Perhaps even more magical means of chastity like a curse that prevents orgasm or urethral plugs. It might be a bit much though.
I pretty much eventually want to see how interesting the characters get. Rogschard had a ton of character but the UI is very clunky. There is so much potential for that to have parts of it applied to LOH. The dungeon system being one of them. That could be applied later on when the group gains a base.
Actually it's my head canon that this is in the same universe as Rogschard. Just the issue is it could easily be in the past or the future. For example, many of the characters could be relatives of characters from this game.
Aside from that I think that there should be an option to allow our royal dumbass to have their own construct based body that can allow them to help in battle. Of course that would likely require getting him to get a bit more awareness.
On the topic of Mork he's by far one of my favorite parts of this game. When he becomes a party member he should at first refuse to equip or unequip certain clothes. It would make it so you have to earn the right to slut out your party members.
That said, I would give more suggestions, but I would wait until there's a bit more of a good direction of what the game's going to be story wise.
For now, if you're going to have the main end goal to be reclaim the throne, then obviously there would be need for recruitment of different types of people.
A blacksmith.
A mage.
A cartographer.
An informant.
Things like that. Sure, you could have the option to be brazen and get your ass handed to you or you could take your time and build up forces and make a plan. I'm excited to see the next stage of this game. Since, so far, I've seen the forest section as the Prologue. When the game opens up, it'll be really cool to see!
