Starting out

• get The Necronomicon , commit it once a turn, scavenge
• upgrade Scroll of Secrets, scavenge it once it's done
• • get's rid of weaknesses, and once Scavenging is out, discarding items from the bottom is basically just drawing them
• Crack the Case -> Drawing Thin
• upgrade magnifying glass so that I can get rid of used Scroll of Secrets and Archaic Glyphs
• get Yaotl, first investigate commiting The Necronomicon, then second investigate use yaotl, so I over-succeed, and scavenge The Necronomicon back to my hand. If Archaic Glyphs or Deciphered Reality is around, get some extra clues. At this point in the game, I can save my skill cards for my friends.
• upgrade Archaic Glyphs

next upgrades

• Plan of Action -> Cryptic Research
• Knowledge is Power can be used with either The Necronomicon or Archaic Glyphs. Definitely discard them for the extra draw, they can just be scavenged in the next action.
• deduction, perception and unexpected courage
• Scavenging is better, saves actions with Scroll of Secrets
• A Test of Will -> Forewarned
• sealing good tokens with Unrelenting, activating Drawing Thin and committing The Necronomicon gives good odds on 3-shroud locations.
• if horror is a problem from deck milling, get Relic Hunter and Cherished Keepsake, combined with Scavenging means horror isn't a problem anymore
