Okay, it needs a new comment, apparently?
Recorded as I played
Ambuscade
Fanatic, Visionary (to try to find Twist the Ether), Sky-Scraper (Incidentally, it's fun watching Ambuscade and his plating beat each other up over Compulsion Canister), Fugue State Parse (Between the Lines was almost as fun for getting radiant damage out of Fanatic as Neural Processing)
Fanatic Cards Played At Least Once: Undaunted, Holy Nova, Prayer of Desperation, Wrathful retribution for 9 points of radiant damage, Absolution, Consecrated Ground, Aegis (though I believe it was said this was NOT played on an unlock), Zealous Offense, Smite the Transgressor, Final Dive was played by Neural Processing but had no available target, Brutal Censure, Divine Focus, Sacrosanct Martyr (played, never used)
I am suddenly not sure whether I played Sanctifying Strike
Environment: Fanatic kills Drudge Ficko with Holy Nova (Damaged by the hunter previously), Fanatic kills Relict Dorotya with Absolution with radiant damage, Consecrated Ground destroyed Feast of Filth/did increased radiant damage to two vampires, Fanatic used Absolution to kill Dame Katarina with Radiant damage, Fanatic used Absolution to kill Blood Countess Bathory with radiant damage, Sky-Scraper used Emergency Evac to remove Hunter Fulepet and Infecting an Heir (deliberately to see if it's just vampire slaughtering, though Infecting could count?), Fanatic used Brutal Censure to kill Matron Erzsi
Fanatic was not the only source of damage to the environment
Divine Focus killed Ambuscade just as the Dowager came out.
No unlock. Never did find Twist the Ether; didn't manage to get the log in time (android)
Next
Ambuscade
Fanatic, Visionary, Fugue State Parse
Fanatic Cards Played At Least Once: Absolution, Aegis, Holy Nova, Divine Sacrifice (killed a Custom Hand-cannon, slapped automated turret), Undaunted, Final Dive (Turret thrown into another turret), Sacrosanct Martyr, Sanctifying Strike, Smite the Transgressor, Brutal Censure, Divine Focus (Was allowed to hit Fanatic at least once), Consecrated Ground (removed charged attacks, damaged Drudge Ficko, Hunter Fulpet, and Ambuscade), Zealous Offense, Consecrated Ground
Absolution mostly did radiant; it was once used to do fire damage once while Unhallowed Halls was out
Aegis saved Fanatic twice, but I don't believe this had anything to do with it.
Environment: Fanatic used Absolution to kill Angry Mob, Unhallowed Halls came into play (destroyed by Parse's Segmentation Fault), Fanatic used Sacrosanct Martyr to kill Blood Countess Bathory(did no damage to fanatic and 3 radiant to Blood Countess, thank you Undaunted!), Fanatic used Holy Nova to kill Dowager Ilona, Parse used Data-Mining to remove Feast of Flesh, Fanatic did the same Sacrosanct Martyr trick to kill Drudge Ficko, Fanatic used Holy Nova to kill Dame Katarina, Fanatic used Consecrated Ground to kill Hunter Fulepet then 11 radiant damage to kill Matron Erzsi and 1 radiant to ambuscade (thank you critical multiplyer), Fanatic used Absolution to killRelict Dorotya
Fanatic killed every vampire once
Fanatic was not the only source of damage to the environment
Visionary was incapped
Game ended with Fanatic doing 26 radiant damage to Ambuscade with Brutal Censure thanks to Parse's Critical Multiplier. This is not in the log (android, I had to grab it just before she played the card)
Unlocked
Thoughts: Fanatic killing all of the vampires, possibly also requiring radiant damage, seems to be a thing, and by extension, the Court of Blood. If it's not just vampire slaughter, I suspect "a lot of radiant damage" (100+?) may be a requirement as well. It could also be destroy 10 targets with radiant/fanatic?
