Brutal+ Difficulty: Mutation Cost Brackets and Templates
Brutal+ is considered an "Extended Difficulty". That is, missions will take place on the regular Brutal difficulty. However, in addition to the standard mission mechanics, a certain number of random mutators are added to your game. You may queue into random queue on Brutal+ difficulty, as long as the commander you are queueing in with is at Level 15. For Brutal+2 and higher, you will require a person in your party to play.
To learn more about how Brutal+ difficulty mutators are selected, you may watch the video below. The video goes over what Mutation Templates are, how the different mutator possibility counts are calculated mathematically and then how the weightings are rebalanced to be more in line with Blizzard's design intent.
The number of mutators that will be selected is between two and four. Each difficulty level is assigned a total number of points, which corresponds to the total mutation difficulty. The point/mutator brackets for each difficulty level is shown below. Note that the mutator counts for generated Brutal+ mutations are not evenly distributed. You are more likely to see 2 and 3-mutator games than 4 mutator games, as is Blizzard's desgin intent. For more information, please watch the video above.
