You might not even need Subtle Metamagic
The Knock spell states that:
[...] When you cast the spell, a loud knock, audible from as far away as 300 feet, emanates from the target object [...]
As long as you are outside the Silence when you cast the spell, but the object itself is inside, the Silence spell will absorb the loud noise.
Knock has a 60ft ...
Step 1: make a sorceror.
Okay, now you've got a sorceror. One-half of the build is complete.
Step 2: use a sword.
Anyone can use any weapon. Sorcerors aren't proficient with swords, but that just means that you don't add your proficiency bonus to attacks made with swords. You can still attack with them, they still do the same damage when they hit. You're at ...
Dispel magic ends the effect on only one target
1. This is a confusing area. RAW would appear to suggest that dispel magic should end the effect on both targets:
The rules for twinned spells state:
When you cast a spell that targets only one creature and doesn’t have a range of self, you can spend a number of sorcery points equal to the spell’s level to ...
No, it doesn't completely bypass immunity
When a feature is designed to ignore both immunity and resistance to a damage type, rather than "reduce/step down" one level of protection, it is quite explicit in this. One other class feature does this - the School of Evocation wizard's Overchannel feature:
[...] Each time you use this feature again ...
Each description specifies targeting a second creature.
Each feature description is specific to state that we may “target a second creature”. Twinned spell says:
target a second creature in range with the same spell.
Split enchantment says:
you can have it target a second creature.
The first three ordinal numbers in English are first, second, and third; ...
Yes, a Dragonborn sorcerer only has 4 skill proficiencies: 2 from sorcerer and 2 from their background.
That said, there are only 3 classes that grant more than 2 skill proficiencies: Bard and Ranger gain 3, and Rogues get to choose 4. Having only 4 proficiencies is therefore quite common, unless your Race grants additional proficiencies, e.g. Elves (...
It feels like nothing, because they are not aware of it
"Levels" in every version of D&D are a metagame concept, they're an abstraction of the characters abilities, strengths and flaws. Your Sorcerer does not wake up one day with a new level and is suddenly capable of casting a new spell, it's something that has been developing over time.
The sorcerer, as we know it, dates back to D&D 3e, which was the first under Wizards of the Coast. To date, to my knowledge, they have never gone into a lot of detail about this kind of thing.
In 3e, even the whole concept of sorcery coming from a bloodline wasn’t really a part of the original description.
Some sorcerers claim that the blood of ...
Extended Spell only extends the duration once by doubling it.
A caster can't use Extended Spell multiple times on the same casting, and the feature doesn't accommodate using multiple sorcery points at once.
This is addressed directly in the Sage Advice Compendium
At the bottom of page 5 of version 2.4 of the SAC, it says:
Metamagic rules state you can’...
Sorcery points are replenished to a maximum.
You may convert your unused spell slots into sorcery points before taking a long rest, however they cannot exceed your maximum.
Upon waking all sorcery points will be replenished, to your maximum and no more.
You can never have more sorcery points than shown on the table for
your level. You regain all spent ...
This does not use spell slots so you cannot convert anything
The Infernal Legacy feature states:
You know the thaumaturgy cantrip. When you reach 3rd level, you can cast the hellish rebuke spell as a 2nd-level spell once with this trait and regain the ability to do so when you finish a long rest. When you reach 5th level, you can cast the darkness spell ...
There are some Metamagic options that are more situational, and there might be some abuse you could do. There's two things I see:
In many campaigns and situations, this ability is pretty much useless. Somatic and verbal components hardly ever matter to your character, unless it's a flavor thing or your character likes lugging around heavy ...
With Subtle Spell, you cast
without any somatic or verbal components
Thus this casting of the spell is no longer
a spell that includes a verbal component
Properties of a spell can change for given castings, the main example being its level, depending on the slot. Thus the spell can be cast.
This will also achieve the desired effect, as ...
It provides more flexibility than intended to classes, which is more forgiving to unexperienced players, and powerful for experienced ones.
If your kid isn't trying to optimize the character because, as you say, he's a kid and lacks experience, this is a fun homebrew rule. If he takes metamagic options he dislikes, he can fix that mistake. It makes the ...
Yes, Elemental Affinity will only affect fire spells (given your choice of gold ancestry)
The Draconic Bloodline feature, Elemental Affinity, says:
Starting at 6th level, when you cast a spell that deals damage of the type associated with your draconic ancestry, you can add your Charisma modifier to one damage roll of that spell.
