Introduction
Personal experience of card system. Results from google are a bit outdated because it shows the old card system. For example, OLD SYSTEM: combining 3 normal poring card will give you 1 silver poring card. NEW SYSTEM: The card system has been revamped into combining 5 different cards to get 1 random card of higher rank.
What is cards?
Cards give status boost to a character when equipped. Higher rank cards will give more boost.
How to use cards?
Drag the card into your character window (shortcut key:C) More cards slots are unlocked as you level up.
Where to obtain cards?
Kill monsters and pray hard they drop one. Higher ranks can only be obtained through synthesize. Cards obtainable can be checked in the card album.
Card Ranks. Need to be confirmed
There are 3 ranks in accordance to the color of the card frame. Green (Normal), Blue (Silver), Yellow (Gold), Source: RO2 website. Higher ranks card are obtainable through combining 5 cards of the same rank. However, my first result of combination was not silver rank. Rather it is Normal+. I am speculating that more combinations are required to reach silver...Any kind soul to confirm this?
How to combine cards?(only tested twice and need more confirmation. However, simple steps are provided)
1.Talk to card npc and buy 1 card refine stone from npc. Prepare 5 cards(must be 5 different cards). Talk to npc and select "combine" option. Place 5 cards and stone inside (I don't know what is the extra slot for but I am guessing cash items to boost the success). Press combine and pray hard it is successful as it has 50% of success rate only.
Results from combining cards (Need confirmation as well)
5 different cards combined together to produce a higher ranking card. For example, 5 different normal card = 1 normal+. Apparently, the card obtained is one of cards(higher rank) of the original 5 cards you used. The level of the cards seems to be the average level of all cards used. Different input will affect its result though I don't have enough data on that yet.
How to replace cards?
Just drag a new card over the card you want to replace.
Warning: Old card will be destroyed
