farming for Hero Potion recipe

Hi,

Is the 'Kal Turok King Myrmex' in Dust Devil Canyon still the mob to farm for the Hero Potion recipe? I've been at it for hours, and no luck yet. Just want to make sure it's not broken, or I'm doing something wrong.

Thanks

mobs that drop the recipe is also listed here

Whoa!

So, all the mobs in the area drop the recipe, I didn't know that! I've been ignoring the others, of if I kill them, not looting

Big help! Thanks!
