I propose a slight revamp to our herb system (And the collection thereof).
How this would largely work is to piggyback on top of the current mining system, like mineral veins and trees. Add another farmable product of different types of colourful herbs. Instead of having effects directly, so as to get rid of both the monotony and predictability and therefore boring nature of collecting greys/magentas/mandrakes/etc, make herb type rarity relevant. This would create an entire climate for herb trading and sales.
My idea is as follows:
-Coloured herbs throughout the lands in different forms of rarity.
-Local herbs can still be random but locatable, for instance leave an herb that converts to a low level bless in Everwild.
-The way these herbs can be used is to turn them into a reagent shop.
-Reagent shops have a unique relationship with each player.
-Collecting herbs for shops can reduce price, or offer more options.
Potential Herb Effects and Combining
-Herb Effect
-Duration
-Strength (Cast level)
Example:
Bob collects many herbs throughout the lands, he has rare herbs and lots of common herbs. He turns them all into his chemist/Reagent shop and in return that shopkeeper is willing to sell him 8 herbs of blessing and frenzy and 1 herb of slow, all with relatively decent durations.
Joe collects nothing and goes to the same chemist but can only buy basic low level herbs (That he and Bob begin the game with access to) at regular price. He does however come across a particularly rare herb but, being a cleric, he doesn't need its blessing so he sells it to Bob at a decent price who can then turn it in for better deals and effects on his own herbs.
Aside from creating certain inhibiting factors to stop this from spiraling to a herbcentric PK ideal, maybe only allow herb shops to produce inventory at certain intervals, and definitely keep them unique to each player. The upside of this idea is that, assuming we don't want to change what we already have, all current herb locations can be kept or simply replaced with a reagent equivalent. It would also make it incredibly easy to tone anything over or underpowered and make herb gathering more of a hobby than a downright necessity for PK. In my opinion herbs shouldn't be required to do well in PK, and as it is now the difference between a zero prep and full prep regarding ONLY consumables is insane.
