Spell Combat with a held charge vs casting a spell

My level 1 Magus has cast Shocking Grasp during the first round and missed his touch attack so is still holding the charge. On his second turn, can he use Spell Combat to attack with the spell in his offhand as well as taking a melee attack with his weapon?

Spellstrike (a level 2 feature) is not involved in this question at all. This is about whether Spell Combat can be used without actually casting the spell during the full round action if the spell is already being held in hand. Do I have to literally cast a spell during the full round action in order to qualify for spell combat or would holding a spell charge be enough?

I’ll need a full RAW answer to either confirm or overturn the ruling at the table (which I will not describe in order to leave the answer unaffected).

Note: I understand that at level 2, with spellstrike, I can deliver touch spells through my weapon. However, there is absolutely no interaction between that ability and this question.

Does Gentle Repose extend the time limit for casting Revivify?

The spell revivify returns a creature to life “that has died within the last minute.” [PHB 272]

The spell gentle repose “effectively extends the time limit on raising the target from the dead, since days spent under the influence of this spell don’t count against the time limit of spells such as raise dead.” [PHB 245]

My question is whether revivify is one of the “spells such as raise dead” for which gentle repose “effectively extends the time limit”, taking into account the fact that revivify is two spell levels below raise dead and its default “time limit” is not measured in days (it is in fact 1/1440th of a single day).

Casting Somatic Spells while handless (rules as intended) [duplicate]

This question hasn’t popped up in any of my games, whether as DM or player, but I thought of it while coming up with character concepts and wondered how it should be ruled.

If a caster does not have hands, can they perform the somatic components of their spells?

For example, if a player has the idea to have a caster born without arms who uses somatic components using their "ghost limbs" should they be able to since the restriction that they’re not wielding weapons or a shield isn’t being infringed?

Alternatively, if the above is true, does that mean players couldn’t disable an enemy caster they captured by Skywalker-ing their hands so they don’t have a free hand to cast the spell with?

The Player’s handbook describes somatic components as:

Spellcasting gestures might include a forceful gesticulation or an intricate set of gestures. If a spell requires a somatic component, the caster must have free use of at least one hand to perform these gestures.

But I don’t know how I’d interpret this.

I guess the main question is do somatic component rules emphasize having a (free) hand or do they emphasize not wielding an item/weapon? Are there any official rules for these edge cases or is there a way to interpret the rules on somatic components that answers these questions?

Should casting Confusion centered on yourself from Wild Magic Surge be trivial to end because it’s a concentration spell?

The entry for a roll of 13 or 14 on the Wild Magic Surge table is:

You cast confusion centered on yourself. (PHB, emphasis mine)

Confusion is a 4th level concentration spell. The rules for concentration state that:

If a spell must be maintained with concentration, that fact appears in its Duration entry, and the spell specifies how long you can concentrate on it. You can end concentration at any time (no action required). (PHB)

The intent of the entry on the Wild Magic table seems to be for everyone nearby, including the caster, to be hit by confusion, essentially a less-bad version of casting Fireball centered on yourself. However, since the table doesn’t specify anything special about concentrating on the spell, the caster needs to maintain concentration on it, and consequentially the spell should end if they stop concentrating on it.

RAW, is there any reason someone who rolls this result on the Wild Magic Surge table couldn’t immediately drop concentration and end the spell?

How would you rule on casting Scrying without material components?

Scrying has an M requirement of

a focus worth at least 1,000 gp, such as a crystal ball, a silver mirror, or a font filled with holy water.

While not explicit, this focus is presumably used to actually see and hear the target of the spell (e.g., this question).

Aberrant Mind Sorcerers can retrain one of their Psionic Spells for Scrying, and this feature allows them

to cast the spell using sorcery points, [requiring] no verbal or somatic components, and [requiring] no material components, unless they are consumed by the spell.

Since the focus is not consumed by Scrying, would you allow casting the spell this way? If so, how would you rule the scrying happens?

Can a spellcasting focus be used in the casting of a spell with no Material components

I have looked for any rules on this and cannot find any, and before you say "It doesn’t matter flavour however you like" I have a specific example.

In the alchemist subclass for the artificer class the 5th level feature alchemist Savant reads:

Whenever you cast a spell using your alchemist’s supplies as the spellcasting focus

does this mean that if the spell has no matterial componants that it cannot use this feature?

Psionic sorcery casting retrained Psionic spells

If an aberrant mind sorcerer casts a spell from the Psionic spells feature, they may use the Psionic sorcery too

When you cast any spell of 1st level or higher from your Psionic Spells feature, you can cast it by expending a spell slot as normal or by spending a number of sorcery points equal to the spell’s level. If you cast the spell using sorcery points, it requires no verbal or somatic components, and it requires no material components, unless they are consumed by the spell

However, the Psionic spells feature allows you too

You learn additional spells when you reach certain levels in this class, as shown on the Psionic Spells table. Each of these spells counts as a sorcerer spell for you, but it doesn’t count against the number of sorcerer spells you know. Whenever you gain a sorcerer level, you can replace one spell you gained from this feature with another spell of the same level. The new spell must be a divination or an enchantment spell from the sorcerer, warlock, or wizard spell list.

If you "retrain" one of the spells from calm emotions too Tongues could you then cast tongues for 3 sorcery points instead of a spell slot and without using verbal or material components?

Does casting spells thru mizzium armor allow for upcasting?

Mizzium Apparatus lets a caster cast a spell on their spell list for which they have a spell slot of the spells level to cast a spell that they don’t know, assuming a successful arcana check.. Per dmg pp141 "some magic items allow the user to cast a spell from the item. The spell is cast at the lowest possible spell level, doesn’t expend the users spell slots,and requires no components, unless the items description says otherwise".

This pretty clearly says that if i do not know the spell scorching ray, and i successfully use the Apparatus to cast it, it will cast as its native level.

Is this correct?
