Absolutely Astral, I agree that from a personal use perspective, Herbalism is great.
This is what makes it a complex issue, because those smiths, tailors, and art-crafters who are heavily invested in their trade still need consumables, and those consumables have to come from somewhere.
They also won’t pay too much for them, because you’re competing against (in most cases) wand usage and potions you can either get with the Brew Potion feat or from NPCs and monsters.
Healing Draught is a great example of this, because the one bonus the herbalist version has is that it works in anti-magic areas. Very niche, rarely matters.
The materials for it? Easy and cheap
DC? Low
Points cost? 54 (so 27 with mastery) for ten potions.
Thing is, there’s a cost ceiling of about 400gp because you can buy CCW potions from NPCs for that much.
The average smith, tailor, or carpenter can walk into a settlement and get paid 5000gp for dumping 50 crafting points into a trade project.
If a herbalist makes twenty Healing Draughts, they can sell them to someone for about 250-300gp each, so a similar income point, through a store, except that there’s taxes and minor material costs.
So this is okay, assuming folk want to buy them.
And each one will heal about 60-ish HP.
A Heal potion, by comparison, heals 165hp I believe?
So let’s say it heals three times what a Healing Draught does, and folks will drink them like (boozy) water in tough combat.
So you multiply the cost of a Healing Draught by 6 or so (three Healing Draughts, but double again for action economy saving), getting you into the 1500-1800 price range, maybe 2,000gp.
If you go over this, other Herbalists will undercut you in most circumstances (and burn out) because some folk want to help others… and this is their choice.
The issue with these isn’t even the points cost (around 950ish points if you do it all yourself with herbalism mastery rolls and 1 point in art), it’s the difficulty in getting King’s Crown.
Thing is, for 950ish points you make 200,000gp, and yes, that’s about double what a smith makes dumping points into crafts for folks… although material costs and taxes mean that you’re putting in a lot more work for that income. Heal potions are okay, if you can use Druid Sickles to get King’s Crown or have some other workaround to get something that spawns once every twenty minutes in lots of 1-5, in rare locations that players are not supposed to sit on and harvest for days.
Freedom of Movement potions, by comparison, sell for about 500-600gp, cost the same in crafting points, with easier to get materials. So you get maybe 60,000gp, for what a smith can get 95,000gp, AND you have materials and taxes coming out of that.
A fairer price for FoM and Deathward potions would be around 1,000gp each, and about 600gp each for NEP (points cost for those is less, but materials cost, etc.) .
Good luck selling at those prices though.
Why?
Because you are competing directly against wands for those potions for most characters.
So your choice is to price for your effort and not get sales, or price competitively to get sales and watch that effort not really reward you.
And with Heal potions, the functional rarity of King’s Crown really means that they should be selling for more than they are (although if they are too much more expensive we’re incentivising folk to break server rules, which is a bad idea), but the market, again, won’t support such price increases.
