Ultimate Radius is a suffix that turns up on Relic, but only on gear tagged relic. It gives kitUltimateRadiusPercent: +8% to +9% at its lowest step, +24% to +25% 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 (kitUltimateRadiusPercent), and it is what puts Breadth, Magnitude, Enormity, the Horizon and the Heavens in an item's name — so you might pick up a Wand of Breadth.
No Unique carries it at a fixed number.
