Honestly, the big, central archive for that kind of crossover is usually Archive of Our Own—AO3. The tagging system is fantastic for finding exactly what you want, and you can filter by 'Rimuru Tempest' and 'Diablo (That Time I Got Reincarnated as a Slime)' pairing, then sort by kudos or bookmarks. You'll get a good mix of the popular, polished stuff there. But I've also had some luck scrolling through niche Discord servers dedicated to Tensei Slime fanfiction; sometimes authors will drop links to their work on Google Docs or personal sites there, especially for more experimental takes on their dynamic. It's a bit more of a hunt, but you can stumble across some real gems that haven't hit the main archives yet. The 'master and devoted servant' trope gets explored in so many ways, from darkly possessive to oddly domestic.
Just remember that 'top-rated' can sometimes mean 'most updated recently' on some forums, which isn't always the same as quality. I've found a few amazing ones with lower hit counts just because they're one-shots or slow burns that take a while to get going. Don't skip past the shorter fics! Some of the best character moments for Diablo worshipping Rimuru are in those tight, focused pieces.

Okay, look, hunting for niche crossovers is basically my hobby at this point. Diablo and 'That Time I Got Reincarnated as a Slime' seems random until you remember Rimuru's whole 'devour and absorb' thing vibes with demonic power progression. Most of the good stuff lives on AO3, filtered for the 'Crossover' tag and then sorted by kudos. You've gotta be patient and sift through the WIPs. Sometimes you get lucky on FanFiction.net if you search the anime category with a 'Diablo' keyword, but quality control is rougher there.
One writer I keep coming back to is 'Aethelstan' on AO3. Their series 'Consuming Eternity' has Rimuru landing in Sanctuary instead of the fantasy world, and the focus on how his skill acquisition clashes with Nephalem lore is genuinely clever. It updates slowly, but each chapter is meaty. Honestly, half the appeal is seeing how authors reconcile the wildly different power scales without making one side a complete joke.

Trying to think of a pattern here, but honestly a lot of the Diablo x Rimuru crossovers I've stumbled on are weirdly fixated on the same thing: power-leveling Rimuru in Sanctuary as some kind of ultimate test of 'Predator'. Like, it's never just 'they meet and chat'. Rimuru gets dropped into Tristram, absorbs a bunch of demons, evolves into something crazy, and then the whole conflict shifts to whether his skills work on the Prime Evils. The appeal is obvious—it's a playground for 'what if' power mechanics.
But the real theme threading through most of these, even the badly written ones, is a clash of world philosophies. Sanctuary is bleak, faith-based, and cyclical with its Eternal Conflict. Rimuru's world in 'That Time I Got Reincarnated as a Slime' is about nation-building, diplomacy, and creating a peaceful monster society. Watching him try to apply those ideals to a world literally built on demonic corruption and human desperation creates a tension you don't get in other crossovers. Does he try to 'fix' Sanctuary? Or does he just become another overwhelming force in the grind? That's the hook, more than the slashy demon fights.

I got curious about this after stumbling across a handful of these crossovers on AO3, and honestly, the 'isekai'd Rimuru ends up in Sanctuary' premise is everywhere. It makes sense—you get to transplant Rimuru's whole 'let's build a nation' shtick into a world that's literally built on cyclical apocalypses. The popular take seems to be Rimuru appearing in Tristram around the events of the first game, trying to apply his peaceful monster-city logic to a place where everything is actively trying to kill you. Writers love pitting his diplomatic skills against the fundamental hopelessness of the Diablo universe.
Lots of fics also explore what would happen if a demon lord's powers from one world interacted with the Prime Evils. Does Rimuru's 'Predator' skill work on Diablo's essence? Can he analyze and replicate Horadric magic? I've seen a few where he becomes an unexpected variable the Angiris Council has to account for, which is a fun angle. The tone varies wildly though; some are crackfics about Rimuru trying to befriend the Butcher, while others get super dark, examining if his capacity for mercy has any place in a setting built on eternal conflict.
Honestly, my favorite ones aren't the power-wank fests, but the quieter stories that focus on the culture clash. Rimuru trying to explain the concept of a hot spring to Deckard Cain, or Veldora and Tyrael having a completely unhinged philosophical debate while everyone else just watches in confusion.

I'm still wrapping my head around these crossovers—how do you even get the Prince of Terror and a slime overlord in the same room? A lot of the fics I've clicked on treat Rimuru's 'Predator' skill like the ultimate power counter. Diablo might throw a continent-shattering hellfire blast, only for Rimuru to just... absorb it, analyze it, and shoot it back with 'Gluttony' turned up to eleven. It turns Diablo's destructive chaos into a resource.
What's more interesting, though, is when writers flip the script on their natures. Rimuru is fundamentally a builder, creating a society in Tempest. Diablo thrives in end-times and despair. I saw one story where Rimuru's ability to name and empower demons accidentally starts stabilizing the Burning Hells, which infuriates Diablo because he finds order utterly boring. The conflict isn't just who punches harder, but whose reality can overwrite the other's.

The whole 'Diablo' and 'Rimuru' mashup looked insane to me at first—demonic hellscapes meeting a cozy slime nation? But after reading a bunch, I noticed the good ones don't just smash the settings together like action figures. They pick a specific point of contact and build from there.
A lot of writers use the concept of dimensional travel or summoning rituals. Diablo gets pulled from the Burning Hells into Tempest Federation territory because of some high-level magic experiment gone wrong, or maybe Rimuru's crew tries to summon a powerful ally and gets a Prime Evil instead. The key is establishing shared rules. Both universes operate on power levels and magic systems, so writers often translate Diablo's infernal energies into demonic magic that the 'That Time I Got Reincarnated as a Slime' world would recognize, maybe as a variant of spiritual or elemental force.
Character interaction is where it gets fun. Diablo meeting a being like Rimuru—who is absurdly powerful yet fundamentally peaceful—creates instant friction. The best fics lean into Diablo's ancient, chaotic nature clashing with Rimuru's modern, diplomatic mind. Does Diablo see Rimuru as a worthy master to serve, or just another being to corrupt? That tension drives the plot way more than just fighting demons.
Honestly, the clunky ones just have Diablo show up and start wrecking things. The smooth blends make the conflict internal to the characters first, letting the worldbuilding follow naturally from their choices.

Straight up, I don't think any major platform has 'exclusive' stories for that crossover specifically. I've been scouring for 'Diablo' x 'That Time I Got Reincarnated as a Slime' fics for ages, and they're scattered like loot drops. Ao3 has the biggest collection by tags, but it's a mixed bag. FanFiction.net might have a few older ones, but the tagging system is a nightmare for crossovers.
Your best chance is to search the crossover tag on Ao3 and maybe check some dedicated Discord servers. Sometimes a writer will post a link to their personal blog or a Google Doc for a WIP they don't want to put on the big sites. I found a really good one once that was only linked in a Tumblr thread about overpowered Rimuru AUs.
