That is true, but it's supposed to be hundreds of times easier. For some unknown reason, after releasing chapter 3, the slime queen fight is nearly impossible because the player doesn't earn two specific skills related to vore. One that gives you health and another that lowers enemy stats.
With these it would be a cakewalk but now, unlike cases like yours, it is nearly impossible.
I have tried to replicate and find a solution myself but my game runs perfectly fine without any problems at all so I have no idea why all of yours doesn't.
I don't wish to sound like a know it all. Let alone tell you how to make your game. So most certainly, take what I say with a grain of salt.
To also clarify. I did get the skills after rebooting my Save. I'm not sure if I did anything different to explicitly earn the skills this time around. I lvl'd up in both of my Saves. Just this time around, I got the skills and the first time I played. The skills failed to show up.
Anyway. The main reason that boss is difficult. Isn't because of skills or lack thereof. It is as I was saying, because the enemy is very close to the Hero's level in...basically everything. So, it basically becomes a fight of back and forth slapping. Until the other mobs come in and you have to change up your strategy of spamming the attack button.
It's not as if the skills themselves are bad. I can see how useful they would be. They just aren't useful for that boss specifically. The healing skill is better at maintaining your Hp at a certain point. Rather than outright healing you.
(Quite literally I think, at most, I healed about 5 whole Hp. If the boss didn't guard and so I got to heal a full 40+ Hp. Boss does about 40 dmg, the healing skill does about 40+ healing. So yeah. Not exactly a healing skill in this fight particularly.)
The debuffing/attack skill is also just not useful. Mainly because it only applies those debuffs to an 'immobile enemy' who is already taking dmg each turn. It also feels rather pointless, in my case specifically, as the enemies rarely escape the stomach. I can't vouch for others. But obviously, if I feel as if an enemy is just slowly dying and incapable of hurting me. With basically no chance of escaping. I don't see much of a reason to use that particular skill.
It becomes an uphill battle however. If you don't go into the fight with the full stat boosts, you gained from the 2 previous fights. Even losing 1 stage of weight makes it feel way more challenging. I also believe it's because this fight has just 1 hero. In classic RPG's you have the team and a dream. The tank, the attacker and of course, the healer. Everyone has their role and an action to do their assigned tasks. In this case, you have 1 person juggling all of those roles. Which is a challenge in of itself. Having to question every action you make. "Do I heal? Should I guard? Can I get away with an attack?" This is what it felt like when going through the fight. Especially throughout chapter 3 as most of those fights were also solo and quite difficult.
So, to sum it all up. The main and true reason why this fight is particularly hard. (In my opinion, which you can fully disregard.) Is because of the chance that you lose the boosted stats. Take a little too long in exploring the dream. And you basically throw away your chance at winning that fight, let alone with ease. The skills themselves don't particularly help or worsen the fight. It's more about the fact that you're fighting alone. And Juliana isn't exactly the more capable fighter of her current team. I barely used the skills even when I had acquired them. And still had a relatively easy time with the fight. Its main difficulty arrives at the very end of it. When the boss is at 150-170 hp and summons 2 mobs. That's an extra 40 or so dmg Juliana is getting hit by. And if your Hp is relatively close to the boss's at that point in time. Well, that's not exactly ideal. And since your 'main source of healing' does a better job of just keeping you alive. You're more likely to be the same Hp as the boss.
That's why I recommended giving players a medium potion, if anything. Using that so they can easily tank 2-3 turns of attacks. Nom 1 of the enemies. Finish off the boss. And casually defeat the other mob.
But it is your game and I trust your judgment with it. I'm merely another of the voices that is speaking their mind.
Damn, that's a lot of words. Too bad I'm not reading them B-)
Nah, just kidding, I read it all and I see your concerns.
My main idea for that fight was for you to see how you can both vore and fight at the same time and how they could coexist.
Enemies do actually damage you from inside after being nommed and can escape if too much damage is dealt to the player. So if the damage debuff and the defence debuff works well both for taking less damage whie they're inside and to deal extra damage if they so escape.
Either way, I see your point and I can also fix it with one simple tweak:
Lowering the Slime Queens stats :)
I honestly don't like what I did with the potions as they're supposed to be last minute items you need to reserve for special situations, but I had to put them almost everywhere just to make the players survive.
So, I see your point of view but to not make the player frustrated and think it is too hard since they *had* to use a potion, I'll simply lower the slime's stats instead. That should hopefully even out the slap-match you had been going through lol
But that will be after i return home, as I am currently talking through my 6 year old laptop XD
