Lineage II/Coin of Magic

Note: Still a work in progesss!

Getting the Quest
To start this quest off, you must talk to Warehouse Keeper Sorint (Northwest side of Hunter's Village). Once you accept the quest, Sorint will send you to the Union President Bernard (Center of the Hunter's Village between the two bridges) to get the Kaldis Gold Dragon Coin for him. Bernard will tell you that he does not have the coin. After talking to Bernard, you must head southeast to near the Angel Waterfall. You will get the Kaldis Coin after killing a couple of Harit Lizardmen Matriarchs or Harit Lizardmen Shamans. This monster will be around the road just slightly west of the Angel Waterfall. They are also easily found on the peninsula that is surrounded by the river in the Forest of Mirrors. Be careful of this monster. It is level 55 and aggressive. It might be best to get a few friends to help you kill it. You must get the last hit on the monster though to get the coin. Once you have the coin, go back and talk to  Warehouse Keeper Sorint. DO NOT TALK TO UNION PRESIDENT BERNARD WHEN YOU GET THE COIN. He will give you a small amount of adena for the coin and all your work will have been for nothing. Once you talk to Sorint, go through all the talk and you should find yourself a Lever 3 Member of their Coin Collecting Guild. Now you will be able to collect coins which can be exchanged for better coins and then exchange those coins for reward items. To see the list of items you will be able to redeem the coins for, talk to Warehouse Keeper Sorint.

Gambling the Coins
When exchanging coins with the NPCs, there is an option to trade less of your coins to get one of theirs, if you can guess the color of three coins that we will call coins A, B, and C. First you choose how many guesses you will get and the reward if you get it right. Then you guess what color (silver, gold, or blood) each of the three coins are (in order) and the NPC will reply with how many you got correct. You keep doing this until either you get the right combination or you run out of chances. This can only get one coin at a time, though you can only lose as many coins as you bet, not the usual 10-20 coins. Depending on the grade of coin that is being gambled, the ratio changes.

Gambling tips
When gambling, it helps to know what your chances are of getting the guess right. Now, I've made some spreadsheets and tried to figure out if their were any guessing sequences that would allow 90-100% accuracy, and the closest I got was 80-85%, which is good, but you only have a savings of 10% if you get it right every time. In the following info, the letters "S", "G", and "B" stand for Silver, Gold, and Blood respectively (note: I haven't done level 2 gambling yet).

If you were to choose the "4 guesses" option, and then use the sequences SGB, BSG, and BGS (in that order!), then the following match sequences would reduce the possible answers to at most 3. The match sequences are listed as x/y/z, with x being the number of matches in the first attempt, y in the second, and z in the third, and the coin sequences is(are) the answer(s): By my calculations that will give you a 80%+ chance of getting it right every time. If you take off the 4th guess (remove the number for the z guess above), then your chances drop to more like 50% per try (ouch!). If you remove the 3rd guess (by taking off the y guess above), then it drops to around 33% (bigger ouch!). So, unless you are extremely lucky, or just have a ton of coins to burn, I would advise against gambling, since the loss % is greater than the % of coins you could potentially save. I've tried several other guessing sequences (such as SGB. BSG, and then SSS), and none were nearly as accurate as this.
 * 1/1/1 = SSS, GGG, or BBB
 * 0/1/1 = GSS or BSS
 * 1/1/0 = GSB or SBG
 * 1/0/2 = GGS
 * 0/2/0 = GSG
 * 2/0/1 = GGB
 * 0/1/0 = GBG
 * 1/0/0 = GBB
 * 0/0/1 = GBS
 * 1/2/0 = SSG
 * 2/0/2 = SGS
 * 2/1/1 = SGG
 * 2/1/0 = SSB
 * 1/0/1 = SBS
 * 2/0/0 = SBB
 * 3/0/1 = SGB (this will match first try)
 * 0/2/1 = BBG
 * 2/1/2 = BGB
 * 1/2/2 = BGG
 * 0/1/2 = BBS
 * 1/2/1 = BSB
 * 0/3/1 = BSG (this will match second try)
 * 1/0/3 = BGS (this will match third try)
 * 0/2/2 = BSS
