This mission is fairly easy, just make sure you have MANY HP pots with you or a Cleric/Priest/Bishop in your party to mass heal. You will also need to have a LOT of patience since this is a JUMP QUEST!
I know, most people hate jump quests, as do I, and this one has 2 screens of it that you need to get through to get the next piece of the Quest in order to get to the 3rd Mission. If possible, use a gamepad/joystick to try and finish the quest, since using a keyboard might not give you the right timing to get through the quest. If you are a PRO at using your arrow buttons and jumping using your keyboard, then you're a better Mapler than I am.
Once you get to the end and talk to Lira (NPC), you will be granted The Breath of Lava. This is an important second piece of the quest items you will need in order to get the last piece of the puzzle. When you exit this map, you will receive 12,000 EXPerience for completing the mission.
Good luck with this jump quest!
