Does Wealth By Level allow for "free" potions?

Question

The principle behind the wealth by level table in the DMG is to summarize the amount of magical gear that a character will have access to at each level.

It's clear that the potions, scrolls and other consumables that are available should be included in the wealth count. Anything that has been consumed can't benefit the character and thus isn't counted as wealth.

Does this mean that characters are expected to use consumables regularly? What is the opportunity cost of using those consumables? Do they become free over the long term?

For example, a party that uses a Potion of Heroism for every character in every fight they can up to level 20 will get much more treasure over 20 levels than a party that saves their potions for the fights they need it.

Answer 1

The suggestion I'd make on handling parties that use an abnormal amount of consumables is the one of staying true to what little rules we do have: hand out an appropriate amount of treasure, and let the players decide how to apply it. If they spend lots of gold on consumables, they end up with fewer permanent magic items. If they spend little... well, they'll have more shinies. In other words, I do not suggest enforcing WBL on characters that already exist - and there is no rules premise for doing so, as far as I can tell. What you should be focusing on is handing out the correct amount of treasure.

Starwed's answer contains information on how much gold the game assumes characters will collect throughout their adventuring career.

Answer 2

“Wealth” is defined as the total value of the assets you have. A potion you used three levels ago is not an asset; its current value to you is zero. A potion in your backpack, on the other hand, has value: you can still use it.

However, consumables, by definition, have fleeting value. Once used, they no longer have value, and a character wouldn’t consider them a part of his or her wealth. In 3.5, it’s expected that the players’ wealth will fluctuate up and down, hopefully roughly around the WBL values for their level. So a potion that gets used results in a loss of wealth, but then perhaps the treasure at the end results in more wealth (and perhaps more potions) until that wealth is used, and so on.

Answer 3

Yes, the consumables are included into WBL calculation and you're expected to 'pay' for them at the character creation.

No, that does not mean that anybody is expected to use the consumables. You may not even have them, despite that the relative cost of low-level potions and scrolls is negligible at higher levels. In a certain sense they are free - when we're talking at 760k gp wealth for level 20, 50 gp for a potion is essentially free.

The opportunity cost, I believe, cannot be calculated in general, since the alternatives to using a consumable a highly dependent on circumstances.

For the purpose of estimating treasure given out during play, WBL should be calculated as the sum of the treasure given to players, not the sum of the treasure they still have on hand. Thus it will include the consumables they bought and consequently spent, and therefore the group which spends a potion of Heroism each encounter, as per your example, has exactly the same WBL as the group which conserves their consumables (but probably less cash or permanent magic items).

While the following DMG quote (treasure, p51)

Table 3–5: Treasure has been created so that if PCs face enough encounters of their own level to gain a level, they will have also gained enough treasure to keep them apace with the wealth-by-level information found in Table 5–1: Character Wealth by Level (page 135). Just as gaining a level requires between thirteen and fourteen encounters of a party’s level, so too fourteen average rolls on the table at the party’s level will get them the treasure they need to gain the appropriate amount for the next highest level, assuming that the PCs expend some resources such as potions and scrolls during those encounters.

seems to disregard some consumables in WBL calculations, I personally find this inherently incorrect, as it allows for certain abuse.

For those willing to give the players some spending money for consumables, I suggest that the difference between WBL by table 5-1 and WBL by average encounter treasure (as noted by @Ernir, this difference is noticeable) was used for this purpose.

(This is actually suggested by DMG itself, p54)

As you can see, rewards using these tables generate more wealth than indicated. We assume characters use up that additional money on expenses such as being raised from the dead, potions, scrolls, ammunition, food, and so forth.
