Revenge of the Fallen: The Riverborn (Riverside Refuge Preview)

Hi all! I’m Foucs, the designer guilty of spriting Asgard, the Gelatinous Palace, and a bunch of other stuff. Weekly devlogs are a pain joy for the team to write, and it looks like I’ll be your host for today. In this blog post, we’ll show off the Riverside Refuge biome, inspired by the original Riverborn event from legacy RotF.

welcome to the refuge.

The Refuge biome itself is a thick swamp, filled with frogs, tree bugs, and other ⭐ m a g i c ⭐ inhabitants. Everybody knows that frogs are a staple of good biome design. More frogs means better game (obviously). Take a look at these friendly froggy foes:

Now, I know what you’re thinking: those frogs will be really lonely without some friends. We agree, imaginary reader! While navigating the marshes, you might stumble upon a fascinating creature, an impostor (āļž) of sorts. These are the River Striders and Lurkers, also known as the Living Brushes.

Next up, the River Serpent, aka Flying Snake Boyo. His bubbles are tricky, so watch your toes.

What else might you find in a magical swamp? The giant water-dragon-snake-beast with a hunger for humans, of course! For the first time since legacy, meet the Riverborn, Lord of the Refuge.

what a beauty

Like other Lords in RotF, to challenge the Riverborn, players will explore the realm, and search for his home waters. This Lord has some tricks up his sleeves (…wings?), so approach cautiously! While you’re slowly wading through the water, the Riverborn unleashes torrents of wind.

In addition to spawning watery disasters at will, the Riverborn possesses another innate skill: diving. Watch as he plunges underwater, stalks players while submerged, before popping back up (and popping your health bar too).

In this section, I’m supposed to talk about what I worked on in more detail, but I’m sort of already out of ideas. So… let’s plug socials! BQ and I both stream on twitch (at and respectively). Come on over, and tell us why the frog to regular enemy ratio should be 1:0. We’ll agree.

We’re excited to show more stuff from the Medium-rank areas, so keep your eyes peeled! As always, we’ll update this post in 15 minutes with some CT keys. Lastly, a big shoutout to the RotF community for staying chill and supportive. You guys rock. And the most important thing: this post has a frog rating of two 🐸

We’ve got another CT key puzzle, brought to you by Skilly. Check it out here.

Use at Good luck!

Revenge of the Fallen: A very magical hideout

Hi all, and welcome to the first of our new weekly dev logs here @ This time, it will be I – patpot – showcasing some new content for you all.

Although we know you want to see the harder, late game content we’ve been working on, we’ve chosen to showcase the Magician’s Hideout (another early-game area). We need to do a bit more work on late-game character building before we’re ready to show those harder worlds, and since early-mid-game content will be much more expansive than in legacy rotf, we decided to show more of that, for now.

As mentioned in my previous content post, every biome/dungeon is intended to feel like a unique experience, each with completely unique enemies, distinct dungeon themes, and crazy boss fights. Despite being an early-game dungeon, the Magician’s Hideout is no different.

One area we wanted to focus on as we moved forward from legacy rotf was developing more interesting shot patterns (like those used in our favorite bullet hells, i.e. ETG). While our overall design philosophies have evolved and improved across the board, we’ve also developed new systems/mechanics to help us keep baddie engagements fresh. One such system that I built out: patterned enemy shots, which allow us to create effects like this:

Don’t stand too close!

And while it has been cool to use this mechanic on smaller minions like these, we’re also using it to add flavor on a larger scale, like in boss fights:

I wouldn’t touch that barrier if I were you, I heard it moves!

For those of you keen enough to notice the (very, very) placeholder dialogue in the clip above, what you just saw was the Master Magician – the lord of the biome. A few days ago, we posted a spoiler in our Discord of a fancy-shmancy magician’s hat, simply lying on some grass. As made evident by the clips above, that hat is the entrance to the Magician’s Hideout! Each biome has a lord, which drops a portal to its respective dungeon. Here’s a small peek at what you can expect from this one:

It looks dark in that hat, hopefully there’s a spell in that book to light it up, there’s definitely one to light you up.

For those of you fortunate enough to survive the hat (easy dungeon btw), you’ll be greeted with a friendly portal to the larger part of the dungeon. Teleport animations return from legacy rotf (thanks to Bloodqwen for making the amazing animation and to Miniguy for building the system that powers it), allowing you to escape the magician’s hat with style.


We saved a lot of juice for the boss area. To reach the boss, expect to herd rabbits and admire Quaximi’s 3D designing skills. There are definitely worse ways to die in a dungeon.

No rabbits were harmed in the making of this video, they were transported to a better place.
You can almost hear the nostalgic *click* of a gate opening.

Oooh, a cliffhanger. You hate to see it! I guess that boss fight will be waiting for you to experience first-hand :).


See you next week!
