How things should be:
There needs to be a clear and consistent message on whether the Patron perk still applies and if the patch is accepted by the IRC community.
Characters should be able to serve one, two, or zero patrons (including Puchuu).
It should be clear how the Puchuu doc interacts with the Patron doc.
Patron mechanical benefits should be roughly balanced.


How things are with just the Patron doc:
The number of additional benefits and drawbacks is tied to your patron, which obviously assumes that you have just one.
The only Patrons with mechanical benefits are Deities and Beacon. Deities gives an absurd +1 to STR, AGI, and VIT, and Beacon gives +1 LCK via Fake Parents.
Some Universal Benefits are fantastic (stat gains, Mystic Artifact), others are unspecific (Mana Font) and others are just fluff.


How things are with the Puchuu doc added to the mix:
Puchuu girls get a random stat bonus via Motivation. They also get some highly variable value out of the Puchuu perks and powers, assuming their Puchuu accompanies them.
What's the most a Mahou could get from their Puchuu? Probably +1 to a key stat; +1 to a spec stat, +1 to a single defense roll, teleportation (out of combat) while with your Puchuu.
Interaction with the Patron doc is completely unclear. Do we add all the benefits and drawbacks together? If I rolled Isolated on the Puchuu doc, should I take it on the Patron doc?


Now let's tack on a Patron patch:
Patron perk is removed! Except it's actually not removed in the PDFs and nobody likes Rival anyways. Instead we all get to live with ambiguity here.
Lesser Forces get an irrelevant buff. Deities still OP. Beacon gets nerfed because Fake Parents is too good :^)
All of the Universal Benefits with mechanical benefits are removed, then a new one gets added


O-okay, now Sanctification rules:
Overwrites Patron doc benefits, but the Patron benefits are mostly just story-related. On the other hand it doesn't replace the Puchuu doc, which does provide several mechanical benefits.
MAG characters get a sweet +2 bonus to their specialization spells against corrupted targets. Other stat builds can just die for all we care.
You're forced to defend against magic used by corrupted beings. That's cool and makes sense, unless you have Third Eye and know what their spell does.
Stat bonuses informally removed from the perks.
It's not really obvious whether people who "Embrace the spark!" also get the "Just a little" benefits. Presumably yes.
As it is, Sanctification is just a bit better than having a Puchuu from the Puchuu doc.
