powers, and have two components, a Main effect, and a Modifier effect. The interface for these powers has four slots, 1 Main and 3 Modifier slots. Depending on which slot a power is socketed into, its effect will change, so pick carefully!
