Hi! Opted to sneak in from the CurseForge page~

I had an initial idea to restore primordial pearls with Impetus (I think you can see it by looking into the edits, right, but I'm replacing it with a selection of things:

Spell Modifier: Amplify
-This modifier, well, amplifies the power and effects of any Target effect placed after it (allowing, for example, a max power Air spell to hit even harder, and have more knockback, than it could by itself); it does, however, add an Impetus cost to your spell, so you must have it stored in your gauntlet along with having the available vis to cast the spell. (If the spell would Already have an impetus cost, Amplify simply increases that impetus cost.)
-Similarly to Scatter, you can only have Amplify once in a single focus.

Spell Trajectory: Pillar
-This trajectory places a circle on the ground that quickly fires off a column of energy into the air above it; this pierces through entities, and everything hit by this pillar is affected by your spell. You can modify how high the pillar is (from a minimum of three blocks high to as high as 5-6 blocks), and increase the number of pillars the spell casts (so that, instead of one pillar, you can create a several of them in a line, or around the target, firing off in rapid succession).
-Vis Shard: (I'm torn between Vitreus, Volatus, and Praecantio; thoughts?)

Spell Trajectory: Stickybomb
-A modified Arcane Mine that sticks- to blocks, to monsters, to entities. When the Caster's Gauntlet is shift-clicked, every stickybomb you cast automatically detonates, applying all of their spell effects at once.
-You may choose whether you have to be looking in the direction of these mines to detonate them, or if they will regardless when you shift-click.
-You can only have eight stickybombs active at one time.
-Vis Shard: probably Desiderium (since the regular Arcane Mine already has Vinculum, right? Again: thoughts?)

Impetus Hand Mirror (Warping 2)
A modified Magic Hand Mirror that can be linked to an Impetus Mirror. While that mirror has Impetus flowing through it (or can otherwise accept Impetus from a source), the Impetus Hand Mirror will take a portion of it to charge Impetus items in the player's inventory. The charge rate is quite slow, however, and it and gives you warp now and then as it draws Impetus. Might be a good idea to have a less... otherly mirror on hand for when you need to fix your hair.

Primordial Soup
Here's the idea that replaced my original one:
What if, instead of repairing primordial pearls, we have a machine that uses Impetus to melt them? Into a liquidy, fluidy substance called Primordial Soup; how much Soup you get from this depends on the pearl-- you get one point of Primordial Soup for each point of durability the Pearl you melted had.
-Primordial Soup goes into phials and jars like your regular Thaumcraft Essentia, and it's treated as such in respect to infusions, but it's... weird. You can't overfill void jars with this stuff (they will explode, dumping a Lot of flux into the environment), running Soup through an Essentia Centrifuge will net you any of the Primal aspects basically at random, feeding it into a Flux condenser could be interesting, and feeding it into a Flux Rift in lieu of Vitium might be a big mistake (I'll leave it to open discussion what happens, if anything!). In general though, Primordial Soup should have some odd interaction with nearly every compatible machine around that accepts Essentia-- whether awesome, nifty but not really practical, or even downright disastrous; feel free to suggest possibilities~
-As a Vis Crystal, Primordial Soup may have some use for some sort of final spell component, but I think it's more likely to just be 'stackable' Primordial Pearls-- each Primordial Vis Crystal being usable for one craft only.
-In regards to infusions, Primordial Soup would be used for creating the final, strongest items of the mod-- of which I have only one to suggest (read below); maybe it could offer bigger Vis batteries as well, or something. Or the Primordial Soup can be applied as a special wildcard that can 'fill in' for a missing type of Essentia if you find yourself running low of something important (note that this only works if the altar doesn't require Primordial Soup itself for its infusion; if it does, you do need to cover everything yourself as the soup Already has a designated place in the infusion). What do you think?

The Eldritch Embroider (Warping 6)

A massive pair of scissors, as tall as the player is, that doubles as a staff; it needs to be charged with Impetus to function. In addition to dealing a lot of damage when you hit things with it, it has four modes of operation:

-Resonator: In this mode, the Eldritch Embroider acts just like an Impetus Resonator (you can also interact with Essentia Tubes, the Infusion Altar, and other machines like you would with a Caster's Gauntlet).
--If you hold shift-click on a device that accepts Impetus, like the Void Siphon or Impetus Drainer, you can feed it some of the Embroider's Impetus. Useful for testing or troubleshooting your Impetus setups.
--One last thing: Shift-click a block that can have Salis Mundis applied to it to do so, free of charge.

