Needlekind

needlekind is Rose Lalonde's main Strife Specibus. At first this kind abstratus was just normal needles, but Rose has since alchemized needles that function as magic wands.

Knitting Needles
These needles were given to Rose by John for her birthday, because he thought she needed a normal hobby. She first uses them (passive) aggressively in a Strife against her Mom, in which she threatens to electrocute herself using them. When Rose reaches the Land of Light and Rain she uses the needles in combination with the wool very effectively, easily taking down Imps and even a Lime Ogre.

She also uses them to actually knit things, like the head and arms of the Eldritch Princess or a laptop cozy or parts of the bunny she later gives to John.

Needlewands
A pair of needles created with the Alchemiter. Rose has not used these in battle since their creation, as she made the considerably more powerful Thorns of Oglogoth by combining them with her Grimoire immediately after creating them. They're quite useful for burning things, though.

Thorns of Oglogoth
An item alchemized from the Needlewands and the Grimoire for Summoning the Zoologically Dubious. These seem to be powerful weapons, capable of punching holes in chalk liches from a distance.

While it was inevitable that Rose would receive thorns, the description of these ones notes that any sane adventurer would drop them and flee. In unrelated news, Rose acquired the Thorns of Oglogoth late in Act 4 and may have ended the act by going batspit crazy.

It is very possible that the Thorns are having a negative effect on Rose psychologically, probably because of the powers of the Grimoire. Later in Act 5 she is seen as more cold, almost mean, hinting that the Thorns have affected her in some way. A similar theory is supported by Rose's conversations with Kanaya, who expresses uneasiness with Rose's apparent allegiance with The Noble Circle of Horrorterrors and her frequent and almost brash usage of dark magic in tearing apart her own planet.

Quills of Echidna
The Quills of Echidna are weapons first seen strapped to the back of the version of the bunny that Jade gave to John. The needles look like white lightning and are interestingly named after the browser used by Jade Harley, Echidna, and accordingly, may be related to Jade's denizen, much in the same way John's Fear No Anvil is related to Dave's denizen.

Of note, the Echidna of Greek mythology was the mother of all monsters, and thus the name may be a reference to Rose's interest in the occult. Additionally, the real-life animals called echidnas have hedgehog-like quills, making the name a multi-layered reference.
