When casting Faerie Fire from Ring of Shooting Stars, do you need to maintain concentration? [duplicate]

Ring of Shooting Stars says

Faerie Fire: You can expend 1 charge as an action to cast Faerie Fire from the ring.

Since it says you cast the spell from the ring, I wonder if you need to maintain concentration on the resulting spell. Moreover, is that something particular to Ring of Shooting Stars, or is that how it usually goes with casting spells via items?

Does Ranger Monster Hunter’s Slayer’s Counter works on saves to maintain concentration?

From the Sage Advice Compendium:

Does a Monster Slayer ranger’s Supernatural Defense feature apply if a creature damages the ranger, thus causing the ranger to make a Constitution saving throw to maintain concentration on a spell? Yes.

Since the Supernatural defense works for concentration, does the Slayer Counters works as well?

Does the Fade Away gnome racial feat require concentration?

Does the invisibility that the Fade Away racial feat (for gnomes) grants require concentration or would using it drop any spells the user is currently concentrating on?

The wording doesn’t specifically say that (you become invisible, you don’t cast the invisibility spell). I am unsure of how it works, and can’t find the answer online. How does Fade Away work?

Does the Elemental Gem require Concentration?

Does an elemental summoned from an Elemental Gem require Concentration? I am getting hung up on the "as if you had cast" part. Other items say, "you can use an action to cast the [spell]".

Elemental Gem

This gem contains a mote of elemental energy. When you use an action to break the gem, an elemental is summoned as if you had cast the conjure elemental spell, and the gem’s magic is lost. The type of gem determines the elemental summoned by the spell.

The distinction I’m asking then is if the Elemental Gem is a spell or a spell-like effect.

If wild shape ends by falling to 0 hp, does the druid lose concentration? [duplicate]

A druid that is wild shaped reverts "when" they drop to 0 hit points. Does that mean other effects that occur when a creature drops to 0 hit points also occur (though possibly in any order of the druid’s choice)? Specifically, if the druid were concentrating on a spell, would dropping to 0 hp – even momentarily – suffice to cause the druid to lose concentration by being incapacitated?

I can’t figure out what RAW or RAI is on this one – does anybody have any pointers (e.g. a rule or rule interaction I missed, or some sage advice)?

Does the Psi Warrior’s Psionic Strike ability prompt a second Concentration save?

The new Psi Warrior Fighter subclass has the feature Psionic Power which has the following option:

Psionic Strike. You can propel your weapons with psionic force. Once on each of your turns, immediately after you hit a target within 30 feet of you with an attack and deal damage to it with a weapon, you can expend one Psionic Energy die, rolling it and dealing force damage to the target equal to the number rolled plus your Intelligence modifier.

Based on my earlier question it seems the consensus is that Psionic Strike does not double if the triggering attack is a critical hit.

If Psionic Strike is used on a creature concentrating on a spell does the additional damage prompt a second Constitution save to maintain concentration?

Concentration and Shapechange 5e [duplicate]

I’ve been trying to make use of the Shapechange spell as a 9th level spell with a Druid class, but concentration seems to be a major issue. Say I transform into a Phoenix, can I use the 3 Legendary Resistance to automatically succeed in a damaging saving throw three times to prolong the form? This would make Shapechange viable for melee characters for atleast a slightly longer period than a single turn.

Does this build make it possible to use two concentration spells at once? [closed]

My DM told me to make a 2nd level character, which he approved, and it was a wizard 1, sorcerer 1 with draconic bloodline. I was a dragonborn so I thought I could be a melee wizard with some fun little caster tricks when I stumbled upon this new trick.

I planned to make the character Wiz10/Sor10, using tenser’s transformation. I wanted a weapon to enchant myself, so I planned for a greatsword, with glyph of warding. Of course the glyph can only move 10 ft, so it didn’t seem very practical at the time… until I thought of something.

The bag of holding. It seemed like the perfect idea, but it was too big, eventually I came across the handy haversack, and since it makes an extra-dimensional space, the glyph wouldn’t technically move.

So if you have a weapon enchant it and its hilt with Tenser’s transformation and another self-concentration spell, quicken-step metamagic another concentration spell, could you use three different concentration spells at once. Given that you set the activation requirement to a command word and drawing the sword?

Can you maintain concentration through a short rest?

Due to the long duration on Hex, it is clearly intended to function across multiple encounters as described in this answer.

Due to the extended duration, it seems feasible that a warlock could take a short rest to recover their spell slot and thus go into a future combat with a Hex at the ready and a full assortment of spell slots. Is this correct? RAW do not appear to prohibit this.

as a Sorcerer, given that I can’t multiclass or take feats, how successful can I be at passing concentration checks starting at level 15 [closed]

I’m doing a melee sorcerer, but I’m afraid of losing my concentration in combat because in the higher levels the damage is too big and the concentration check is too difficult.
My campaign dosen’t allow feats and multiclassing, only ASI.
Is the haste spell worth it at higher levels?

not worth it to cast only to lose it in one round because I was hit and lost concentration – that’s what I mean by "Is it worth it?"
