Here’s an upcoming trinket in Shattered Pixel Dungeon that I expect to be pretty polarizing.
Normally when dealing or blocking damage in Shattered, the average result is the most likely one, and the min or max are pretty unlikely. The thirteen leaf clover inverts this, making extreme results more likely than the average. This makes combat much less consistent, for better or worse!
So the way Shattered currently works is that the average numbers in a range are more likely to appear, it’s like rolling 2d6 vs 1d12. The clover will steadily cancel out and then invert that depending on how highly it is upgraded. At max level, low and high rolls will be a lot more likely than the average, somewhat like rolling 2d12 and picking the one that’s furthest from a 6.
