Required Level: 60 and above (which is possible to earn the disk for Calhoun-Violet)
Nick: Max or well upgraded skills
Sulley: Likewise
Calhoun: Equipped with Violet disk.
No matter the difficulty of the City Watch, rhere is indeed a golden setup of breezing through all parts. As of the current updates of the game, your setup consists of three main heroes - Nick, Sulley, Calhoun with Violet disk. Here is the example:
As usual, train three main and two fav heroes to their best. Since there are multiple ways for two remaining slots, I am going to leave this for the players to desirably choose.
For the first few rounds, refill the energy while beating the weak teams down. Do NOT waste them since you are going to encounter more difficult teams.
In the beginning of City Watch, use Nick’s special attack since its increased power is retained until after five rounds. Complement that with Sulley in the following order: Sulley and then Nick (at the same time at the start of the battle).
If Sulley has at most 80% of energy, and you have other strong damage heroes’ energies fully filled, use that with Nick’s attack. Do so before Nick’s crowd of hamsters approach toward the enemies, so Nick gains back energy high up quickly.
Most importantly, make sure your heroes’ energies are well filled before each battle. Once you get used to this, it should take about 10-20 minutes to complete highest difficult City Watch.
Do not forget to switch between heroes if your top team is not capable of keeping important heroes since this can make a difference!
Have fun!
