Return Damage is a suffix that turns up on Off Hand, but only on gear tagged arcane_echo. It gives kitReturnPercent: +10% to +12% at its lowest step, +38% to +40% at its best — and you need item level 116 before the best one can appear at all.
It comes up at weight 5 when the game rolls affixes, never doubles up with another affix that does the same job (kitReturnPercent), and it is what puts Rebound, Recoil, the Undertow, the Riptide and the Tidewrack in an item's name — so you might pick up a Wand of Rebound.
No Unique carries it at a fixed number.
