Can the artificer’s spell-storing item affect a Rakshasa?

My character is being hunted down by 3 Rakshasa. The character is aware they possess limited magic immunity which reads as follows:

Limited Magic Immunity. The rakshasa can’t be affected or detected by spells of 6th level or lower unless it wishes to be. It has advantage on saving throws against all other spells and magical effects. [Basic Rules, p. 341]

As a level 11 Artificer, I can store spells into a Spell-Storing Item.

Spell-Storing Item

At 11th level, you learn how to store a spell in an object. Whenever you finish a long rest, you can touch one simple or martial weapon or one item that you can use as a spellcasting focus, and you store a spell in it, choosing a 1st- or 2nd-level spell from the artificer spell list that requires 1 action to cast […].

While holding the object, a creature can take an action to produce the spell’s effect from it, using your spellcasting ability modifier. […] [ERLW p. 58]

Since the item is just "producing the spell’s effect" should it be treated as a magical effect instead of a 1st or 2nd level spell?

Is the Rakshasa immune to the spells produced by the item? Or would they just have advantage against saving throws?

What inspired the D&D version of the Rakshasa?

Rakshasa have been part of D&D for more than 35 years, appearing in every edition. These evil magic cat-people are clearly inspired by the rakshas from Hindu and Buddhist mythologies, but they have elements which indicate another source as well: so far as I can tell, backwards hands are not part of the original rakshasa concept.

  • Is there any knowledge of where this bit of backwards-hands/feet lore came from and why it was tacked on? I’ve found similar traits in creatures from many different cultures, but nothing that indicates to me one of them is more likely to be the actual inspiration (nearly all of them have backwards hands and feet, for instance).

I’m quite aware that often the answer to “why did D&D do this?” is “Gygax just did it,” or just a baffled shrug. But given the number of interviews and living information available, I’d like to get something more concrete. So although speculation may be all that’s available, I’m holding out hope for some “origin of” D&D magazine article or a similar source that draws a non-speculative line of influence from inspiration to monster.

[Context: I want to use creatures inspired by D&D rakshasa in non-D&D RPGs, and it’s important to me that I go to sources rather than simply plagiarizing D&D’s ideas.]

Innate Spellcasting vs Rakshasa

If a creature with Innate Spellcasting tries to use an innate spell against a Rakshasa, how does it interact with their limited magic immunity?

Limited Magic Immunity: The Rakshasa can’t be affected or detected by Spells of 6th level or lower unless it wishes to be. It has advantage on Saving Throws against all other Spells and magical Effects.

Do innate spells have a level?

How does a Rakshasa deal with sleeping when relying on the “Disguise Self” spell?

Rakshasa is a good infiltrator because of his at will disguise self. But he should sleep sometimes.

The problem is that this spell lasts for only one hour.

How does a Rakshasa hide his true form from possible observers when he is sleeping?

He has no special wording like undeads or constructs do like “Undead Nature. A wight doesn’t require air, food, drink, or sleep.” So he surely sleeps.

How do Stylized Spell (Metamagic) and Rakshasa Bloodline Arcana interact?

Both mechanisms are all about lying on what you are casting.

Bloodline Arcana:

Add half your sorcerer level to the Spellcraft DC for others to identify spells you cast. If their checks fail by 5 or more, they mistakenly believe you are casting an entirely different spell (selected by you when you begin casting).

So of course as False Priest I always disguise Aid as Cure Light Wounds. Plain and simple.

I’m considering obtaining more options via Stylized Spell (Metamagic):

Benefit(s): A stylized spell has slightly different verbal and somatic components than normal, and the spell effect appears noticeably different. The Spellcraft DC to identify a stylized spell as it is being cast is 10 higher than normal.

The Knowledge (arcana) DC to identify a stylized spell, its effects, or the materials it creates is 10 higher than normal, as is the DC to recognize your magical signature with greater detect magic.

When you apply this feat to a spell, you can attempt to disguise your stylized spell as another spell of the same school and subschool with the same descriptors. The other spell must be either the same spell level as the stylized spell (before applying the metamagic adjustment) or 1 spell level higher. If you do so, the stylized spell gains the ruse descriptor and takes on some superficial aspects of the other spell. As usual for a spell with the ruse descriptor, identification attempts that fail by 10 or less mistakenly identify it as the chosen spell (those that fail by more can’t identify it at all).

I want this for Apparent Source of Magic option, to make it look totally divine.

So do I have to use Stylized Spell to make my Aid look like divine Aid, and then Bloodline Arcana to make it look like Cure Light Wounds? What would the DCs be? And effects of failing by 5 or 10? (Say 6th level Sorcerer with 20 Cha, for example)

How does it look RAW, and do you have any experience about streamlining RAW if it turns out to be too complicated to be fun?

What spells can be used to damage a Rakshasa before L7 slots are available?

I’ve been looking for the most effective ways to damage a Rakshasa as a spellcaster, before L7 slots become available. After reading the 3 questions below,

  1. Is a Rakshasa immune to Animate Objects?
  2. Can Maximilian's Earthen Grasp or Bigby's Hand target a Rakshasa?
  3. Does a Mundane Arrow Fired From a Magical Bow Count as a Magical Weapon Attack?

I’m wondering if the following spells will work:

  1. Magic Weapon: Per the last question, my reading is that a Wizard could cast this on a crossbow (or bow, if they have proficiency), and deal semi-decent damage (assuming they are good aligned, it would target the R’s vulnerability).
  2. Alter Self (Natural Weapons, Piercing): Similar idea, available to other classes, though would require going into melee (not so problematic due to damage, but due to Curse).
  3. Elemental Weapon: Similar idea, though I’m not sure if the bonus elemental damage applies.
  4. Shillelagh: Doesn’t target the R’s vulnerability, but a Druid could go this route if desperate for damage.

Are there other (better?) ways for casters to damage this sucker before L7 slots are available?

Note: I’m aware that buffing/assisting is another way to contribute to the fight–I’m interested specifically in offensive options available.
