If you want to beat the Kraken on NMHC. Best to just solo him. This keeps him from running all over and smashing towers. I use my Barb and just circle him, or use Huntress and turn invisible. Kraken can't see invisible Huntress.
If you have a team, you need someone with a block weapon and powerful sea horse. Just have the person block, the rest wail away. Only found a team once to coordinate that though. Most are not prepared.
For spider Queen. Just dump traps, archers where she lands. That normally keeps her in place, then hack away.
Marrago, you just have to get good at finding those lamps.
Sky City boss on NMHC is sort of like those side scrolling games where you memorize jumping patterns. Once you figure out where to get on the ship, where to jump off, what to dodge, have heal aura ready, the boss is really easy.
the trick is to have enough DPS to make his Alarm sound every time before the ship rounds the corners of the building. I only have two characters that can do that. Playing Solo helps as it shortens the amount of damage before Alarm sounds.
you remember no dmg tower, archers are kind in my opinion. I am just messing around with self set rules because i have beaten the game like a month ago month . And solo the kraken without a pet? I posted that i want to beat every map with half the du no dmg towers and no pet sorry for miss info i thought posting my stats would make it so people would know i was at the end game :/.
