Reagent Costs Follow Your Class
Mounts and trainer ranks are paid once. Reagents are paid again every week you play, and the bill is split unevenly: some classes hand coin to a vendor before every raid night, and some never open that shelf at all.
Which classes actually pay for reagents
A reagent is a vendor item a spell consumes when it is cast. That makes it a different kind of expense from gear or training: it does not end, it scales with how often you play, and it is decided by the class you rolled rather than by how you play it. Paladins buy symbols for their blessings, mages buy runes for teleports and portals, druids carry seeds for battlefield resurrection, shamans carry ankhs, priests buy candles for the group versions of their stamina and spirit buffs.
Warlocks sit oddly in this list. Their currency is soul shards, which cost nothing at a counter and everything in storage, so the bill arrives as bag slots held permanently in reserve rather than as coin. Hunters and rogues pay an equivalent amount in ammunition and poisons, which are not reagents by the game's definition but behave exactly like them in a weekly budget. Warriors come closest to paying nothing of this kind at all.
The practical effect is that 2 players at the same level, with the same gold, have different disposable income. A paladin and a warrior can clear the same dungeon and walk away with the same drops, and only one of them restocks before the next run.
Group size is what moves the bill
Reagent spending does not rise with your level so much as with the number of people standing next to you. Single-target blessings and single-target stamina buffs are cheap and short. The group and raid versions are the ones that eat a stack: they cover a party or a class at once, they are the versions a raid leader asks for by name, and each cast burns another unit of the vendor item. A solo levelling paladin barely notices the shelf. A raiding one visits it before every reset.
That puts reagents in the same weekly column as flasks, food and potions, but they behave differently from the items covered in what a raid night consumes. Consumables are bought from other players at whatever the listings ask. Reagents are bought from a vendor at a fixed counter price, so they are predictable, they do not spike when a guild starts progression, and they cannot be farmed to avoid buying.
Casters carry both bills at once. The shelf that refills a mana bar is player-supplied and moves with supply, which is the subject of water and food bought between pulls, while the reagent shelf next to it does not move at all. Budget them separately or the stable half gets blamed for the volatile half's prices.
Portals, summons and resurrection sold to other players
Two of these expenses are also income. A mage pays for the rune that opens a portal and can charge the group more than the rune cost, which turns a reagent into a margin. A warlock pays nothing at a vendor and still sells the same service, which is why charging gold for a summon is close to pure profit while a portal is a trade with a cost of goods. Both are selling the same thing: somebody else's travel time, priced against a flight path.
Resurrection reagents work the other way. A druid's seeds and a shaman's ankhs are spent at the worst moment of the evening, when a pull has already gone wrong, and nobody is paying for them. They are insurance bought in advance and consumed by failure. The same wipe produces the other 2 bills a raid night can generate: repair on worn gear, and the charge covered in what a spirit healer takes if the run back is not worth the time.
Read together, a wipe costs a group more than it costs any individual in it, and the share is uneven again. The tank pays in durability, the druid pays in seeds, the warrior pays in neither. That is also the honest case for keeping reagent stock deep: running out mid-raid converts a cheap vendor item into a wasted evening for 9 other people.
What is not confirmed for Forever
Everything above describes how reagents have worked in Classic-era WoW. We have not seen a Forever-specific statement on which spells keep a reagent requirement, which vendors stock them, or whether any of the new recipes replace a vendor item with a crafted one. Forever changed professions more than any previous version, so the possibility that part of this shelf moves from an NPC counter to the auction house is real, and we are not going to guess at it before there is something to read.
We also do not know whether the Legacy system touches reagent consumption, and we have not seen a perk described in those terms. If one exists, it would change the class balance of this bill rather than its size, which is a different question from the yield perks discussed in points spent on gathering output. Until that is confirmed, plan around the version of the rules that is already published.
What is safe to assume is the shape, not the amounts. Reagents are a recurring, class-bound, vendor-priced outflow that sits underneath the one-time spending listed in training, repairs and respec charges. Treat it as a standing weekly line for the classes that pay it, and as a reason to check before rolling an alt you intend to raid on.
Questions
Which classes pay the most in reagents?
The ones with group-wide buffs and utility casts: paladins with blessings, mages with portals and teleports, priests with the group stamina and spirit buffs, and druids and shamans with resurrection items. Warriors and rogues pay little or nothing on the reagent shelf itself, though rogues and hunters carry an equivalent weekly cost in poisons and ammunition.
Are reagents bought from vendors or from other players?
From vendors, at a counter price that does not move with demand. That is the main difference between reagents and consumables like food, water and flasks, which are made by players and priced by the listings. It also means reagents cannot be farmed out of the budget: you can only reduce the bill by casting the cheaper single-target versions instead of the group ones.
Does a warlock really pay nothing for summons?
Nothing at a vendor. Soul shards are collected in combat rather than bought, so the cost is storage and the time spent refilling them, not coin. That is why summoning can be sold at a wider margin than a mage portal, where the rune has a real purchase price behind it.
Should an alt be chosen around the reagent bill?
Not on its own, but it belongs in the arithmetic. A class with a standing weekly reagent cost needs a slightly larger working balance before it starts raiding than one without, on top of the usual startup spending every new character faces. For a character rolled purely to support the main, the difference is small; for a second raider, it is a real line.
