What a set pays, tier by tier
Every number a set bonus grants, at each of the six tiers. Which slot carries which of these, and which class group gets what, is on the item sets page.

Most of them stop growing at tier 4 and tier 5 buys uniques instead; tier 6 lifts the caps again. A tier is the colour of the item's name, and a vengeful or masterful item counts one higher.
