Hello everyone, welcome to my guide!  In this guide you will find everything you need to get achievements, special events, endings and more in Arkham – The Dark Legacy.  Please do head over to for more great games such as this one and support them!

The following guide contains themes and characters that belong to Lesson of Passion.  This guide is fan-made and was created out of respect and for recreational fun.

This is a free guide; if you have paid a site and were redirected to this page, ask for your money back, it is a scam.

Rules (RLE)
Charles Ward, an investigative reporter for the city’s newspaper who happens to be head over heels for Asenath, a shop owner who sells curiosities and witch craft materials. After “dating” with her, she moves in with him and they soon find out that Charles is a descendant of Joseph Curwen, an evil sorcerer who was killed years back. As Charles tries to get his life to move forward, he’s haunted by Curwen and now wants to investigate his ancestors past in hopes to have a better future.

Arkham – The Dark Legacy is an erotic adventure game where the player takes control of Charles and wanders around the town of Arkham trying to piece together his family legacy and resolve the supernatural circumstances that surrounds him. Study the dark arts as well as human science, investigate strange and ominous places that are hidden in this infamous town. Take your time exploring and discovering with unlimited days and no limit except for your sanity. Welcome to Arkham!

SCIENCE: Not all beakers and flasks, but close enough. Your SCIENCE stat helps with understanding of the human arts and create things with it.
OCCULT: In Arkham, it’s never that simple to chalk everything up to science. Your OCCULT stat is your level of understanding in the mystic arts and you can wield them.
SANITY: Arkham is not for everyone especially ones with fragile minds. Your SANITY is like your morale, but here if it hits zero, you’ll go insane!

You will have an option to either save Aseneth (50 Occult) or leave her to die (where she will never come back again). Afterwards you will unlock Hannah’s third level and a sex scene with her. And if Aseneth is alive, a scene will trigger with her later and you will unlock her fourth level with her too.
-If completed “Elixer of Life” event and you go home when Asenath is the attic, you will go with Asenath. You can either fight Asa (if you know the Elder Sign) or let Asenath fight Asa (Asa will die). Either way you get Curwen’s saltes. You can now summon Curwen in your attic.

Elixir of Life (Unlocks after “Grave Robber” event and summoning the witch)

  • JimMorrisonIsAlive1969 says:

    What does it take to get Hannah to agree to participate in the Ultimate Ritual? She is at 180 points. I created the Inhibition potion to motivate her. The other two have agreed. I am waiting on her.

    • LOP_Daman says:


      Trying to remember. I think you need to go to get the evidence against Asa and when you need to go over to the farm, go with Hannah. If you don’t do this, I think you will get her to the fourth level that you need to ask her for the ritual.

      • JimMorrisonIsAlive1969 says:

        I know I did all those things except getting the evidence against Asa. That’s probably where I failed. Thanks

      • JimMorrisonIsAlive1969 says:

        My mistake was that I had taken a shortcut and killed Albert rather than take the effort to control his mind, so I didn’t gain the evidence against Asa. I did it right today and Hannah participated.

  • obsexo says:

    Im trying to get the Ultimate Ritual, but Elizabeth keep rejecting, I have her in more of 200 of relation. I must go past to final showdown, defeat Curwen and return?

    • LOP_Daman says:


      It’s been a while since I last players this title, so I’m not 100% certain. But I think once all the major story elements (like the ones you listed before) are played out, can you then find the harem style ending.

  • zmanzman says:

    Just wondering if anyone has played recently and been able to get the “Summoner” achievement. I followed directions in the walkthrough and it didn’t pop. Summoned wealth, witch, scholar, and seductress and no “pop.”

    Everything else works fine.

  • zmanzman says:

    Yep, that worked. Thanks Daman!
