Can the blade created by Shadow Blade be used with the Booming Blade or Green Flame Blade cantrips?

The spell shadow blade allows a spellcaster to produce a discrete weapon that can then be used to make attacks:

You weave together threads of shadow to create a sword of solidified gloom in your hand. This magic sword lasts until the spell ends. It counts as a simple melee weapon with which you are proficient. It deals 2d8 psychic damage on a hit and has the finesse, light, and thrown properties (range 20/60). In addition, when you use the sword to attack a target that is in dim light or darkness, you make the attack roll with advantage.

Shadow Blade, Xanathar’s Guide to Everything, pg. 164

As part of recent errata to the green-flame blade and booming blade cantrips, their material components have been amended to "a melee weapon worth at least 1 sp" (Sword Coast Adventurer’s Guide, 142).

Can shadow blade still produce a weapon that can be used with these cantrips?

Can a monster cast a higher level spell using a lower level spell slot? (Shadow Fey Enchantress)

Is there a (monster creation) rule that allows a higher level spell to be cast using a lower level? I ask because I came across the "Shadow Fey Enchantress" (Kobold Press "Tome of Beasts", pages 170-172), as it states:

Spellcasting. The shadow fey is a 10th-level spellcaster. Her spellcasting ability is Charisma (save DC 15, +7 to hit with spell attacks). She knows the following bard spells.

Cantrips (at will): blade ward, friends, message, vicious mockery
1st level (4 slots): bane, charm person, faerie fire
2nd level (3 slots): enthrall, hold person
3rd level (3 slots): conjure fey, fear, hypnotic pattern
4th level (3 slots): confusion, greater invisibility, phantasmal killer
5th level (2 slots): animate objects, dominate person, hold monster

However, Conjure Fey is a level 6 spell: https://www.dndbeyond.com/spells/conjure-fey

Shadow Fey Enchantress, stats: https://www.5esrd.com/gamemastering/monsters-foes/monsters-by-type/humanoids/shadow-fey/shadow-fey-enchantress-3pp/

I checked with the Errata, but it doesn’t mention this as an error. Perhpaps it was overlooked, or perhaps there is a monster creation mechanic that I’m not aware of?

EDIT: Bonus points for a suitable replacement spell (if indeed an error)!

Does the disadvantage on saves from Shadow Sorcerer’s Hound of Ill Omen feature persist beyond the first turn?

Shadow Sorcerer’s Hound of Ill Omen feature’s text reads:

…Additionally, while the hound is within 5 feet of the target, the target has disadvantage on saving throws against any spell you cast. The hound disappears if it is reduced to 0 hit points, if its target is reduced to 0 hit points, or after 5 minutes.

I’m curious if against any spell you cast refers to the action of casting the spell, or the condition of having been a spell that you cast in any tense.

The difference being that a spell like Hold Person would only get disadvantage on the first saving throw with the first interpretation, but on all following saving throws with the second interpretation.

The only comparable feature that I know of is Heightened Spell, a Sorcerer metamagic, that reads:

When you cast a spell that forces a creature to make a saving throw to resist its effects, you can spend 3 sorcery points to give one target of the spell disadvantage on its first saving throw made against the spell.

This feature is clear in its intent, that only the initial saving throw against any spell is affected and given disadvantage.

The lack of clarification on Hound of Ill Omen makes me wary of which way to rule.

Can shadow sorcerer cast darkness using sorcerer points and metamagic at the same time?

I hope that the title is clear, but let me go a bit in detail.

Let’s say that I want to use the shadow sorcerer feature "eyes of the dark" to cast darkness using two sorcerer points. More, I would like to cast it as a bonus action, with quick spell metamagic option.

Is this possible? The final results is that the sorcerer cast darkness as bonus action, using 4 sorcerer points and no spell slot.

Thanks for any reply. (:

Can a wereraven shadow monk cast darkness in raven form?

In my ongoing Curse of Strahd game,

The question has arisen about what spells a wood elf Way of the Shadow Monk would have access to in the various wereraven forms.

In the humanoid (wood elf) form, all spell casting would be available as normal.

In the hybrid form, most spell casting would still be available, as the hybrid has hands (S), voice (V), and Ki (M). She would just need to remember to bring her fleece after all her gear drops to the ground when changing forms in order to cast minor illusion.

In the raven form, however, most spellcasting would be lost, as the bird does not have hands (S). However, one possible spell retained is darkness, which does not have a Somatic component and which instead is just V, M. The Material components are replaced with Ki, as described in the subclass’ abilities. But can the wereraven’s ability to Mimic serve as the Verbal component?

Mimicry. The wereraven can mimic simple sounds it has heard, such as a person whispering, a baby crying, or an animal chittering. A creature that hears the sounds can tell they are imitations with a successful DC 10 Wisdom (Insight) check.

Is this mimicry close enough to actual sounds that it could serve as the verbal component of the spell? Or is it just imitation sound, not actual ‘sounds of power, and insufficient?

Note that the ‘verbal’ component of spells derives its power not from the words themselves but because the words sound like powerful magical sounds

Most spells require the chanting of mystic words. The words themselves aren’t the source of the spell’s power; rather, the particular combination of sounds, with specific pitch and resonance, sets the threads of magic in motion.

This related question asks whether a wild shaped druid can speak in raven form. On the one hand, actual speaking would require far more verbal repertoire than casting a single action spell. On the other hand, perhaps the ‘sounds of power’ in a spell need to actually really spoken rather than just imitation sounds.

This related question concludes that Kenku can cast spells with verbal components, but it is primarily supported by a Crawford tweet that says "Kenku speak" and ravens seem more limited to me. At the level of mechanics, raven mimicry is detected by a DC-limited Insight check, while Kenku mimicry is detected by a contested Insight vs. Deception check, hinting that the Kenku is more personally in control of their ‘speech’ and some are better than others.

