Is a Pact of the Chain Warlock’s quasit familiar really this effective as a spy?

One of my players has a Warlock with the Pact of the Chain. This PC has a quasit familiar. If we are applying the rules correctly…

Pact of the Chain

You learn the find familiar spell and can cast it as a ritual. The spell doesn’t count against your number of spells known. When you cast the spell, you can choose one of the normal forms for your familiar or one of the following special forms: imp, pseudodragon, quasit, or sprite. […]

Find Familiar

[…] While your familiar is within 100 feet of you, you can communicate with it telepathically. Additionally, as an action, you can see through your familiar’s eyes and hear what it hears until the start of your next turn, gaining the benefits of any special senses that the familiar has. During this time, you are deaf and blind with regard to your own senses. As an action, you can temporarily dismiss your familiar. […]

VARIANT: QUASIT FAMILIAR […] Familiar. The quasit can serve another creature as a familiar, forming a telepathic bond with its willing master. While the two are bonded, the master can sense what the quasit senses as long as they are within 1 mile of each other. While the quasit is within 10 feet of its master, the master shares the quasit’s Magic Resistance trait. At any time and for any reason, the quasit can end its service as a familiar, ending the telepathic bond.

… then he can communicate with it within 1 mile and see what it is seeing.

For example, in a mission where PCs have to peek at the enemy camp, he could just stay hidden and send the quasit exploring the camp. The quasit can turn invisible and polymorph into a centipede, so it can go anywhere (even inside a building), and the Warlock can see everything.

Now, is this correct? It would seem really overpowered to me.

If it’s correct, how can I limit this power in an acceptable way?

Question regarding Pact magic with multiclassing and a class specific bonus

I play a 6 bard/ 4 warlock multiclass. My character recently obtained a rhythm makers drum +3, giving a +3 bonus to my bard spells’ DC and rolls.

I am curious if I were to cast a spell I had taken on my warlock list (hold person) with a bard spell slot, would the bonus increase the DC? DnDB added the bonus to all my characters spells (I know that isn’t right) but thought it may be applicable if a spell is on both lists.

Thank you in advance.

Can a warlock use Pact of the Blade to restructure a magical pact weapon into a different form?

I don’t have the exact text, but I’m going to be running a Fey Warlock for an upcoming campaign. I remember this for Pact of the Blade at level 3: You may create your pact weapon in any form you wish, and you have proficiency with your weapon.

I don’t have the exact wording, but I know that you can make a magical weapon your pact weapon by spending some time with it, which can be done as part of a short rest.

My question is:

Let’s say the party finds a magical axe that let’s say its a +1 axe. If I make that weapon my pact weapon, then I summon it: can I choose what form it comes in? For instance, taking a magical axe, making it my pact weapon, and then reforming it as, a rapier instead. Or finding a magical weapon with an elemental-alignment, and restructuring it into a weapon better suited for the character?

The only time I could think that you would consider trying this with the Pact of the Blade is if you’re running a dex-based magical warrior, but it was an interesting idea that popped into my head. Does this work?

Can a 5th level Pact of the blade warlock, use his action to grapple, then attack twice with his pact weapon?

By RAW, when I use a grapple:

"Grappling

When you want to grab a creature or wrestle with it, you can use the Attack action…"

And the 5th level eldrich invocation:

"Thirsting Blade

Prerequisite: 5th level, Pact o f the Blade feature

You can attack with your pact weapon twice, instead of once, whenever you take the Attack action on your turn."

So, by RAW, can the warlock, with those requisites, use his action to grapple and then attack twice with his pact weapon?

Pact of the Blade and Weapon Bond with Magic Ammunition

While I was reading the book, I had a definite idea with reloading magic ammunition (Given that this ammunition is one). It’s not like from view of optimization, more like gamemechanic opportunity. I considered this from the point of the Pact of the Blade, but at the same time I was searching answers for Weapon Bond.
I know in advance that PotB allows you to use any magic weapon as a pact weapon, including ranged.

However, later on I came across Jeremy Crawford’s answer about using arrows with Weapon Bond. I wondered where I was wrong when I read the book, and I noticed one thing that caused misunderstand.

I considered only magic ammo. In Xanathar’s Guide and Dungeon Masters Guide when writing the type of magic item for ammunition, sourcebook directly write the type "Weapon (Arrow)". Perhaps:

Arrow of Slaying
Weapon (arrow), very rare

An arrow of slaying is a magic weapon meant to slay a particular kind of creature. Some are more focused than others; for example, there are both arrows of dragon slaying and arrows of blue dragon slaying. If a creature belonging to the type, race, or group associated with an arrow of slaying takes damage from the arrow, the creature must make a DC 17 Constitution saving throw, taking an extra 6d10 piercing damage on a failed save, or half as much extra damage on a successful one.
Once an arrow of slaying deals its extra damage to a creature, it becomes a nonmagical arrow.
Other types of magic ammunition of this kind exist, such as bolts of slaying meant for a crossbow, though arrows are most common.

Whereas common ammunition in PHB is classified as a just item (hence non-weapon) in the Adventure Gear list.

