Is the star chart a material component for the Guidance and Guiding Bolt spells from the Circle of Stars druid’s Star Map feature?

The Circle of Stars druid’s Star Map feature grants the following benefits (TCoE, p. 38):

You’ve created a star chart as part of your heavenly studies. It is a Tiny object and can serve as a spellcasting focus for your druid spells. You determine its form by rolling on the Star Map table or by choosing one.

While holding this map, you have these benefits:

  • You know the guidance cantrip.
  • You have the guiding bolt spell prepared. It counts as a druid spell for you, and it doesn’t count against the number of spells you can have prepared.
  • You can cast guiding bolt without expending a spell slot. You can do so a number of times equal to your proficiency bonus, and you regain all expended uses when you finish a long rest.

Neither guiding bolt nor guidance have a material component. It would seem from the language that RAW one must hold the chart in one hand and cast these spells with the other, unless one has the War Caster feat.

Is my interpretation of the rules correct? And what is actually intended?

Is the star chart a material component for guidance and guiding bolt?

Using Divination Spells for Droskar’s Guiding Ring

Here is the description of Droskar’s Guiding Ring:

This gold ring is misshapen and uncomfortable to wear for long periods of time; inscribed on it is a crude symbol of a fire burning under an arch. Once per day, the wearer may use charm person. If Droskar is the wearer’s patron deity, any time the wearer crafts a magic item, she may choose to pay half of the item’s construction cost instead of the full cost. The wearer spends time working on the item normally, but at the time of completion there is a 50% chance that the item turns out nonmagical and worthless. For example, if creating a magic bracer that normally costs 1,000 gp to craft, the wearer may craft it for only 500 gp, but there is a 50% chance the wearer’s shortcuts and cheap materials result in a valueless, nonfunctional item.

The description of Divination:

Similar to augury but more powerful, a divination spell can provide you with a useful piece of advice in reply to a question concerning a specific goal, event, or activity that is to occur within 1 week. The advice granted by the spell can be as simple as a short phrase, or it might take the form of a cryptic rhyme or omen. If your party doesn’t act on the information, the conditions may change so that the information is no longer useful. The base chance for a correct divination is 70% + 1% per caster level, to a maximum of 90%. If the die roll fails, you know the spell failed, unless specific magic yielding false information is at work.

As with augury, multiple divinations about the same topic by the same caster use the same dice result as the first divination spell and yield the same answer each time.

The description of Augury:

An augury can tell you whether a particular action will bring good or bad results for you in the immediate future.

The base chance for receiving a meaningful reply is 70% + 1% per caster level, to a maximum of 90%; this roll is made secretly. A question may be so straightforward that a successful result is automatic, or so vague as to have no chance of success. If the augury succeeds, you get one of four results:

  • Weal (if the action will probably bring good results).
  • Woe (for bad results).
  • Weal and woe (for both).
  • Nothing (for actions that don’t have especially good or bad results).

If the spell fails, you get the “nothing” result. A cleric who gets the “nothing” result has no way to tell whether it was the consequence of a failed or successful augury.

The augury can see into the future only about half an hour, so anything that might happen after that does not affect the result. Thus, the result might not take into account the long-term consequences of a contemplated action. All auguries cast by the same person about the same topic use the same die result as the first casting.

Could one use Augury or Divination to predict the result of Droskar’s Guiding Ring, allowing an almost 100% success rate with it?*

*Especially if you use something like Messenger of Fate to get a 100 percent success rate with your divination spells.

How does guiding bolt work on an invisible target?

Most spells state the target as something you can see. for example the magic missle spell says :

Each dart hits a creature of your choice that you can see within range.

But recently I saw that the guiding bolt spell does not. It states this:

Make a ranged spell attack against the target.

I was wondering how this targeting works against invisible creatures.

lets say we are in a closed of room with an enemy, they turn invisible and we have no idea where they are. We know he is still in range because the room is very small.

Can I cast guiding bolt and just say, “I target the invisible creature in this room” or do I actualy need to know where they are?

Creating a ‘Scroll of Guiding Bolt’ and how it would work

tl;dr: Would a scroll of guiding bolt use my main spell attack bonus(Int), my lower cleric spell attack bonus(Wis) or no bonus at all.

I’m playing an Artificer Archivist(8)/Forge Cleric(2) in a short campaign and I was trying to figure out how or if it is possible to create a ‘Scroll of Guiding Bolt’ (or any other spell from either class list) and if it is, which spell attack block would it use for any given spell scroll.

First off Xanathar’s… Page #133.

SCRIBING A SPELL SCROLL

With time and patience, a spellcaster can transfer a spell to a scroll, creating a spell scroll. Resources. Scribing a spell scroll takes an amount of time and money related to the level of the spell the character wants to scribe, as shown in the Spell Scroll Costs table. In addition, the character must have proficiency in the Arcana skill and must provide any material components required for the casting of the spell. Moreover, the character must have t h e spell prepared, or it must be among the character’s known spell s, in order to scribe a scroll of that spell. If the scribed spell is a can trip, the version on the scroll works as if the caster were 1st level.

Artificer – Archivist Subclass

Tools of the Trade:

Proficiencies. …You gain proficiency with calligrapher’s supplies and the forgery kit…

Crafting. If you craft a magic item in the scroll category, it takes you a quarter of the normal time, and it costs you half as much of the usual gold…

Finally, Is 1 day of work classed as 8hrs of work? If so, does that mean That 1/4 of the time and 1/2 the cost translates to a scroll of guiding bolt taking 2hrs and 13gp?
