After completing Niesa's Draught (part 3) and receiving ten of the lovely potions, I of course wanted to have more made.
And then I realized that only an alchemist can even loot the required components to make the potion. That doesn't really make much sense to me honestly, anyone should be able to loot those components if not actually produce the potion.
If the components weren't annoying to get, I wouldn't complain because an alchemist would have no problems gathering them and making them for others. But because they are so annoying to get (ravager hearts in particular), I highly doubt those with the form scribed would make more potions for anyone but themselves. This would bar any dragon or biped who hasn't leveled alchemist yet from getting more of Niesa's Draught unless they find an alchemist willing to go through the annoyance of hunting those comps.
What I suggest is allowing those with Niesa's Draught (part 3) completed to loot the components so even if they aren't an alchemist, they can trade the components to someone who is if they want more potions made.
