How do you use ritual cards on yu-gi-oh dark duel stories?

Answer 1

Ritual cards are a little confusing in this game. With cards like "Black Magic Ritual" and "Black Luster Ritual" You have to have to have the card that "evolves" into the monster you want and two monsters to offer on the field.

For example: To summon Magican of Black Chaos you need Dark magician on the field (however if you just summoned him to the field, you need to wait a turn before using the ritual).

Then you offer your two monsters and click on Black Magic Ritual, and it will say "used. Dark Magic Ritual. Magician of Black Summoned!" and now the Dark Magician is the Magician of Black Chaos. The same goes for summoning Black Luster Soldier. However this method doesn't work for "Revived Serpent Night Dragon" some reason.
