How to Enter Costlemark Tower

To effectively get into Costlemark Tower effortlessly, you have to begin your quest at nighttime. It is only during that time where you will be able to see and locate the passageway to Costlemark Tower which is invisible during the day.

Level and Items Required To Costlemark Tower

Reach level 55 of the game or higher -- it is the safest level to embark in the Costlemark Tower game. It s also filled with demons, making it one of the most difficult dungeons to conquer. Furthermore, bring a lot of healing items including items and abilities that will battle the petrify effect. In the boss battle, the ultimate boss will use tons of it against you and your team. Bring at least five magic flasks, extra Fire, and Blizzard for the final boss fight.

Monsters and Their Weaknesses in Costlemark Tower

Costlemark Tower is home to a variety of unbelievably powerful enemies, mostly demons. Some do not have a particular weakness. For magic, typically you should be hitting 9999 at the moment so that a direct weakness isn't always necessary.

Gelatin's, Level 35, weaknesses are Royal Arms and Lightning while you can easily take down Thunder Bomb using swords. Another monster, Galvanade at Level 54, is weak against Guns, machine Weapons, Blizzard and Royal Arms, according to IGN. If you take too long to kill these, they bid lots of Thunder Bombs. Dawn Hammer is best to take them down quick. Furthermore, Ereshkigal at Level 39 is weak against Swords, Royal Arms and Fire.

Final Boss Fight in Costlemark Tower

Jabberwock at Level 58 is the final boss to combat. This is essentially a straightforward fight. Keep your distance from him and unload with Techniques and Blizzard spells. He has an AoE Petrify that is almost impossible to dodge so bring items with immunity if possible, says GamersHeroes.
