How Hero Siege star level scaling works in Hero Siege Builds

Hero Siege Builds applies a +8% multiplier per star to eligible item affixes. The gear planner supports 0 to 5 stars so you can compare upgraded items against the rest of your build.

Exceptions

Hero Siege star level exceptions

Runeword implicit stats and +X to all skills are not treated like regular item affixes, so their bonuses stay separate from star scaling.
