90% des énigmes dans le jeu sont très faciles à résoudre, soit la réponse est dans la salle, soit elle est sur la clé, soit elle est sur une note/un livre trouvé dans les environs.
Pour les mines et les endroits pour récolter les différents minéraux, j'ai une liste mais pas avec moi (je suis au taff), je la posterai quand j'arriverai chez moi

Et sinon, yen a qui ont testé le glitch pour se faire de l'argent à l'infini? J'ai testé celui de Sightless Pit, j'ai dû me faire environ 5000 en 1 voyage avec un compagnon, je vais peut-être le refaire éventuellement mais pour l'instant je trouve que ça un peu trop long et répétitif
