Execute Threshold is a suffix that turns up on Off Hand, but only on gear tagged shadowstep. It gives kitExecutePercent: +5% to +6% at its lowest step, +14% to +15% 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 (kitExecutePercent), and it is what puts Execution, the Headsman, the Guillotine, the Reaper and the Last Breath in an item's name — so you might pick up a Wand of Execution.
No Unique carries it at a fixed number.
