Are there any held items that emulate the 'Serene Grace' ability?

Question

Just as the title says—are there any held or usable items from any generation of games that increases the chance for some moves' secondary effects to occur?

And if so, does it stack with 'Serene Grace' somehow?

Answer 1

Unfortunately, no, there are no items that replicate Serene Grace. This would be extremely overpowered, if it was in existence.
