Put in a random keyword until you find a significantly higher level than yours (use Kite only) and make sure what element it is. Once you reach the server, use Speed Scrolls, Warrior Bloods, etc., and items such as Burning Oil, Well Water, or magics to raise element damage. Use a Hermit Blood on Kite and raise his element damage with an item/magic (whichever element is needed). Encounter an enemy with the opposite element and you will do heavy damage. After you level up, bring your other characters to the stage. You will notice that they also grew in levels by a bit. Use the same strategy (if needed) and raise their level as well.
It is much easier if you have a Wavemaster in your party, whether it is Elk, Wiseman, or someone else; and also have a heavy blade person. This helps very much. Also keep your other members leveled up with you because you have to use them at times. Buy items such as Speed Scroll, Warrior Blood, Hermit Blood, etc. to have a better boosted character.
Have some Wood magic equipped. Start the match, wait until the Goblin runs, then sits still for a moment. Then, use the magic. Goblins are all weak against Wood; two shots will kill them.
