So now that I'm not double posting, I've got some bits and bobs from Discord that need mentioning here.
First, It turns out the correct setup for Renaissance Halo is 2 graces Gisena has seen, changable every 2100 hours. That's 87.5 Days or 3.2 Lunar Months. I'm going to presume Gisena does get Time Dilation benefits here from Auspice Temporal though, which moves the Renaissance Halo conversion time down to 3.125 weeks. Gisena presumably experiences 96 hours a day. 8 hours dilated to 80, plus 8 normal hours, plus 8 hours of sleep. 2100/96 is 21.875 days. 21.875 days/7 = 3.125 weeks. This can presumably be improved by getting Gisena more time dilation, whether by Haeliel showing up to teach Gisena, Gisena unlocking the time domain on her ring, or Gisena training Auspice Temporal.
So we know two Halos right now. And we know that there are two Haloes we don't know.
Halo Of Singularity - Quad Stats for Gisena(Hopefully if those aren't nullified), combined with nullification of magic within Gisena's Sphere of influence combined with the removal of all conceptual limits on technology. We'd presumably be down to the Praxis, our Meta-Ontology Powers, and our Forebear's Blade powers within her halo. We could use our meta-ontology to make technology to take advantage of the Singularity Halo.
Renaissance Halo - Quad Stats for Gisena. Lose access to Grace of the Glaze, Evoker's Panopoly, and Maiden's Whisper, for Gisena to reproduce any 2 graces she has seen, with a change time of 3.125 weeks given Gisena's current time dilation. These slots can be used for Grace of the Glaze or other components if necessary. Gisena's probably seen more graces then people think if everything Augustine tried on us counts as a Grace.
Industrial Halo - Capabilities unknown, presumably Quad Stats for Gisena at least
Enlightenment Halo - Capabilities unknown , presumably Quad Stats for Gisena at least.
Quad Intelligence seems like it would make Gisena an Ordinalism learning monster. She might even be able to get away with an Accelerate/Legion build. There may be room to squeeze in another elements ordinal or construct ordinal, but Ordinalism has skill maintenance demands. It's like playing a musical instrument. 1 Ordinal, 2 at most is smart from a specialization standpoint.
1. Shield
2. Construct(For Artifice Tools)
3. Elements(Metal)(For Artifice resources)
4. Elements(Earth)(For Artifice Resources)(110% Numerical Parameters of 4th Ordinal Baseline presumably)
5. Accelerate
6. Legion
7. Accelerate(110% Numerical Parameters of 7th Ordinal Baseline) - 1st Attainment = Imperia's Legion attainment for a mostly accelerate build with 2 Gisenas
8. Accelerate(121% Numerical Parameters of 8th Ordinal Baseline)
9. Accelerate(133% Numerical Parameters of 9th Ordinal Baseline)
10. Accelerate(146% Numerical Parameters of 10th Ordinal Baseline)
11. Accelerate(160% Numerical Parameters of 11th Ordinal Baseline)
12. Accelerate(175% Numerical Parameters of 12th Ordinal Baseline)
Or perhaps even this(If Gisena sacrificed half her mythology Halo gains to have 3 bodies, they would still be transcendent geniuses)
1. Shield
2. Construct(For Artifice Tools)
3. Elements(Metal)(For Artifice Resources)
4. Construct(110% Numerical Parameters of 4th Ordinal Baseline)
5. Accelerate
6. Legion
7. Accelerate(110% Numerical Parameters of 7th Ordinal Baseline) - 1st Attainment
8. Legion(110% Numerical Parameters of 8th Ordinal Baseline)
9. Accelerate(121% Numerical Parameters of 9th Ordinal Baseline)
10. Legion(121% Numerical Parameters of 10th Ordinal Baseline)
11. Accelerate(133% Numerical Parameters of 11th Ordinal Baseline)
12. Accelerate(146% Numerical Parameters of 12th Ordinal Baseline)
Here's a list of Sorceress Council Graces, stuff Augustine Did, and Morgiana/Jeanne/Aeslyn's graces for stuff Gisena could plausibly get with Renaissance Halo immediately besides presumably Grace of the Glaze/Evoker's Panopoly/Maiden's Whisper, on the basis Gisena could plausibly have seen them all at one point or another. Also, Renaissance Halo lets her copy say... the Shogun's graces.
1. Porcelain's Invulnerability Grace(White Grace)
2. Porcelain's Water and Energy Grace(Blue Grace)
3. Grace of the Glaze(Would have to sacrifice it to get Renaissance Halo but may be able to use the Halo to get it back)
4. Homing Eyelasers(Kiln Grace)
5. Environmental Animation
6. Essence Draining Resurrection
7. Passive Petrification/Spacetime immobilization defense
8. Intangibility with immunity to detection by conventional senses and mundane physical interaction
9. Battle Precognition(Pennant)
10. Sanguine(Whatever that does precisely)
11. Daystar(Ridable Deathball that can reach at least a 10 mile radius without Grace of the Glaze active?)
12. Embroidered(Personal Outfit animation and weaponization, more outlandish = more powerful)
13. Vanish's Physical Enhancement package(Owned)
14. Vanish's Poison/Disease/Age Resistance(Possibly Owned)
15. Vanish's Orcish mind control grace(Owned if it's Galvanic Truss)
16. Vanish's Luck(Probably not owned)
17. Whatever Enchantress's metapower graces are
18. Abacus's Information Processing
19. Abacus's Phantasmal Weaponry
20. Abacus's Ferrokinesis
21. Whatever Shenanigans Augustine pulled to abduct Verschlengorge.
22. Whatever Augustine did to make the Tower of Earth
23. Possibly Whatever Augustine did to summon a lion from the realm of platonic forms
24. Every Exotic Condition Augustine Tried against Hunger in Fear Itself/The Truth Manifest
25. Phantasmal Servants(The Truth Manifest)
26. Armament Grade Restraint Magic or some appreciable fraction(The Truth manifest)
27. Augustines Protective and Augmentative spells, with the protoplasm flesh technique she uses
28. Infinite Space Defense that Augustine used
29. The analogue to Deathly Star Augustine used
30. Dimensional Separation targeting the Astral Plane.
31. Shade spawning firebolts, the shades last longer in the Orcwaster(Morgiana)
32. Jeanne's maybe a Wits Enhancer
33. Jeanne's Aerokinesis
34. Aselyn's Superheated smoke space warping expanding shroud.
