We will be using a homebrewed approach to spell components, so consider the below ruling when looking at spell descriptions.
In 5th Edition D&D, some spells require material components. While many of these components are extremely cheap, or can be substituted for by an Arcane Focus (Tilly's Fairy Wand is one, for example), some components have a specific gold value listed next to them. In the rules as written, these components need to be actively bought and possessed by the user in order to cast the spell. Some of these components are EXPENSIVE, or bog down the game with excessive shopping or searching.
The Homebrewed Rule:
If it doesn't have a gold value associated with it, we will assume you have it, or have a substitute.
If it HAS a value, the impact of the spell will dictate what you need, fitting it into one of three categories.
- If the spell is a combat spell, used to cause a short term effect in combat to either hurt, heal, or control, treat the valued material as if you have it. Examples of spells like this would be Chromatic Orb's 50G Diamond, or Magic Mouth's 10G Jade Dust.
- If the spell is out of combat, but has an affect that isn't world bending or life changing, treat the valued material as if you have it. Examples of spells like this would be like Identify's 100G Pearl, Clairvoyance's 100G Focus, or Illusory Script's 10G Ink.
- Otherwise, if the spell is seriously impactful, such as raising the dead, mass teleportation, or direct answers from your DM or a Deity, you can spend the gold cost of the component to cast the spell, instead of having the physical material onhand. Examples of spells like this would be Revivify's 300G Diamond, Awaken's 1000G Agate, or Plane Shift's 250G Rod.
When the spell fits into the third category above, you only need to spend the money each casting if the item would be consumed when the spell is cast (300G for every Revivify, for example). Items that merely need to be present, will be "bought" when you first cast the spell, and then forever in your possession from then on out. This means that the first time a druid casts Plane Shift, they'll need to be able to fork over 250G to have retroactively bought the Rod the spell requires, and then on out will have it for future casts.
The nature of these rules will likely change, and if you have questions about a specific spell this is the place to ask it. But for now, this is what we're going to go with.
Spells with material costs that have been established in each tier:
- Chromatic orb
- Magic Mouth
- Illusory Script
- Plane Shift
