Swim told me that the PurplePink variety has more magic concentration, and that the PurplePink isnt a variety in fact, but a different way of preparing the rootbark...
Swim has also told me that the magic of the plant is mostly in the middle layer of the RB, so aparently the PurplePink is the same material, but its like a filet, with only the good part of it...
So if the material u got looks like the same as normal RB, then its likelly that you`ve got the normal material as they should look different visually.
