“Friendship Level” describes just how well you get on with NPC’s.
Each individual NPC has their own “Friendship Level”.
“Friendship Level” is shown by the number of starts above an NPC avatar’s head.
Please note that there is a maximum limit to “Friendship Level”.Once this is reached, the level will no longer increase no matter how many further duels you play.
* If you are given a “Deck Recipe”, please note that you will not get the cards that make it up.
A “Deck Recipe” Yoy got from NPC is a “Structured Deck” entry that tells you what cards are needed to build a certain themed deck.
When you are given a “Deck Recipe” you will not automatically get the cards that make it up.
If you don’t have the cards that are needed to recreate the deck, they will be listed under “Cards Missing”. Some recipes may also included certain cards that may be forbidden or restricted by the rules, so it is up to you to adapt the recipe to suit.
