Guillotina: The Home-Invading Nightmare

In typical Edmund McMillen fashion, Mewgenics doesn't just wait for you to find trouble—it brings the trouble to your doorstep. After you've cleared the Boneyard, you're put on notice: Guillotina is coming. This isn't your standard run-of-the-mill boss encounter. Instead of fighting through a dungeon to find her, she invades your home base. If you fail to repel her, she’ll treat your feline friends like "Frube yoghurts." We’ve analyzed the mechanics, and this fight is a brutal check on your breeding program and tactical positioning.

The 7-Day Countdown: Strategic Preparation

Once the warning triggers, you have a seven-day window. While you can skip ahead, we strongly advise against it. This is your time to min-max your roster. You are limited to using four retired cats, so the quality of your "pensioners" matters more than ever.

Breeding for Success

To survive Guillotina's 500 HP tankiness, you need to cycle through runs and retire cats with high stats and synergistic skills. Use furniture to boost your Comfort stat; the last thing you want is your prime candidates killing each other in a midnight scrap before the big fight. You’re looking for high Strength for your frontline and high Luck/Crit for your damage dealers.

Class Meta for the Raid

Our take on the ideal composition focuses on a balance of sustain and burst damage:

  • Hunter: Your primary DPS. Abilities like Marked and Arrow Flurry are essential for chipping away at that massive health bar.
  • Fighter: The meat shield. You need high Constitution to soak up hits, but don't ignore Intelligence if you have the skills to back it up.
  • Cleric: Non-negotiable for long-form sustain. If this fight drags, you need the heals.
  • Necromancer: Good for consistent pressure and self-healing. Pro Tip: Don't rely on reanimation here; there are no bodies to work with unless you bring a specific skill to generate them.
  • Thief: High-risk, high-reward. Great for backstabbing damage if you can keep them out of the AoE splash zones.

Battle Tactics: Handling the 500 HP Tank

Guillotina is a massive unit, taking up four tiles and dealing heavy Area of Effect (AoE) damage. The golden rule here? Spread out. If you clump your cats together, her basic Slice or Groundpound will wipe your squad in record time.

Countering the Move Set

  • The Inhale: This is her most disruptive move, swallowing a cat and removing them from play. If your cat is eaten, they need to use the Flail skill (25% escape chance). Alternatively, focus fire on Guillotina with your remaining units to force her to spit them out.
  • Toss: She’ll grab a unit and hurl them across the arena. We recommend having speed-boosting skills like Alpha or high movement stats to get your melee fighters back into the fray quickly.
  • Status Effects: Because of her high health, Damage over Time (DoT) is your best friend. Bleed, fire, and leeches are incredibly effective at softening her up while you focus on positioning.

The Aftermath: Ultra Retirement

Victory isn't just about survival; it's about the loot and the prestige. Defeating Guillotina nets you the Throbbing Gristle, a critical quest item meant for the Wall of Flesh at the end of the Caves. Don't fumble the bag—if you die on the way there, it's gone.

More importantly, the four retired cats who defended your home earn a "fancy glowing crown" and Ultra Retired status. While they can't defend the house again, they remain in your breeding pool. These are your genetic elites; use them to produce the next generation of powerhouses.
