The eternal Blue Planet 51-55 strategy

Inventory of Monsters

Electromagnetic mecha: Meat shield monster, when damaged by mage, the 50% probability of expanding the shield with a maximum health value of 40%, and the damage caused by warriors and summons is increased by 20%.

Goblin Priest: Every once in a while, the skills will be released to restore the lives of the surrounding monsters. The damage caused by shooter and poison is increased by 20%, and the damage caused by immune mage is increased by 60%.

Light-proof Goblin: Goblin with lightning rod is immune to 60% of the mage damage and cannot be paralyzed by lightning.

Evil Priest: An evil priest who is proficient in witchcraft can restore life to nearby monsters, and receive 20% damage from shooters, warriors, and poison. Can't be knocked back, can't be continuously controlled.

Level Gain

The gain BUFF of levels 51-55 is the final damage increase of [Shooter] and [Warrior]. Make reasonable use of the level gain to easily increase output.

Perfection skills

Swordsman professional heroes can get 51 and 52 levels to control the "Goblin Priest" and the "Evil Priest" of the BOSS.

The explosion output of the warrior profession also restrains the recovery monster and the meat shield monster "electromagnetic mecha". With the exclusive buff BUFF of level 55, it is like a tiger's wings.

After the River Manager is upgraded to level 15, it will unlock [Reduce the Healing] Passive: The monster damaged by the River Manager is reduced to its healing effect.

Anne can also obtain the [Reduced Healing] effect after unlocking [Raging Fire]-[Ghost Fire Burning].

Advantages: Strengthen the entry without rating requirements; disadvantages: relatively high randomness.

After the Black Lily reaches level 20, the damage to the monster will be reduced by 75% of its healing amount. The level requirements are high, and there is no need to pay too much attention.

Linework Recommendation

This recommended lineup consists of [Iron Wang, Sword Saint, River Shopkeeper, Anne]. If the steel dove has not been unlocked, you can use a rocket instead.

The output core of the lineup is Iron Wolf and Sword Saint. While having high output, the two heroes have faster attack frequency and have a low dependence on attack speed auxiliary gains.

The combination of Iron Wolf and Sword Saint: The attack range is complementary to each other, and the output form takes into account both AOE and explosion, and can deal with more types of monsters.

The River shopkeeper asked to upgrade to level 15 to add the effect of reducing healing to the monster. If you have not reached this level, it is recommended to go to the position of Gopher, Xue Ji and other control heroes.

As one of the panacea professions, Anne has no monsters to restrain summoning objects this time, and she can fully utilize the functions of summoning bears to mock monster gathering, knockback, burn and reduce the healing.

Totem recommendation

Considering that the hero's exclusive totem is rare, it is recommended that you keep the refining stones for the entry of the peerless heroes, and there is no need to specifically refine the legendary hero totem.

Totem Effect Bonus>High-quality Totem Attack Power Bonus. If you have ready-made totems of Iron Pole and Sword Saint, you don’t need to care about the quality of the totem and just equip them directly.

There are fewer types of monsters that are difficult to deal with this time, only "Meat Shield Monster-Electromagnetic Mecha". According to your output to the BOSS, you can independently select the corresponding monster damage-enhancing totem.

Entity recommendation

Taking the recommended lineup as an example, the priority of the hero strengthening entry: Iron Wang, Sword Saint>Anne>Hezhanggull.

Iron Wang

Iron Wang added a "weakened grenade stream" in the last update. Select [Ray Grenade] to enhance the entry. Killing monsters will leave grenades to release weak rays, which can deepen the damage of monsters. This genre can be played and assisted!

Sword Saint

Defending evil priests not only requires reducing healing, but also explosive output is also important. It is recommended that the Sword Saint go to [Critical Fencing Qi Stream] to increase the output and quantity of sword energy, and deal high burst damage to the BOSS.

Anne, Heshangguan

In this lineup, Anne and Hezhangguan are not output. Priority is given to unlocking Anne’s [Armored Giant Bear] ultimate move to protect the city wall, while the Hezhangguin’s ultimate move plays a role in increasing the coverage of [Reduced Healing], with a lower priority.

The four heroes in this lineup all have good output at the beginning. It is not recommended to synthesize and improve the stars too early. You can first take the full heroes and accumulate certain silver coin resources before upgrading the stars. Priority is given to using Heshangguard and Annie to synthesize the stars, with the goal of synthesizing high-star swordsman and a large number of steel wolves (2/4 stars’ best), and keep 1-2 Heshangguard and Annie on the field.
