Finally!!
I was stuck in the deepwood > ink > kobold loop when I decided to start adding 1 of each lightener every session until I hit a color that wasn't the dark dark ones.
When I hit Kobold Brown again I did 1 plum, 1 valfruit, 1 pineapple, and then another plum. All 4 proc'd and resulted in Marsh Green. From there, I did what someone else had suggested from Marsh Green. They did 2 berries and 1 apple to go to Ink Blue and then from Ink 1 pineapple to black. I combined those both in to one session so from Marsh I went 2 berries, 1 apple, 1 pineapple and got black. I guess 1 berry and 1 pineapple cancel each other out so I'm guessing just 1 berry and 1 apple from Marsh would've worked too.
Either way, so glad this is done with. I was losing my sanity. Thank you to everyone here who has contributed to the discussion and research of Chocotology.
