I am confused. are wooden skeleton keys supposed to have low drop rate? i got at least 1 golden key doing graveyard. but it took me almost 30 runs doing jade oni to get only 1 wooden key. i also didn't get one doing oakheart, main hall, rooftop, hollow mountain a lot of times. how do i get it faster guys?
I'm a few days late to the party here, but the Kraken on Triton Avenue also drops wooden keys. He's probably your best option for farming since it's in a free area, meaning year-round key farming to keep you busy when nothing else is going on.
