The Mountain Titan is a quest you should do EVERY DAY! It gives 20,000 experience points as well as 10,000 copper for the level 20 Titan. The Mountain Titan has various quests depending on your character's level. These quests are for level 20, 30, and 55.
HOW TO KILL THE MOUNTAIN TITAN...
The Mountain Titan has a Left Hand, Head, and Right Hand. Each of these are a separate target!
Begin by focusing on one hand, moving on to the next hand and finish with targeting the Titan's head! It is a very straight forward fight.
If you are too weak to do any damage or get hurt, then just DEFEND. During Titan 20, it is common for the lower levels to rely on one or two people to kill the monster. If you DIE, DO NOT LEAVE! You can still get credit for your groups kill if you are dead!
Tell your team mates the target order! If you focus fire, your fight against the Mountain Titan will go much better for the entire team!
