Basic Card Guide (English)

Introduction
First guide in forum. 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 Results from google are a bit outdated because it shows the old card system.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(usually green card). Higher ranks can be obtained through synthesize and occasionally boss/dungeon drops. Cards obtainable can be checked in the card album. Credits: Flash2k6

Card Ranks. Need to be confirmed

There are 3 ranks in accordance to the color of the card frame. Green (Normal and Normal+), Blue (Silver), Yellow (Gold), Source: RO2 website. Higher ranks card are obtainable through combining 5 cards of the same rank. Read "results from combining cards" for more info.

What is card sets?

Card sets are combination of certain cards equipped in card slots. In return, it will give extra stats boost(read card description).

How to combine cards?(only tested twice and need more confirmation. However, simple steps are provided)

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) Special thanks to Flash2k6, Dztnhy, Hikyuu for helping.

Spoiler

5 different cards combined together to produce a higher ranking. In regards to higher ranking, for example, 5 different normal card = 1 normal+ or 5 different normal card = 1 blue. I don't know how it works but I am guessing that it is random or certain requirements have to be met(level of card). The combination of 5 green cards may result in either normal + or blue.

Apparently, the card obtained from combination is one of the original 5 cards you used. The level of the card produced seems to be the card(used in combination) with the lowest level.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

FAQ : Endgame Raid & PvE (English)

Q: What's the level cap of RO2?
A: As of now, level 50.

Q: What are the things we could do once we reach Level 50?
A: It depends on you. You can farm for items. You can do raids. You can do Khara Quests that you haven't finished yet, etc.

Q: What are Bapho dungeon and Pve Arena?
A: Bapho dungeon and Pve Arena is where you fight boss monsters and get Epic items from them.

Q: Is there a difference between Bapho dungeon and Pve Arena?
A: Yes. The first one would be the boss count., Bapho dungeon only has 4 bosses while Pve Arena has 7 bosses that you need to defeat in order to finish it. The next difference is the item drops, there are Epic equips that doesn't drop on Bapho dungeon but does drop on Pve Arena and vise-versa. The third difference would be is their cooldown, Bapho dungeon and Pve Arena has their own cooldown. Which means if you're on cooldown with Bapho dungeon doesn't mean that your Pve Arena is in cooldown too.

Q: What's the cooldown for Bapho dungeon and Pve Arena for?
A: For example, you're on what we call Cooldown state in Bapho dungeon, you won't be able to get the item that bosses drops. Which means you'll only be able to obtain the items that the boss drops when you're not on cooldown. The same goes for Pve Arena.

Q: When will I be in a Cooldown state?
A: After you kill a boss, the boss that you just killed will be under the cooldown state.

Q: When I'm cooldown, does it mean I won't be able to join Bapho dungeon or Pve Arena parties?
A: No. You can still join the party and participate, BUT you will not able to obtain the items that the boss drops.

Q: Since I won't be able to obtain the item I need, Why should I still join the Bapho dungeon or Pve Arena party?
A: Because there's this thing we called Bapho gold, and Pve Arena gold or Bapho dice, and Pve Arena dice.

Q: What is Bapho/Pve gold and dice is?
A: Bapho/Pve Arena gold means you'll be payed by gold(zeny) if you didn't bid and/or you lost the bid. For example, if someone bids 300z for the item that the boss drops and no one else bids against it, the 300z will be divide to how many players there is in the party minus the player who won the bid.
Bapho/Pve Arena dice means the party members will roll the dice by typing /dice 100. Whoever gets the highest roll will get item.
PS: There are times in Bapho/Pve Arena gold that they will roll the dice. This happens when no one bids for the items that is dropped.

Q: When does the cooldown for Bapho and Pve Arena end?
A: Every Wednesday and Sunday

Q: What does RHM stands for?
A: Random Hard Mode

Q: What is Random Hard Mode?
A: RHM is the same as the Dungeons you went before. The only difference is that it's under hard mode. Which means the monsters has more HP than before.

Q: What do we get from doing RHM?
A: Level 50 Blue equipments, and Old Blue Box.

Q: I wasn't able to finish a RHM dungeon. What will happen to me now?
A: When this happens, you will not be able to enter a Hard mode dungeon that is chosen randomly. You will have to wait for 30 minutes until you Deserteure debuff disappear. But fear not. You can still enter Hard Mode dungeon but you have to enter them Manually.

note: This is for Korean Server. Any difference with SEA maybe only about reset day for Dungeon
