When to buy & tricks
Superior Duration adds a flat duration boost to every ability and item you cast, so stuns, slows, beams, walls, summons and buff fields all last noticeably longer. Slot it on heroes whose power comes from keeping an effect on the map — long lockdowns, channeled ults or persistent zones — where extra seconds matter more than raw spirit.
