12. Celestial Tower (Team) Recommended：★★★★★
Libel II：No. of monster are 5, require to finish the battle in 10 rounds. The main monster will open a shield at the 3rd round, how much DMG received will bounce it back to the attacker, shield maintains for 2 rounds.
Wolf King：No. of monster are 5, main monster will command the attacks. The 1st command is on the wolf on the left to add HP, while 2nd command is on the wolf on the right to attack, blood added will be about 8000.
Fire Elf：It will summon little monsters, max summon of 5. You are required to kill both fire elf and water elf at the same time, or else they will revive each other, both elves can be sealed.
Bane：For this BOSS, you will be required to clear the 2 monsters beside it first (up to a certain HP level will stealth to avoid DMG), or else it will revive the monster
2) Ban：No. of monster are 5, things to take note here is that：the character or pet that the main monster assigned, will attack on the next round (instant kill), can use protection to share DMG, but the dragon turtle opposite will add a protective shield to absorb DMG, hence you can control the dragon turtle first, to avoid increased battle rounds to complete.
Catcher：Main monster will release a group skill to freeze when reached a certain HP level, this skill will maintain for 2-4 rounds, hence the main monster will not die, under the condition of certain DMG killed the 3 monsters in front first.
Zura：Gathered main monster. The main monster will summon 4 eggs; one of them will help our side to add HP, while the other 3 will atta6ck us. The 2nd or 3rd round will have group poison skill and group stun skill released.
Red Horn：When the 2nd king’s HP reduced will fight for the red horn Shield, at that time you can attack the red horn, the king that got the shield will disappear on the next round automatically.
3) Shinra：Here will definitely requires a Cleric to control the opposite sealed monsters in the 1st round, cleaned the Flora monster, Flora monster will basically die at the 4th round, then Cleric will need to control the main monster or else it will revive those death monsters.
Revenge Spirit：Cleric is a must. There will be 5 monsters：Fox、Mouse、Sword Master、Balrog、Mermaid Fairy. When the monsters die there will be 1 revive chance (If the pet have Adv. Exorcism skill, will drive away battle field 100%, Pri. Exorcism skill also can, but with lower probability. Besides that, Trial should works too. (As I don’t have Talisman and a suitable pet to battle, so I never try it before). Fox and Mouse will cause group damage, so it’s better to kill one first, where Cleric control one of them, mermaid heals the monsters, Balrog/Sword Master are single skills.
In conclusion, when your level exceeds the world level, basically to up 1 level will need 3 days, if you want to continue for fast level up, you can consider to bring with a sorcerer and patrol at the monsters scene, the above are the summary of my experiences, hope it can help those players before Lv.65.
