Is there a class ability, spell or other, that lets you share spells with your familiar?


I have a Wizard/Warlock with pact of the chain feature, who I have themed off He-Man. I love the idea of using Tenser’s Transformation to buff both he and his familiar up for combat. However, it has a range of self, which seems to really limit my options.

Anyone have a work around? I am willing to change my class or multi class as needed. (We stick to using the hardcover books, and not UA or 3rd party stuff)

How to devise cryptographic system with sharing ability

I am writing a application. For my application the data of the users should be encrypted in the database. The users should also be able to share data with other users. To that end I want to you RSA encryption.

My intended implementation is as follows: The public key of the user is stored in the database. Data that is to be shared with another user is encrypted with that users public key and stored in the database. Now, here are two problems I am facing with this approach:

1.) I want the public/private key pair to be derived from the user password so as to not have it stored anywhere unsafely on disk. Whenever the user logs into the application, the private key is derived and user data can be de-/encrypted. My question is, how can I derive an RSA key pair from the password?

2.) If the user resets their password, no previously encrypted data can be decrypted anymore, as that would require the user’s old password in order to derive the private key. As far as I know, one solution to this problem is to encrypt/decrypt using a randomly generated data encryption key that doesn’t ever change, and to then encrypt that key using a password based key. But then how can a user share encrypted data with other users? For that the user would have to also share their password based key in order to grant access to the public data encryption key, which obviously is against the whole point of encryption.

So, how do I go about reconciling and solving both of these issues?

Scribing a scroll with an enhanced Spell-Like Ability

Following up on my previous question regarding the scribing of Spell-Like Abilities, I’d like to know how feats that affect the SLA, such as Intensified SLA, Quicken SLA, etc., affect the scribing. Unlike actual Metamagic feats, these don’t affect the "spell level" of the SLA, they’re simply usable 3 times per day.

For instance, would a quickened 1st level SLA count as 1st or 5th level for the purposes of scribing (and therefore, the gold cost)?

How does the Dimensional Loop’s Fold Space ability interact with areas of effect?

The magic item Dimensional Loop (Acquisitions Incorporated, pg. 220) has an ability called Fold Space which says:

Choose a space you can see within 60 feet of you (no action required). You treat that space as if it were within 5 feet of you until the end of your turn. This allows you to move immediately to that space without provoking opportunity attacks, or to interact with objects or creatures in that space as though they were next to you (including allowing you to make melee attacks into that space).

Suppose Jim Darkmagic is having a dual with another mage, and they are 50 feet apart. The mage uses its action to hold a fireball spell until he sees Jim casting a spell. On Jim’s turn, he uses the Fold Space ability of his Dimensional Loop and chooses the space the mage is occupying. Until the end of Jim’s turn, the mage’s space is treated as if it were within 5 feet of Jim. Next Jim starts casting inflict wounds on the mage. Seeing this, the mage uses his reaction to cast fireball centered directly on Jim.

Is the mage considered to be within the area of effect of his own fireball?

Similarly, does Jim need to be wary of casting his own fireball on the mage until next turn?

Scribing a scroll with a Spell-Like Ability

Magic Items

A spell prerequisite may be provided by a character who has prepared the spell (or who knows the spell, in the case of a sorcerer or bard), or through the use of a spell completion or spell trigger magic item or a spell-like ability that produces the desired spell effect.

If I have a Wizard with Scribe Scroll who is able to cast a spell not on the Wizard’s spell list as a Spell-like Ability, would he be able to scribe a scroll of that spell?

Does the undead controlled by the Oathbreaker paladin’s Control Undead ability get advantage/disadvantage on the saving throw?

I have two questions about my Oathbreaker paladin’s relationship to the undead.

When I use my Control Undead Channel Divinity option, I can take control of an undead. My question is “Does the turn undead resistance offer advantage on the saving throw?”

I tried to control a ghast one time. It had turn undead resistance so my DM said it had advantage on the saving throw because of that.
Is that how it works?

Directly related to the above is: when I use control undead again on an undead that I already control, does it have to make the saving throw again, or do I have an advantage somehow because I already control him?

Do true polymorphed gold dragons retain their ability to cast spells?

I recently rewatched Mr. Rhexx’s video on gold dragons and he mentioned that they love to practice magic. He also mentioned that all dragons can innately cast spells but gold dragons choose to further their magic prowess. Now true polymorph states that whilst morphed you can’t cast spells unless your new form is capable of such. Now spell casting actually isn’t present in the 5e gold dragon stat block so my question is if a mage was true polymorphed into a gold dragon would they still be able to cast spells?

Can a Solarian’s ability to enter a Stellar Mode take into consideration conditions affecting her?

I know there is GM discretion allowed as to the situations affecting a Solarian’s ability to enter a Stellar Mode, but I would like other GMs opinions on this situation.

RAW seem to generally require that the Solarian be "in combat" and facing a significant threat. In fact, the description specifically says that:

you must be facing a significant enemy (see page 242).

Description of Significant Enemy:

…a creature with a CR less than or equal to your character level – 4 is not a significant enemy

So… nowhere does it give consideration as to the Solarian’s personal situation.

In a hypothetical situation even a lowly CR-1 creature would present a dire threat to a Paralyzed 6th level Solarian, but she would not be permitted to enter Stellar Mode and become attuned, to use her Corona Revelation as a defense because of the low CR rating of the enemy.

In our example situation, the party encountered a group of Ghoul Soldiers who managed to paralyze the Solarian via bite. Combat moved into the next room, leaving the Solarian alone and still paralyzed (for 2 more rounds). I presumed the Solarian’s Stellar Mode ended because there was no current threat to her, and stated such. She argued that the state of paralyzation itself constituted a threat and/or the fact that I still had her in "melee round" mode meant she was still "in combat" (she wanted to become fully attuned so she could jump back in the fight if/when released from paralyzation). I ruled that it must be a threat from an enemy and that her Stellar Mode ended, but she was still in "melee mode" so I could track the rounds of her paralyzation; she was unhappy with this decision.

When are Ability Scores (not modifiers) used in D&D 5e?

In D&D, the main ability is a score from 1-30, while the modifiers range from -5 to +10 (score -10/2 round down)

In the Player’s Handbook, it states:

Because ability modifiers affect almost every Attack roll, ability check, and saving throw, ability modifiers come up in play more often than their associated scores.

So when do the scores come up?