Can shadow arrow be used as a wand of enemy detection?

Magic exists which can divine the intentions of other creatures toward me.

"Wand of Enemy Detection"

While holding it, you can use an action and expend 1 charge to speak its Command Word. For the next minute, you know the direction of the nearest creature Hostile to you within 60 feet, but not its distance from you. The wand can sense the presence of Hostile creatures that are ethereal, Invisible, disguised, or hidden, as well as those in plain sight.

Arcane Archer: Shadow Arrow (emphasis mine)

You weave illusion magic into your arrow, causing it to occlude your foe’s vision with shadows. The creature hit by the arrow takes an extra 2d6 psychic damage, and it must succeed on a Wisdom saving throw or be unable to see anything farther than 5 feet away until the start of your next turn.

Abilities and Effects do what they say they do. There is no fluff in descriptions. As written, it appears that if I hit a creature with my Shadow Arrow, it does regular arrow damage plus 2d6 psychic damage. In addition, if the creature hit is my foe, it must make a Wisdom save or have its vision occluded.

Suppose I want to determine if an NPC of uncertain loyalty is my foe or not. I hit him with Shadow Arrows. If his vision becomes occluded, he must be my foe. If not, he is either not my foe or he has made his save.

  1. Does the Shadow Arrow really know who is my foe, similar to a wand of enemy detection, or does it assume that anyone I would shoot at must be my foe?

  2. If the latter, could an NPC that was trying to gain my trust volunteer to receive my arrow? Would that affect the result if they were being truthful? Deceptive?

  3. If my DM has me roll critical fails as attacks on allies when I fire into a melee, can I be confident that my shadow arrow will not be able to occlude the vision of anyone friendly to me?

Does the Arcane Archer’s Shadow Arrow inhibit blindsight, tremorsense, and/or truesight?

Shadow Arrow:

You weave illusion magic into your arrow, causing it to occlude your foe’s vision with shadows. The creature hit by the arrow takes an extra 2d6 psychic damage, and it must succeed on a Wisdom saving throw or be unable to see anything farther than 5 feet away until the start of your next turn.

Blindsight:

A creature with blindsight can perceive its surroundings without relying on sight, within a specific radius.

If a creature with blindsight (like a Flying Sword) fails its saving throw against an arcane archer’s Shadow Arrow, is its ability to perceive enemies via blindsight restricted? Would creatures with truesight or tremorsense be handled the same way?

It seems to me that this is fairly straightforward, but upon reading this question about opportunity attacks, there seem to be cases where the word "see" is used more generically as all forms of perception.

Is there a minimum requirement for a character to have line of effect with Shadow Jaunt/Stride/Blink?

I’m pretty sure this has been asked already but I can’t find the question in question, so I hope I don’t break any rules by asking again.

The Shadow X maneuvers from Shadow Hand have a line of effect and line of sight requirement to work. Let’s say I want to teleport through a hole in a wall. According to both line rules, as long as I can see though the hole and there is nothing obstructing the path though the hole, I should be able to teleport though it.

Is there a minimum size the hole has to be for my character to be able to traverse the hole?

Are Shadow Assassins proficient with Sawtooth Sabre?

Are Shadow Assassins proficient with Sawtooth Sabre?

In RAW, how proficient is the shadow assassin with the sawtooth sabre?

Weapon and Armor Proficiency
A shadow assassin is proficient in all simple weapons, all light weapons, as well as bolas, net, repeating crossbow (light only), shuriken, spiked chain, and whip. The shadow assassin is proficient with light armor and small shields, but not heavy shields or tower shields.

Sabre, Sawtoothed Category: [light] Proficiency: [exotic]
A sawtooth sabre may be used as a Martial Weapon (in which case it functions identically to a longsword).
If you have the Exotic Weapon Proficiency (sawtooth sabre) feat, for the purpose of two-weapon fighting you can treat it as a light melee weapon; for all other purposes, it is a one-handed melee weapon.

Here’s scenarios we’ve been discussing:

  1. SA can not wield SS proficiently, since the SS is an [exotic] weapon.
  2. SA can wield SS proficiently, but cannot use it as a [light] weapon due to lacking the Exotic Weapon Proficiency feat.
  3. SA can wield SS proficiently and as a light weapon, since the SS is a [light] weapon and SA have proficiency in "all light weapons".

If a dragon becomes a shadow dragon, would it still be subject to a previously cast True Polymorph’s reversal?

Story / example: A Harpy gets Truly Polymorphed into a wyrmling Brass dragon. Over eight centuries she eventually becomes ancient and powerful – albeit a bit weird with her harpy-like personality and alignment.

As an avid reader of StackExchange she becomes a bit paranoid. She is concerned: should a Magical Dispelling get past her three daily uses of Legendary Resistance she would, once again, be that stupid, nasty, dirty little girl with those grimy-grubby wings… that happens to sing quite well. As such, she plots.

She sends herself into some Shifting Planes, ending up in Fell Shadows. Assuming success, she becomes one Shadow Dragon creature / template / archetype / true dragon / thingy.

"Aha!" she shrieks with delight, "Now i am genuinely a dragon… a DRAGON FOREVER!! Take THAT, Exchangers of Stack!" The cold hard rain falls as lightning cascades in the distance ominously. Indeed, has this mere harpy of a girl outwitted us?


Question: Does a transformation into an entirely different creature (such as changing types &/or transforming bodies) mean that Dispel Magic cannot undo a ‘permanent’ True Polymorph spell? Or does this apparently-totally-‘new’-creature take this polymorphic-dispelability along with them?
