As I've been rereading the thread for the purposes of my Richer Reality for Hunger, I encountered a couple scenarios around Page
1398. The first being 'If you in the real world could grab an EFB, which one would you pick?' and the second 'You have 20 Arete and 10 Picks, what build would you take, assuming that prereqs based on Artifacts(ie, Thick as Thieves does not require the Forebear's Blade, but Opalescence requires Iridescence) are invalidated?' with it generally being agreed that Kinslayer(4 Picks, set Rank to 5) was pretty much the best pick for Rank builds, unless Uttermost costing you an arm and eye but raising your Rank even more was considered superior, which probably depends on Given how many EFBs and regular old choices we've had since then, how about another go at that? Heck, maybe just go 'Pick an EFB, then build around it with 20 Arete and 10 Picks' this time.
[ ] Hunger - Might's Repose.
[2 picks]
[ ] Feat - Age and Treachery. Gain +.25 Rank. [2 picks]
Evening Sky - Philosopher's Wreath - 7 Arete (2 picks) (Noble Praxis)
Hunger - Stranglethorn (4 picks)
Even though it's an inefficient use of Arete, leaving 11 Arete on the table, this build does everything I really want.
Stranglethorn is a steady, if slow, source of advancement. Might's Repose allows you to live long enough to truly take advantage of Stranglethorn, it also synergizes well with it's strength and constitution boosts by providing you Might over time.
The Philosophers Wreath provides access to a Noble Praxis equivalent that you have encountered, but Feat prerequisites are bypassed for this challenge, so I'll go with the Noble Praxis itself, primarily for it's reliability and because I don't think we've seen anything else comparable.
Age and Treachery provides Rank, which should eventually allow me to, using Stranglethorn, awaken my Rank, thereby gaining access to one of my two favorite magic systems.
I'd start off fairly weak, though Stranglethorn's stat boosts would be quite noticable even for a pleb tier human like me. But given some time and effort I could get quite far. I'd be willing to take on the Geass of Indenture for this, even. Might be worth writing an Omake or two where that happens.
There is a particular synergy between Might's Repose, Stranglethorn, and Linear Halo since Halo scales your Int, Wits, and Wis off your physical stats for the purpose of magic advancement. I tried to find an option that provides a "formal" magic system, but besides replicating Hunger's own Imprisoner soul evocation through the Mage Lord vote I couldn't find a valid vote option. Mage Lord would even have allowed for manual Rank training, which would have been very valuable. The mental contamination from even trying to replicate Hunger's soul didn't seem worth the risk to me.
Superior, but cheesy, variants of this build might try to exchange Age and Treachery for
[ ] Triumphal Gleam [7 Arete] - and
[ ] Breaker of Suns - and / or
[ ] Tower Above -
Triumphal Gleam is already a lot, but Breaker of Suns makes it absurd for such a limited build, +150% Rank gain, much more charisma, +50 to some stats, some extra Rank, etc.
Then Tower Above gets you Rank and a massive discount on a magic advancement, which can even include the Praxis! Since they're both technically a single pick you could easily afford all three. They're hilariously ridiculous, which is why I judged "special advancements" don't count as normal advancements for the sake of this challenge.
EFB wise I have to agree with Wolfy, Once and Future III is king. A full -- limited Royal Praxis equivalent -- custom ontology is just too good.
Edit: the core question, for the build, is whether Soul Evocation counts as a Formal system by default, or whether it is Hunger's particular expression that counts. If the latter then the Librarian would count as well, but as acquiring his evocation is no less cheesy than using Philosophers Wreath to get the Praxis it wouldn't really justify changing my build. If the former though...