Is it right to make conclusion that in this case it can be considered as extension of Jeremy Crawford’s post, and Magic ammunition is legal for PotB and WB like pact/bond-weapon, but Non-magic ammunition is not legal for PotB and WB like pact/bond-weapon in RAW?

Pact of the Chain, Sprite Familiar. What does it mean that a “saving throw result is 5 or lower”?

I’ve been looking into the warlocks Pact of the Chain, which states that your allowed to pick from the normal familiars as well as a select few Warlock-Only familiars, including the Sprite.

When you cast the spell, you can choose one of the normal forms for your familiar or one of the following special forms: imp, pseudodragon, quasit, or sprite.

Then invocation Investment of the Chain Master states that:

If the familiar forces a creature to make a saving throw, it uses your spell save DC.

And the Sprite has a Shortbow attack that forces a creature to make a saving throw:

Shortbow. Ranged Weapon Attack: +6 to hit, range 40/160 ft., one target. Hit: 1 piercing damage, and the target must succeed on a DC 10 Constitution saving throw or become poisoned for 1 minute. If its saving throw result is 5 or lower, the poisoned target falls unconscious for the same duration, or until it takes damage or another creature takes an action to shake it awake.

From what I gather that means that the initial save for the poison should use the players save DC? So for a lvl 7 character with 20 charisma, that would be a save of 16?

Spell save DC = 8 + your proficiency bonus + your Spellcasting modifier

However the second part of the Shortbow attack states that:

If its saving throw result is 5 or lower, the poisoned target falls unconscious for the same duration

What does "saving throw result is 5 or lower" mean? Would that be the rolled number for the save + the save modifier?

saving throw result = save dice roll + save score modifier

Or would it be the resulting rest from removing the spell save DC from the rolled total?

saving throw result = Spell save DC – (save dice roll + save score modifier)

I haven’t seen the phrase "saving throw result" referring to a number before, usually it just refers to "did the creature roll over or under the spell save DC? Yes or No."

Can a 1st level spell from the aberrant dragonmark be casted by soley pact magic spell slots from a warlock?

For an adventure in D&D 5e starting at level 1 I have created a variant human warlock, with the feat aberrant dragonmark. I have chosen witch bolt as my first level spell from the feat.

In addition, choose a 1st-level spell from the sorcerer spell list. You learn that spell and can cast it through your mark.

My problem is from the that fact that the spell comes from the sorcerer spell list and makes me question, could I even be able to cast witch bolt using pact magic spell slots because it can also be found on the warlock spell list? If I can cast it, then my next question would be would be under the mark’s spell modifier (constitution) or or my warlock spell modifier (charisma)?

Do you get Hex Warrior’s Cha bonus with a two-handed Pact Weapon?

Hex Warrior says:

you can touch one weapon with which you are proficient and that lacks the two-handed quality. When you attack with that weapon you can use your Charisma for attack and damage rolls.

later the ability says:

This benefit extends to every weapon conjured with the Pact of Blades feature, no matter the type.

(emphasis mine)

Does this allow me to use my charisma with 2 handed weapons(provided it is my Pact Weapon and my Hex Warrior Blade)?

This question is not the same as Hex Blade Warrior & Pact of Blade. That one is asking how many weapons, I’m asking if type means 2 handed or something else(Slashing or Ranged for examples).

If you make a magic weapon your pact weapon, can you still summon other weapons?

The Pact of the Blade states:

You can use your action to create a pact weapon in your empty hand. You can choose the form that this melee weapon takes each time you create it. You are proficient with it while you wield it. This weapon counts as magical for the Purpose of overcoming Resistance and immunity to nonmagical attacks and damage.
[…]
You can transform one Magic Weapon into your pact weapon by performing a Special ritual while you hold the weapon. You perform the ritual over the course of 1 hour, which can be done during a Short Rest. You can then dismiss the weapon, shunting it into an extradimensional space, and it appears whenever you create your pact weapon thereafter. […]

Say I attune to a Flame Tongue (longsword), is that longsword now the only weapon I can summon through this feature? The Sage Advice makes it clear I cannot reform my Flame Tongue into a javelin, but could I just conjure a regular javelin that is not the Flame Tongue, as I could before I attuned to the magic weapon?

Does the Hexblade Warlock’s Hex Warrior feature apply to a magic weapon that is transformed into your Pact Weapon?

The Hexblade Warlock’s Hex Warrior feature states (emphasis mine):

[…] If you later gain the Pact of the Blade feature, this benefit extends to every pact weapon you conjure with that feature, no matter the weapon’s type.

Meanwhile, the Pact of the Blade Warlock feature states:

[…] You can transform one magic weapon into your pact weapon by performing a special ritual while you hold the weapon. You perform the ritual over the course of 1 hour, which can be done during a short rest. You can then dismiss the weapon, shunting it into an extradimensional space, and it appears whenever you create your pact weapon thereafter. […]

Does a magic weapon that you have transformed into your pact weapon benefit from Hex Warrior?
Does it count as a weapon you have conjured using Pact of the Blade?
Does the answer change if you shunt the weapon away and then make it appear afterwards?
