Taking your hand off the weapon should not require any action expenditure - you are just letting go of it, same as if you dropped it.
You can then use your free object interaction to restore your grip after casting.
The PHB Errata says:
Two-Handed (p. 147). This property
is relevant only when you attack with the
weapon, not when you simply hold it.
It looks like your real question is can a spellcaster use Eschew Materials to create undead without having a corpse handy?
The answer to that question is no.
Components V, S, M (an onyx gem worth at least 25 gp per Hit Die of the undead)
Targets one or more corpses touched
Components V, S, M (a clay pot ...
An undead eyeball
Acquiring an undead eyeball itself seems relatively trivial for the unethical necromancer; simply kill someone, animate them as a zombie using Animate Dead, and then pluck an eyeball from your new zombie friend.
I have interpreted this requirement to mean the eyeball of an undead creature, not specifically an eyeball that is an animate ...
My insurance company? New Ork Life, why do you ask?
There are a number of Q&A's on this site that ask "What good is gold in 5th edition?" since the Wealth By Level (WBL) framework is no more. Our first group discovered that as we went up in levels, and needed our spellcasters to cast higher level spells, gold was required to buy spell components for ...
There are two aspects to this question:
Why have material components that are free or inexpensive?
Why make them all different?
Why have Inexpensive material components
Most of the time, the presence of a free material component will just mean the caster needs to interact with an arcane focus or component pouch. They will need a hand free to do this.
The Sorcerer is indeed Silenced by their own spell.
Nothing in the spell description excludes the Sorcerer from the spell. The only way to get around this is if the Sorcerer also has the Subtle Spell meta-magic skill selected so that they can remove the Verbal component.
Nothing about casting a spell makes you immune to it's effects unless it's stated in ...
No, Major Creation works like Minor Creation, which states:
Attempting to use any created object as a material component causes the spell to fail.
You can create your diamond dust, but that dust cannot be used as material component for spells.
You could probably attempt to sell it, make some money, and then use it to buy non-magical diamond dust. But be ...
The rule on spellcasting does not say that you need a component, but:
Each spell's description indicates whether it requires verbal(V), somatic(S), or material(M) components. (PHB 203)
So technically there could be a spell that does not list any components. Subtle spell overwrites even the above rule, which it can do as a class ability is more specific ...
No, you can't counterspell spells with no components
Subtle spell is meant to protect against counterspelling.
Subtle Spell is meant to protect a spell w/o material components from counterspell, since you can't see the casting.
(from a tweet from Jeremy Crawford)
As an action while it is temporarily dismissed, you can cause it to reappear in any unoccupied space within 30 feet of you.
This is not casting the spell and so any restriction on Components you can currently use is not relevant.
All this says is that causing your familiar to reappear take your action for the turn in which you do it. As ...
The components are only consumed when specified.
Player's Handbook p. 203 (or here in the basic rules):
Casting some spells requires particular objects, specified in
parentheses in the component entry. A character can use a component
pouch or a spellcasting focus in place of the components specified for
a spell. But if a cost is indicated for a ...
The rules for spellcasting spell this out clearly:
A spellcaster must have a hand free to access a spell’s material components—or to hold a spellcasting focus—but it can be the same hand that he or she uses to perform somatic components. (Source: 5e System Reference document)
First off, I somewhat disagree with Jeremy Crawford's tweet. Since no cost or amount of holy water is listed, I (as DM) would not expect you have to expend an entire flask -- I would expect it to be something like what you'd see in a modern Catholic church, where you only use enough holy water to wet the fingertips (or a pinch of iron and silver); a ...
Value is absolute
The rules of D&D seem to assume that value is absolute, not relative. That is to say, things have the value that they have (especially precious items like gems and jewels, artwork, precious metals, etc.) and that's unrelated to how much you might be able to actually buy and sell them for in your present circumstances. A 100gp pearl is ...
