In the early stages of the game, world bosses are fairly balanced to complete and don't take much time and offer some really great loot if you are lucky enough to get something good to drop. That being said, the further and further you get into the game you will notice that these things can take a lifetime to kill at times with fights lasting up to 3 to 5 minutes depending on your DPS or your help. Second longest fights compared to Guild Boss. So start a boss fight and use your excess time to go and grab that cup of coffee you need.

Potential Loot: Master Gear & Weapons, Barrier Crystals, Awakening Jewel, Jewel of Creation, Wing Materials, Equipment Fragments, Holy Water, Pet Evolution Materials, Garnets, Blue Set Treasure Pieces, Exp Orb
