Nothing pure grows in Romeo Is a Dead Man’s soil. Behind its rusted barns and chipper chores, the farming-sim hides a cruel hierarchy-one where blood, lies, and inheritance matter more than any harvest.

How to obtain Bastard seeds in Romeo Is a Dead Man

You’ll need to forage in the fields and interact with the game’s seed merchants to obtain Bastard seeds; gather enough currency and complete a quick quest to unlock the seed slot, then plant them in fertile soil to begin your hybrid farming path.

Romeo Is a Dead Man includes a farming-sim minigame, but instead of growing cauliflower, you’ll be growing Bastards. If you don’t have one yet, continue playing until you obtain your first Bastard seed. This will likely happen at the beginning of Chapter 2.

One Bastard seed is enough to start farming, but as you progress through the game, here’s how to get more Bastard seeds:

  • Defeat enemies: Their chances of dropping Bastard seeds will increase in later Chapters.
  • Loot Tesseracts: Although they usually contain Sentrey, consumables, and ingredients to cook katsu curries, they’ll occasionally give you a Bastard seed. One such Tesseract is found on the upper floor of the mall in the hall between the red portals (Chapter 2).
  • Buy them from Siroyabu’s shop: Common, rare, and epic Bastard seeds cost 500, 1,000, and 15,000 Emerald Flowsion, respectively.

Don’t worry too much about Bastard seeds, as you’ll get plenty in later chapters. It’s best to refrain from buying any unless you’ve got Emerald Flowsion aplenty.

Once you’ve got some Bastard seeds, bring them to Romeo’s sister, Luna, for appraisal. She’s in the Bastard harvesting room aboard the Last Night spaceship (the room marked with a plant icon).

Following the appraisal, you can plant your Bastard seeds in the two garden plots. They need 10 minutes to mature, but you can speed up the process using Emerald Flowsion or harvest them earlier, in which case they’ll suffer a stat penalty. You can also use your Emerald Flowsion to buy more garden plots.

However, if you’d like to save Emerald Flowsion for other purposes, it’s best to go on missions and frequently use a Space-Time Pharmacy to teleport to the Last Night, harvest your Bastards, and plant new ones. That way, there’s no need to get extra plots or reduce harvesting time.

How to fuse Bastards in Romeo Is a Dead Man

Fuse Bastards at the altar in the church basement after collecting matching pairs from farm runs and boss fights. Select two identical ones from your inventory, confirm the fusion, and watch them combine into a stronger version with boosted stats like higher damage or health. Repeat fusions on the result to climb rarity tiers from Common to Legendary. Check the fusion tree menu for previewed outcomes before committing resources. This method clears inventory space while powering up your squad for tougher stages.

Besides gathering Bastard seeds, you can create new Bastards through fusion: You place a primary Bastard and a sub Bastard in a fighting arena, and the primary will consume the sub, thereby receiving a stat boost and possibly turning into a new type of Bastard.

There are a few important things to keep in mind when fusing Bastards:

  • A Bastard’s stats will always improve through fusion, so even if you’re not trying to create a new Bastard, feeding several common Bastards to a common SuicideAttack Bastard will get you a pretty overpowered minion.
  • If you want to follow a fusion recipe (see the list below), make sure you’ve selected them in the correct order. The Bastard you select first is the primary Bastard, the second is the sub Bastard. Otherwise, you’ll create a stronger sub Bastard instead of a brand-new fusion Bastard.
  • There’s a small chance of failure, leading to a victory for the “sub” Bastard rather than the primary one. This chance is only 1% in low-level Bastard fusion, but it may go up to 9%. It’s best to save your game first, so you may retry if necessary!

All Bastards in Romeo Is a Dead Man

The “All Bastards” section in Romeo Is a Dead Man centers on a group of misfits trying to survive in a chaotic farming-sim minigame filled with betrayal and uneasy alliances. Players manage resources, maintain fragile partnerships, and face moral choices that affect both harvest success and character outcomes. Humor mixes with tension as unpredictable events force players to balance greed with survival, revealing how thin the line between cooperation and treachery can be.

