1. Delivery quest:
The Ivy Quest begins in Sarmakand with the HunterGuild. From there must take a horse and ride to Constantinopel and deliver the letter to Ratchel, who stands south of the Stable deliver at the MilitaryCamp.
2. Ivy 1
Recommended level: 25
Now you Talk to the SAME NPC where you delivered the Quest before. here
You need 20 Vine stacks. You get these from killing Soldiers at Haran's Tower. You need approximately 45 Small Knifes that are droped Only by the soldiers. To turn these into vines you need to run to The Pond Ruins Because it only works disjointing here. You can disjoint these like you did with the Charms at the Taoist Quest (right-click on the Items). If you do not get 20 Vines Stalker, must you go back and kill more soldiers for more Small Knifes.(Traps).
Go to this guy and do this quest to gain 5 traps as reward
3. Ivy 1
Recommended level: 30
Now With the traps you got from the helper quest, find the Closier informants that are infront of the Amphietheater. Right click a trap so it's layed on the ground (red kind of net thing) you need to lure an Informant into the trap, easiest way is to PUNCH it (without weapon) then run over your trap so it follows you. When you have one Closier informant imprisoned, run to Constantinopel within 30 minutes. Running, not riding on horse or transport because: On the way Closier Guardians spawn. You must kill 15. They spawn approximately every 60 seconds. After the 15 are killed, run into the city and deliver the Quest.
4. Ivy 2
- at least. Lv.35
- EXP/Item Party Share with at least 2 Members in party (Leader and a friend)
- Party Leader must have Quest Ivy 2
Talk with that NPC south of the Stables to get Ivy 2. You get 5 horns when you accept. Now, you use these horns @ Harans Tower, Cleopatra gate and Amphietheater. There you must activate at certain places (usually at the entrances, shown on SS's where you must stand) a horn and the monster that spawns, you have to kill. Each monster will drop for each Partymember in the proximity an Item, however only the Leader needs the Item. When the leader has all Items of the monsters of the 3 places(3 stones) then you kill Punishers at the Amphitheater untill it drops Punisher Blood
When you get a Punnisher's Blood, right click it and all 3 stones will become a Key. With this Key you travel to Evil Fortress into the center of the 'Den'. When you stand here, all other party memebrs must be away from you so their faces are 100% blue on the party bar. You now right click the key and Captain Ivy will spawn after short time in your proximity. Within 20min must you it kill. After kill you get a Hair. As soon as you kill her and get item, teleport , go to Constantinopel and deliver the Quest.
With successful Quest you get 20 Scrolls, which load your Berserk immediately when it's empty
