As promised, I will try to keep you all updated on Episode U but it'll be difficult for me to translate everything. So here's my plan, IF new articles don't come in often, I will 3 things from the promised list. =)
Now here's a guide to the fishing system.....
Located at 9:00 of Gludin, there's a NPC that sents players to the fishing zone along with renting fishing rods and selling baits.

There are two different types of rods, a light and heavy time. The light type can be used for close range and able to wheel fast. The heavy type is for long range. Both rods costs 1k for rent fees.
In the fishing zone, players can purchase baits through a NPC. Cost is 57 for 1, 4.6k. for 100.

Procedure to fishing:
1. Position yourself near the lake.
2. Double click on rod
3. Click on the area that you want to fish at.

4. A floating thing will appear, the red is yours and the yellows are other players.
5. When the floater sinks, click on the floater to wheel it in.
6. The item will appear, click F4 to pick it up (others can't pick it up)
Things caught from fishing: small fish, big fish, carp, eel, trout, unique turtle, glowing fish (white, blue, red, green) and a special class of armors filled with water (earrings, ammy, rings, boots, armor, cloak, helmet, gloves and shield)

For the Armors, a NPC will be in the fishing zone for players to repairs the armors for use. As for the fish, the current use is unknown. (maybe cooking)
Update: The set bonus for the armor is total of -10ac, +100HP and +10 Fire Resist. As for the rings are +5mp and +3mp Regen. The Amulet is +10HP and +? HP Regen. The earrings are -1ac.
Player's Comment: Fishing zone is too crowded and the space is too small.
