How to Win Dead Cells+ Using Only Pet-Based Builds

Beating Dead Cells+ using only pets is a high-level challenge run that fundamentally alters the game's rhythm. Instead of engaging in the frantic, melee-focused combat the game is known for, you become a "summoner" or "controller." By relying exclusively on autonomous entities like the Mushroom Boi! and the Owl of War, you shift the gameplay loop from reflex-based aggression to strategic kiting and cooldown management.

While this playstyle removes the ability to burst down enemies with traditional weapons, it offers a unique vantage point to master enemy behavior. To succeed, you must transform your character into a support unit, ensuring your pets remain active, protected, and effective against the scaling difficulty of the castle’s later biomes.

Building the Ultimate Pet-Focused Loadout

In a pet-only run, your gear selection is your win condition. Since you are restricting your primary and secondary weapon slots, your "damage" comes entirely from your tactical items.

The Core Summons

• Mushroom Boi!: This is your early-game workhorse. It provides consistent melee pressure, but its true power lies in its secondary ability: the explosive charge. This can clear crowds or provide a massive burst of damage against bosses.
• Owl of War: The S-tier choice for this run. The Owl provides persistent, non-stop damage and can be reactivated to deal significant damage in an area. It is mobile, follows you through biomes, and doesn't suffer from the pathing issues that ground-based pets often face.
• Great Owl of War (Conditional): If you are playing on higher difficulties, the damage scaling of the Owl is essential to keep up with the health pools of elite enemies.

Synergistic Gear

Even if you aren't using weapons, you must fill your slots with gear that supports the "Tactics" stat. Look for items that provide:

• Cooldown Reduction on Kills: Essential for keeping your pets active during long biome runs.
• Damage to Enemies Affected by Burn/Poison: If your pets inflict status effects, ensure your gear affixes capitalize on these for multiplicative damage increases.
• Shields (If Allowed): Purists may forbid weapons, but if you allow a shield for parrying, it is your greatest defensive asset to stay alive while your pets work.

Scaling Damage and Managing Cooldowns

The biggest hurdle in a pet-only run is the "DPS wall." If your pets aren't strong enough, enemies will overwhelm you. You must prioritize the Tactics stat during every scroll selection. Tactics not only increases your pet damage but also reduces the cooldowns of your skills, which is the lifeblood of this build.

Essential Mutations for Scaling

1. Support: This is non-negotiable. It provides a massive damage boost to your turrets and pets when you are standing near them.
2. Parting Gift: Since you aren't attacking, this provides a little extra chip damage to clear weaker mobs.
3. Efficiency: This reduces the cooldown of your skills if you have a deployable out. It creates a feedback loop that keeps your pets on the field 100% of the time.
4. Tactical Retreat: Since you spend your time dodging, this mutation slows down enemies, giving your pets more time to land hits.

Mastering Positioning and Defensive Evasion

Without the ability to stagger enemies, you are vulnerable to being swarmed. Your gameplay must revolve around "kiting." You are not the fighter; you are the lure.

The "Kite and Wait" Strategy

• Chokepoints: Lead enemies into narrow corridors. Your pets have an easier time hitting targets in tight spaces, and you have fewer angles to dodge.
• Verticality: Dead Cells+ features many multi-level platforms. Use these to break line-of-sight for ranged enemies. Drop your pets, bait the enemy into firing, and jump to a different floor while your summons finish the job.
• The "Run-Back" Maneuver: If an elite enemy spawns, do not stand still. Deploy your pets, dodge away, and keep moving. Only move back into range to refresh your cooldowns or pick up loot.

Overcoming Boss Encounters

Bosses are the ultimate test for pet-only runs because they have "invulnerability phases" and high mobility.

• Patience is Key: You cannot rush a boss. If your pets are on cooldown, focus 100% of your energy on survival. Do not get greedy for a hit; your pets will do the work if you stay alive.
• Phase Management: Know when the boss is about to perform a screen-wide attack. Save your Mushroom Boi’s explosive dash for these windows to maximize damage while the boss is stationary.
• Observing Patterns: Because you aren't distracted by your own attack animations, you have the perfect view of the boss's telegraphs. Use this run to memorize the exact timing of every boss move, which will make your future standard runs significantly easier.

Common Mistakes to Avoid

• Aggressive Positioning: The most common way to die is trying to "help" your pets by getting too close. Stay behind them. You are the bait, not the striker.
• Ignoring Cooldowns: Never leave a fight with your pets on cooldown. If you clear a room and your pets are still active, wait for them to finish their cycle before moving to the next area to ensure they are available for the first enemy you encounter.
• Poor Stat Allocation: Do not split your scrolls between Brutality, Tactics, and Survival. If you are going all-in on pets, dump every single scroll into Tactics to maximize your skill damage output.

Final Thoughts on the Challenge

Beating Dead Cells+ with only pets requires a paradigm shift. You are trading the visceral satisfaction of the sword-and-board playstyle for a calculated, methodical approach to the game's architecture. It is a rewarding experience that forces you to respect enemy patterns and environmental hazards in a way that standard builds often bypass. By mastering the synergy between the Owl of War and the Mushroom Boi!, and prioritizing cooldown reduction above all else, you can turn the most chaotic encounters into a controlled, professional display of tactical superiority.
