Arcane focus questions...

[samcifer]

So we've begun a new campaign (different dm for this one to anyone who's followed my previous threads) and this dm is saying that we'll be using the material components for spellcasting (we've ignored them in other campaigns).

Because of this, I want to use an arcane focus as it seems better and more versatile than a component pouch, but there's a few questions to understand how to use an AF best:

1. How/can it work with spells that consume the material component(s)? If so, do I lose the AF in the process?

2. Will it cover ALL components? are there any restrictions on types of components it can't replace?

3. Can I have more than one in case I lose one (say I carry 2 of them so I have a backup one just in case)?

4. Is there anything I should know about using them that I might be missing? (any special rules, etc.)

1. For spells that consume the material components and a price, usually in GP, you are required to have said components before casting the spell.

2. It will cover components that do not have a cost associated with them and that won't be consumed (e.g. Fireball uses guano and sulfur which the arcane focus can be substituted for, but Revivify requires a diamond worth x amount of GP which cannot be substituted for by the focus).

3. If you are able to find or purchase another (a component pouch works too) and carry it (Str permitting), there is no reason why you cannot. It needs to be an Arcane Focus for Wizard, Warlock, and Sorcerer spells; a holy symbol for Paladin and Cleric spells; a musical instrument for Bard spells.

A focus can substitute only materials components that both lack a cost and are not consumed.

If you want to cast a spell that requires a cristal worth 50 gp you can't use a focus in his place.

If you want to cast a spell that requires a hair of a hag and consumes it as part of the casting you can't use a focus in his place

If you want to cast a spell that requires 100 gp of diamond dus and consumes is as part of the casting you can't use a focus in his place.

That sayed an AF can sobstitute endlessly all other cases of material component required.

These answer both 1 and 2.
3. You can have as many non-magical arcane focus as you want (can afford).

4. If a spell requires a somatic component but not a material component and both of your hands are occupied even if one of those hands has a spell focus in it, you cannot cast the spell.

Unless you take the War Caster feat which allows you to ignore the somatic requirement for casting a spell and also has the added benefit of granting advantage for concentration saves.

1. Will not be consumed.
2. Can only cover for components that aren't consumed and don't have a price.
3. Technically yes, but not necessary unless you have a DM who makes frequent use of Thieves to steal your stuff.
4. Nope!

Besides Snare, what spells have M components don't have a listed cost but are consumed?

Protection from good evil is one

Is there a chance the DM will not be allowing focuses? Maybe I'm reading between the lines incorrectly.

It doesn't. War Caster allows you to provide the somatic component even when you're holding a weapon or a shield. You still need to provide the component to cast the spell, and it doesn't work if your hands are occupied with anything else.

Check with DM on how they handle Somatic Components and material components / focuses.

That line about being able to use the same hand to access material components / hold a focus and do the somatic gestures of a spell is one of the ongoing arguments on the forum.

To some, that means you can hold a focus the entire time you are casting a spell that uses the focus for the material component of the spell. To others, it means you do the somatic gestures and focus holding in sequence - the hand needing to be empty of even material components to form proper somatic gestures.

Not going to get into the arguments for or against either. Just find out the ruling this DM uses.
