Hand of Fate 2

This Achievement requires you to finish a challenge having equipped one card from your Equipment Deck for each slot. These include Weapon, Shield, Armour, Artefact, Ring and Helm. Curses and Blessings are also shown under inventory but as these are not Equipment they do not count.

This cannot be unlocked until you have gained Equipment for each slot and the last item you will acquire is Artefacts that you unlock in The Lovers Challenge if you go in order. Once you have the required Equipment use Encounters that give equipment and equip an item in each slot, then simply complete the Challenge successfully, optional objective not required, and this will unlock.

This should happen fairly naturally during regular progression of the game if you are using fairly balanced Equipment and Encounter decks.
