Steps:
"Jigs" are a category of Dancer job abilities. Their duration can be enhanced through two items in the Legs and Feet equipment slots.
It's the same two items, just different qualities/upgrades. Here is the full list.
Legs: Etoile Tights, Etoile Tights +1, Etoile Tights +2, Horos Tights, Horos Tights +1
Feet: Dancer's Shoes, Dancer's Shoes +1, Maxixi Shoes, Maxixi Shoes +1
The highest quality give a duration bonus of 45% (legs) and 40% (feet).
When these two items get paired together they incur a penalty, and the overall duration of jigs cannot exceed a 50% bonus of the base duration.
Considering there are already many other abilities that last longer than base duration +50% and considering this has no affect at all on the game's balance, I think this is a small oversight of the developers and that this limitation should be increased or removed completely.
