If it is latex you require, you would do well to search just outside the Blue Badger Gate or the Yellow Serpent Gate.
Seek out the mature trees that stand in those areas, and then put your hatchet to use. I wish you well.
How goes the gathering effort? Lest you forget, latex can be had just outside the Blue Badger Gate and the Yellow Serpent Gate.
Ah, yes. Precisely ten pots of latex, just as I instructed. You have done well.
