Since getting the Black Chocobo Suit from the New Year's event, I've noticed a very strange thing: I'm getting better at Chocodigging while wearing it.
Before January I was an A10 chocodigger, had been an A10 chocodigger for years. I'd always buy around 250 greens, and would use a silk shirt to double my chocobo's endurance to get the full 100 digs plus the 100 digs that would be free due to the shirt.
With the Suit, I am now limited to the 100 natural digs per day. It always did take me around 250 greens to get to digging exhaustion per day, and with the suit, you start around 40% dig accuracy.
Lately, however... I've gotten way more accurate and nothing has changed, at least equipment wise. It seems that I'm around 65% accuracy with my chocodigs. Perhaps the suit allows you to progress past the natural cap of A10 chocodigging and into heretofore unknown levels of chocodigging mastery? That'd be my only conclusion, and why I am making a post here. Can anybody else confirm the increase in chocoskill after A10 while using the Black Chocobo Suit?
