Hidden Helper T quests

Hidden Helper T Quests are quests available in "Normal Quest" tree on the "Quest List" panel. There is a total of 81 auests available, numbered 001 to 049 and 051 to 082.

There are certain requirements for each of the quests to be met before acquiring them. Each quest has certain character level requirement and character class rank requirement (achieved upon completion of growth level quest). Without the class rank met - the quest will not appear on the available quest list in game. As an example - the first quest requires character level 36 and character class 3, so a level 45 character, with character class rank 2 will have no access to it.

This list consists of quest number, character level requirement, indication whether the quest is a Kill task or a Message Gathering task, amount of monsters to kill or messages to get, target monster's name, location where the monsters are located, and of course rewards for completing each the quest.

Dungeon Training Card quests
There are 12 additional "Dungeon Training" quests which require a D.T. Card in your character's inventory for the quest to appear. If you have a card in your inventory, for which you have not yet completed Hidden Helper T Quest, re-log with the DT Card in inventory or move to warp zone or another town and the quest should appear.