Where it says "...
Favored by the Gods states:
If you fail a saving throw or miss with an attack roll, you can roll 2d4 and add it to the total, possibly changing the outcome.
If it is casting a spell of 4th level or higher, make an ability check using your spellcasting ability
Since Counterspell requires an ability check, not a saving throw or attack ...
RAW: Yes, Crown of Madness can be Twinned
The text for Twinned Spell:
When you cast a spell that targets only one creature and doesn’t have a range of self, you can spend a number of sorcery points equal to the spell’s level to target a second creature in range with the same spell (1 sorcery point if the spell is a cantrip).
And the ...
This sounds like a mix of example of multi-hit spells and some potential future proofing because subclasses like the Loremaster Wizard from UA may eventually exist officially which allow you to change the elemental type of damage cantrips.
Taken from Spell Secrets
When you cast a spell with a spell slot and the spell deals acid, cold, fire, ...
The maximum damage on a missed attack is zero.
The effect still applies, but in the case of a missed attack roll, the maximum damage you can deal is zero damage.1
The 33-34 Wild Magic Surge effect applies on the
next damaging spell you cast.
Notably, it is not on the next damage spell that does damage, only on the next damaging spell you cast. So if you ...
The Favoured By The Gods feature states:
Starting at 1st level, divine power guards your destiny. If you fail a saving throw or miss with an attack roll, you can roll 2d4 and add it to the total, possibly changing the outcome.
If it is Casting a Spell of 4th Level or higher, make an ability check using your Spellcasting Ability.
It is not possible without first transcribing it
Unfortunately, the Ritual Caster feat (PHB, p. 169) has only two ways to put spells in the book.
First is when you select the feat:
When you choose this feat, you acquire a ritual book holding two 1st-level spells of your choice.
So those first two spells just automatically show up in the book. The next ...
Forever, as written
The ability as written doesn't have a defined duration, only an end condition - that being that you can use a bonus action to end it. It's not a concentration-based effect, so you don't have to maintain concentration on the ability to keep it going - so you can cast concentration spells, take damage, and even sleep, without the effect ...
Only if the spell appears on the Wizard spell list
The rule on copying spells into a wizard's spellbook in the "Your Spellbook" sidebar says (Player's Handbook p. 114; emphasis added):
When you find a wizard spell of 1st level or higher, you can add it to your spell book if it is of a spell level you can prepare and if you can spare the time to ...
Yes, Metamagic may be applied to spells that are cast using a class feature instead of spell slots.
The Metamagic feature says a metamagic option may be applied when the sorcerer casts a spell:
You can use only one Metamagic option on a spell when you cast it, unless otherwise noted.
That is the only criteria: the Sorcerer must cast the spell.
I believe that in both cases, the "you must use the new roll" should be interpreted only within the context of the effect itself. That is to say, the intent is that the Flames of Phlegethos effect can only reroll a given die once; you don't get to keep rerolling 1s until you come up with something that isn't a 1. But then once all that rerolling is ...
Darkvision effectively makes dim light bright, and darkness dim light; the total range here is 120 feet.
The section on "Darkvision" states:
A monster with darkvision can see in the dark within a specific radius. The monster can see in dim light within the radius as if it were bright light, and in darkness as if it were dim light. The monster can't ...
Until you use a bonus action to end it.
This class feature is written like a perpetual umbrella:
If it is raining, you can use an action to cause the rain to stop falling in a 20-foot-radius sphere centered on you. You can end this effect as a bonus action.
That’s it. That’s all there is to it. It doesn’t mention concentration or even being conscious. It ...
The Metamagic option Empowered Spell says it may be used "when you roll damage for a spell."
When you rolled all three of the dice, you were rolling damage for the spell. Your decision of how many and which dice to re-roll (one, or up to your Cha limit, two; a d8 or the d6) needs to be made at that time (after you see the results of the initial ...
Haste is a Red Herring; you're limited by casting a spell as a bonus action
In the PHB page 202 under Bonus Action, it states:
You can't cast another spell during the same turn, except for a cantrip with a casting time of 1 action.
Given that, we can work with how we can cast spells.
If, on your turn, you quickened cast Haste, that leaves you with your ...