Every Bastard you’ve unlocked appears in the Bastardpedia. To see your discovered Bastards, speak with Luna in the Last Night’s Bastard farming room. If you’d like to look ahead, and get the fusion recipes for missing Bastards, here’s a complete list of every Bastard in Romeo Is a Dead Man.

Best Bastards for combat and boss fights

For general combat and especially boss fights, the standout Bastards are the ones that either lock enemies down, control aggro, or supercharge your Deadly Summer and damage output.

Core picks for bosses

  • Nosferatu – Top-tier for bosses because it drains enemy blood and rapidly fills Romeo’s Deadly Summer meter, letting you chain big attacks in longer fights.​

  • ManaBloom – Pulls enemies toward itself and distracts them, which is excellent for crowd control during chaotic phases or to set up other Bastards safely.​

  • FrostBolt – Fires ice shots that freeze enemies in place; a frozen boss or elite enemy gives you a free damage window and makes patterns safer to dodge.​

  • GreenTornado – Shines when the arena is full of adds, shredding groups and softening them so you can focus on the boss.​

Damage and utility staples

  • SentryCannon – One of the best all-rounders: constant, reliable DPS that scales extremely well when you fuse multiple copies into a stronger version.​

  • Graha Malla – Legendary “nuke”: massive charged attack with huge damage and knockback, ideal if you can keep it safe long enough to finish charging.​

  • DeadlyBowler – Strong line-attack that knocks enemies down and can explode after hitting a group, great for clearing lanes during boss add phases.​

Recommended loadouts

For typical boss fights (single tough target + adds):

  • Nosferatu (Deadly Summer charge)

  • ManaBloom (aggro/control)

  • FrostBolt or GreenTornado (lockdown / add clear)

  • SentryCannon or Graha Malla (main DPS / burst)

For mob-heavy encounters:

  • ManaBloom + GreenTornado to bunch and melt groups.

  • SlowBallad plus SentryCannon early game, where SlowBallad slows enemies and lets SentryCannon safely chip them down.​

If you tell me which Bastards you currently have, I can suggest a specific four-slot setup and fusion priorities for your next boss.

How to breed SentryCannon Bastards effectively

SentryCannon Bastards are ideal “fodder” and core DPS, so you want to mass-produce and then fuse them up through several tiers.

Why SentryCannon is ideal

  • Common seed drop, so you can stack a large number of them quickly for both combat and fusion fodder.​

  • Short cooldown and reliable ranged damage, which scales extremely well when you fuse higher-tier versions.

Step-by-step breeding loop

  • Plant every SentryCannon seed you find in your garden instead of mixing species; filling an entire plot with them keeps your “breeding” very focused.​

  • Keep playing stages while they ripen so you’re always coming back to a full harvest, rather than waiting out the 10-minute timer.

  • Harvest in bulk, then immediately spend duplicates in Bastard Fusion: always fuse SentryCannon + SentryCannon to create upgraded SentryCannon seeds with better stats.​

Fusion priorities and management

  • Treat early-tier SentryCannons as disposable; your goal is to climb to a few very strong, high-tier ones rather than hoarding weak versions.

  • Keep at least 2-4 high-tier SentryCannons unequipped in reserve so you can continue same-type fusion later without losing your main combat copies.​

  • Only start experimenting with cross-species fusions once you have several powerful SentryCannons; until then, same-type fusion gives the best value for boss and arena damage.​

Practical farming tips

  • Whenever you get non-Sentry seeds you don’t care about, grow and fuse them into new species, but keep SentryCannon seeds prioritized in your limited garden slots.​

  • If you’re going for the 777-summon achievement, lean even harder into SentryCannons: they’re fast to grow, cheap to use, and perfect for spamming in regular stages while you power up your best fused versions.​

If you tell me roughly how many plots you’re using and how far into the story you are, I can suggest a concrete “garden layout” and how many SentryCannon lines to maintain at once.
