Hey, I would like to know what is the best place to farm for King Parsley as I need amber from it. I have just started Azteca and I am in Saltmedow Swamp. If anyone knows where is good place to farm for it please tell me.
As for how many you'll need, you can start with 1 or 2 and end up with dozens in no time. They reproduce like Dandelions.
Unfortunately, the drop rate on Amber is way over-hyped on these plants. It's something like 1 in 30 from the regular plant, but higher for Ultras (or so I've heard). I got annoyed spending months on KP and just stared hitting the Gladiator instead.
Other plants that drop Amber: White Tiger Lily, Red Bell Pepper, Deadly Ninja Fig, Sugar Khrystal.