Ask your DM
Unfortunately, there really isn't any RAW for how to handle damaged tongues or even being mute. For the most part, and except for an optional damage rule from the DMG, there really aren't RAW mechanics for PCs losing body parts.
And all of this is dependent on how a DM defines the disability.
If they rule that the character is mute, then they ...
This was entirely appropriate. You have nothing to complain about.
Do you think spellcasters should spend their own hard earned gold to help you out? Spellcasters are generally the only ones that significantly need gold in AL play. Having people set aside gold if they think they'll need Revivify is a good suggestion on the cleric's part. I'm sure others ...
Spell is not cast, no resources lost
This is covered under Casting a Spell rules in Chapter 11 of the PHB(emphasis mine):
A spell's components are the physical requirements you must meet in order to cast it. Each spell's description indicates whether it requires verbal (V), somatic (S), or material (M) components. If you can't provide one or more of a ...
"Penny for Your Thoughts"
Although the writers were almost certainly referring to a common copper coin for their joke, there's no indication this was meant as an actual "cost". The 5e authors consistently use the term "worth" or "value" whenever an actual material component cost is indicated, and they express that cost in gp (I've yet to find one costing ...
The answer is on page 79 of the Basic Rules:
Casting some spells requires particular objects, specified in parentheses in the component entry. A character can use a component pouch or a spellcasting focus (found in chapter 5) in place of the components specified for a spell. But if a cost is indicated for a component, a character must ...
Ulmus Glabra aka Ulmus Glabra Montana is also known as Scotch Elm, Wychwood, Wych Elm, and Witch Hazel. (Witch Hazel is a different shrub in the US). It was used to make divining rods and had other reputed magical properties.
One of the things you lose by just treating components as "junk" and abstracting them away is that it's one of the remaining sources ...
A cyst, in the biological sense, is a "closed sac, having a distinct membrane and division compared with the nearby tissue". You would expect to see some sort of membranous, organic sac full of mud, dug into or emerging from the ground.
This possible method of using the clone spell is almost certainly a reference to the depiction of the creation of Saruman'...
No canonical list
There is a very obscure list, but it was printed long after the concept of forks for plane shift first originated, so for a long time there was no list. And that list was published in Dragon magazine and never again referenced, making it largely unknown; the overwhelming majority of tables will be unaware of it. In such a case, you’d have ...
...the particular combination of sounds, with specific pitch and resonance, sets the threads of magic in motion.
If you can argue that this is ALL that is needed to cast a purely verbal spell, then anyone or anything with a mouth can cast it.
Let's get more basic: suppose you don't have spell slots left to cast ...
There are two reasons I'm aware of.
The first is for the rare situation of when a Spellcaster is deprived of focus and component pouch. Having specific components for each spell allows some of them to be gathered from the environment.
As an example, at the beginning of the published adventure Out of the Abyss, the characters start the adventure ...
It’s not just cheap components that are reusable. For example, the identify spell does not state that the 100 gp pearl is consumed:
Components: V, S, M (a pearl worth at least 100 gp and an owl feather)
Based on that spell, along with Colin D’s answer, components are only consumed if it’s explicitly stated.
First of all, I'm curious as to why the non-gp materials are included
in the spell description at all if they are never going to be
considered. Yes, it adds flavor, but since the material components are
effectively ignored in play, the flavor is lost.
They're only ignored if you have a spell component pouch or the feat Eschew Materials, and the ...
Yes, you can cast spells with a Material (M) component without issue.
Your Holy Symbol takes care of it.
This is one of the more difficult things to look up in the current 5e rules. It starts on page 58, under Cleric spellcasting:
You can use a holy symbol (found in chapter 5) as a spellcasting focus for your cleric spells.
In the equipment section, ...
Yes, you can cast prepared spells which require only Verbal and/or Somatic components when deprived of your focus. (As long as you can produce the Verbal and Somatic components, that is.)
The focus only functions to replace (subject to the limitations you mentioned) such Material components as are required. It, like a component pouch, is not implicated when ...
