Can you use Magic Initiate to cast a spell you already know, and still learn another spell?

I have a wizard PC who wants to gain the feat Magic Initiate and use free 1st level spell to use mage armour once a day. He already knows Mage armour, so:

  1. Can he use the Feat to gain a free casting of Mage armour once each day?
  2. Should he get another 1st level spell but not get to freely cast it once a day?

Limite the amount of Ram mathematica can use and still get sensible results?

The question is very similar to this one, however the solution proposed there doesn’t satisfy me because I don’t want mathematica to abort the evalution, but simply to do it with less ram.

Basically I’d like mathematica to think my machine has for example only 14 Gb of ram and let him use only those, and not abort the evaluation when it uses more than 14, like suggested there.

Is this possible?

If it is possible, can I trust the results obtained in this way or there’s an high chance of losing important pieces during the evalution, due to the fact that mathematica would use more ram to perform that evaluation?

Does the Armor of Agathys spell still damage attackers if you have temp HP from another source, such as the Dark One’s Blessing feature? [duplicate]

This question already has an answer here:

  • How does Armor of Agathys interact with getting temporary hit points? 3 answers

Recently, I played a warlock in a 5e one-shot. We were playing at level 7 and I was a Pact of the Blade warlock with the Fiend patron. As a Fiend Warlock, I have a feature called “Dark One’s Blessing”, :

Starting at 1st level, when you reduce a hostile creature to 0 hit points, you gain temporary hit points equal to your Charisma modifier + your warlock level (minimum of 1).

The description of the Armor of Agathys spell reads:

A protective magical force surrounds you, manifesting as a spectral frost that covers you and your gear. You gain 5 temporary hit points for the duration. If a creature hits you with a melee attack while you have these hit points, the creature takes 5 cold damage.

At Higher Levels. When you cast this spell using a spell slot o f 2nd level or higher, both the temporary hit points and the cold damage increase by 5 for each slot level above 1st.

The situation was that there was a pack of ‘minions’ (4th-edition term, I know… but they were low-AC 5 hp monsters that died in 1 hit most of the time) attacking my group. The dragonborn wizard knew Fly, and grabbed the halfling and flew out of reach of the group of minions; I was left there with Armor of Agathys cast on me at level 4, so I had 20 temp hp and did 20 damage to each minion.

The question comes from the functionality of Temp HP (THP)… It does not stack. Instead, you must choose which set to acquire, either keeping the THP you currently have or using the new number provided by whatever is trying to give you more THP.

Once I was below 20 THP from the attacks made on me by this swarm of minions, I started taking the 10 (warlock level + CHA mod= 7+3) THP provided by Dark One’s Blessing. After rereading Armor of Agathys today, I noted it says ‘while you have these hit points’… leading me to believe that choosing to take the 10THP from Dark One’s Blessing would remove the Armor of Agathys and its damaging capability.


Does Armor of Agathys only work if you have THP from the spell specifically, or does it still work if you gain more THP from another source (like from Dark One’s Blessing) while the spell is still active?

If you are pushed out of Evard’s black tentacles while restrained, are you still restrained?

In our game, a monster was restrained by a party member’s spell, Evard’s Black Tentacles. The wording of the spell is:

…the creature must succeed on a Dexterity saving throw or take 3d6 bludgeoning damage and be restrained by the tentacles until the spell ends.

On the next turn, the Warlock Cast Eldritch blast, which is affected by the Repelling Blast Invocation. The invocation causes a creature hit by the spell to be pushed back 10 feet. However, this caused the monster to be pushed outside of the effect of Black Tentacles. The wording for the spell seems to imply that the tentacles are still miraculously restraining the creature though, which is now 15 feet outside of the area of effect.

Should the monster still be restrained or not? Are the tentacles in fact made of silly putty, or do they happen to have the powers of Mr. Fantastic?

For reference this question may have relevance. It references the Web spell, but the wording for this spell is more specific. It states:

…the creature is restrained as long as it remains in the webs or until it breaks free…

For reference, The Black Tentacles spell is a whole 2 levels higher than the Web spell.

What happens when the UA Bait and Switch maneuver is used on a grappled ally when both the user and ally are still within the grappler’s range?

This question is based on this one: What happens when the UA Bait and Switch maneuver is used on a grappled ally when the maneuver-user is out of the grappling monster's reach?

The Unearthed Arcana Class Feature Variants includes the Bait and Switch fighter maneuver (page 5), which states:

When you’re within 5 feet of an ally on your turn, you can expend one superiority die and switch places with that ally, provided you spend at least 5 feet of movement. This movement doesn’t provoke opportunity attacks […]

What happens when the Bait and Switch maneuver is used on a grappled ally when both the maneuver-user and the ally are still within grapple range of the grappling creature?

I see two possible outcomes:

  1. The maneuver-user takes the ally’s place in being grappled, and can then attempt to break out of that grapple.

  2. The ally is still grappled, but has now been possibly moved to a more beneficial position.

I am not sure which of these would happen, as normally in a grapple the grappled creature cannot ever move. (And I might be confusing myself by trying to think of how this would even work IRL.)

How to be able to still view Encrypted files on Samsung S9/Android, but not outside of it

I had lost a phone once and I was more upset with the idea of the bad guy having access to my Micro SD memory card/personal data than losing the phone itself.

After getting a new phone, Samsung S9 has a Encryption feature for SD cards, but the thing with this is, it won’t allow viewing of files unless it goes through the long process of Decrypting it on the phone.

I want a way to still be able to access encrypted files on the phone itself, but will require a password to decrypt/view outside of the phone (if the memory card was removed and tried being viewed on a computer for example, that this would not be possible).

Any possibilities?

Would I still be able to cast conjure barrage if I was also using flame arrow?

Conjure barrage specifies that the ammunition used to cast it must be non magical but I can’t find anywhere if an arrow under the effect of flame arrow is considered magical or not.

What I mean by that is, is the arrow in and of itself magical or does flame arrow just set it on fire as it’s launched as though it had been warped in cloth soaked in oil and lit (but without those steps)?

Would I still be able to use it as a medium to cast the conjure barrage spell or would I not be able to cast that till I lost concentration on flame arrow/the spell ran its course and if not would the effects stack?
