Do I need to grind a lot to beat the tower bosses?

[Kersakof]

Just got to the desert one, they're 150k hp and I'm in pal metal armor with level 40+ pals. I barely made a dent into their HP, granted some moves just didn't hit because the pals kept shooting the ground. I know the HP goes up after this one, so I'm wondering how much I have to invest into the stars and pal souls just to be able to beat every tower boss.

i didnt have any stars nor pal souls invested for my bosses.
i also didnt invest in attack on myself.

i would use pal metal armor, and rocket launcher.

i was max level though, and i did have legendary pals.

so at the bare minimum youll probably need to wait for max level to take on the last 2.
make sure you have a pal with strong moves, and try to go for the elemental advantage.

i believe the snow biome boss is dark type so weak to dragon. the desert is fire type so weak to water, and the volcano electric type so weak to earth

for 4 out of 5 towers you can do fine playing the normal progression but the last tower is either too overtuned or barely manageable if you know how to fight them

Pretty much like Darth I didn't have stars or souls invested or attack on myself.

Had the best armor and I didn't have the rocket launcher but instead had the legendary pistol and used the assault rifle. I also had 1 legendary pal but swapped here and there to others and that was for the second last tower, the final tower I had 3 legendary pals and just had the legendary assault rifle.

The pistol I got lucky on the first capture but the assault rifle took me a lot to grind, could of gone for the rocket launcher but I purposely avoided it. Just need to see what you're up against element wise then counter it and you'll be good.

for the last two (desert/ice island) you gonna need legendaries. a whole team of those. they hit like a truck and their defense is enormous. i am max capped with a frostallion in my team and i still cannot beat the last two ones. even for the volcano one i do recommend having at least one legendary in your team to make it smoother. (go for frostallion, it helps on that particular boss fight).

also, don't do like i did and forget to have a shield. it is asking for the boss to steamroll you. it is non-negotiable that you gotta have a shield to even think on facing them.

imo, they are ballanced for Multiplayer, even on Singleplayer servers. would be good imo, if we got a togglebox to ballance them for singleplayer or have the game do it automatically for us. maybe in another update i guess?!

Damn, that's what I'm missing? I was using rare pokemon I got from the 3rd island nature reserve and they weren't enough. Suppose I'll lean harder into a full team that counters the boss.

max level, rocket launcher, frostallion and jetragon. get used to switching pals so they dont idle whilst waiting for ability cooldowns or eat attacks

[Big Isaac]

The rocket Launcher really shines during Boss fights Imo Large chunk of damage then run and hide. Takes some time to make the ammo but once u got it going Everything gets a little easier.

It's like Elden Ring with Pokemon's theme.

I honestly enjoyed the breeding and difficulty of legendaries but didn't enjoyed the grind for the last two towers so I changed the settings for damage done and others to do it.
I also don't like that there are timers..doesn't make sense to me.
Imo they are overtuned and that's fine in an EA state so I didn't mind changing settings to my liking :)