-Riftweaver: When you hold shift-click with the Riftweaver mode, the Embroider expends some of its Impetus to form a small flux rift in front of you. Holding click on the rift causes the Eldritch Embroider to spend its Impetus to grow the rift in size (switch modes to drain Impetus from the rift again; you get roughly 60% of your Impetus back). Forming a flux rift with the Eldritch Embroider gives you warp (could be between 4-12 temporary warp and 1-3 sticky warp; thoughts?).

-Dimensionweaver: The Eldritch Embroider spends Impetus to open a temporary fracture into the Emptiness (or from the Emptiness, into the Overworld)-- it closes behind you after the caster enters it, or after a minute if left unattended. If you wish to tear fractures to other dimensions besides the Emptiness, you can do so with Dimension Signatures (separate research). You can store up to 5-6 Dimension Signatures in the Riftweaver at once, to permit creating fractures to other dimensions (scroll through these in a menu akin to the one for selecting between spell foci to choose your preferred destination). Forming a dimensional fracture also gives you warp (same amount as in the Riftweaver mode).

-Spellweaver: The Eldritch Embroider has a receptacle in its joint that can accept Spell Foci much like your Gauntlets can, and it can cast spells in this mode. In the Emptiness, it casts spells with a 50% vis efficiency bonus and twice the reduced cooldown that the Thaumium Caster's gauntlet has... though in any other dimension, it is barely better than the mundane Caster's Gauntlet (5% vis efficiency, no reduced cooldown). This, along with the fact the Riftweaver Scissors cannot accept Gauntlet augmentations, may make it worthwhile to have a dedicated Gauntlet to cast spells with alongside the Embroider.
-An alternate possibility for the Spellweaver mode is that while it has the flat 50% vis bonus and further reduced cooldown while in the Emptiness, its performance elsewhere depends on how much Impetus it has; at no Impetus, it has exactly the same preformance as the mundane Caster's gauntlet. As it fills up, then (along with the slight bonus having Impetus does for foci in general), it gains up to 10% vis efficiency bonus, though again with no- or a lesser- cooldown in comparison to the Thaumium Caster's Gauntlet. In general, though, as a spellcaster the Eldritch Embroider should be the best caster in the Emptiness alone, and alright elsewhere (though the two upgradable Gauntlets can both surpass it when the Embroider no longer has the home field advantage!).

--(Sidenote: For ease of configuration, the Eldritch Embroider applies its spell bonuses in every dimension the Dimension Modifier: Emptiness is configured to apply to. The dimensions the Embroider can create portals to can also be blacklisted/whitelisted, though by default it can reach any dimension.)
--(Additional possible modes: block-breaking mode, broomstick/flight mode. I'm not currently taking these seriously right now, but I'll mention them just in case, yeah?)
--And yes, this item is one big reference. Can you guess to what?

Dimension Signature
Secondary research that goes along with the Eldritch Embroider. Shift-right click to bind the Dimension Signature to the dimension that you're in (if it's already bound to a dimension, you simply rebind it to the current one). The Dimension Signatures can be added/removed to the Eldritch Embroider in the same way that all Augments are.
-Precise Dimension Signature
This modification to the Dimension Signature allows your fracture to link directly to the location you bound the Signature, as opposed to just the same dimension as the Signature-- though this greatly increases the Impetus cost of creating a fracture to your destination.

Mm, true.

I don't know- I'm just looking for some sort of reason as to make Impetus more important generally for moving into endgame Thaumcraft, or even just to tie it in with other things in a greater modpack; I've expressed this particular sentiment already on the Curseforge page in the past, but nothing absolutely requires the use of Impetus in its creation; if I, for example, opted to gate a particular item behind an Impetus item (say, the regular Impetus Relay) in a recipe, you can just accomplish the respective research, craft the item for use in the recipe, and not worry at all about seriously using the system its tied to, you know?

Maybe we can shape the primordial pearls into shards or crystals or something, like-- what was it, the old Witching Gadgets (correct me if I'm wrong, I don't quite remember?)-- but so far, every use we have for Impetus, along with a few I've seen suggested, are handy but ultimately optional. I'd like to have a way to require players to set up and maintain an Impetus system for progression of some kind: perhaps to "entice" Thaumic Additions into a more balanced position with this specialized crafting material, or to just tie Impetus in to a larger modpack's progression, yeah? Plus, if you have to dabble in Impetus systems to get this one particular item anyway, why not venture into all the other neat things it can do for you as well?

I realize I'm moving away from the initial suggestion I brought up, though-

"I'm moving this." ~The Engineer

To the top of the page. Also, I've reworked what my ideas thread is for: what do you think?

I think that it would be easier to just farm Primordial Wisps for nodules than doing all that; at the end of the day the cost for one is just 2 rifts and at least 1 reinforced jar which are dirt cheap in the endgame.
