History of Cartomancer

Overview

Cartomancer is a Season of the Witch triumph and one of the ten triumphs of the Haruspex seal: complete all 12 Major Arcana quests from the Lectern of Divination in the H.E.L.M.'s Athenaeum. Each Major Arcana card has its own quest, and finishing it unlocks the card for your Deck of Whispers.

How to complete

1. Collect the Major Arcana cards. They come from The Bladed Path seasonal story quest, hidden collectibles in seasonal locations and random activity drops (Opaque Cards, revealed at the Lectern).
2. Visit the Lectern of Divination to pick up each card's quest, then finish it. Several are week-gated, so the full set could not be done until late in the season.
3. Repeat for all 12. At least 5 Major Arcana cards must be obtained before they can be used in seasonal activities, but the triumph needs all 12 quests.

Notes

This is a past-season triumph; whether the quests remain obtainable depends on the content still being in the game, so check the in-game triumph. The Cartomancer sources describe the requirement but not each quest's steps.
