Puzzles & Survival Pet System Guide and Upgrade Priorities

The Pet System in Puzzles & Survival introduces companion creatures that provide static sanctuary passives and active march buffs. To maximize account progression, prioritize leveling a single high-rarity companion that matches your primary troop type, unlock inexpensive baseline economic passives on secondary pets, and save premium summon tokens for server growth events.

How Pets Function: Passives vs. March Assignments

Pets reside in dedicated housing within your sanctuary and operate alongside your existing heroes, gear, and tactical bioenhancers without replacing them. Their bonuses fall into two separate categories:

Bonus Type	Activation Condition	Primary Effects
Sanctuary Passives	Unlocked automatically upon owning and leveling the pet	Account-wide economy boosts, gathering speed, troop defense, and hospital capacity
March Assignments	Assigned directly to an outgoing squad	Direct combat stat increases, troop-specific damage output, and triggered combat procs

Sanctuary passives remain active at all times, even when the companion is not physically deployed on the world map. March bonuses require you to attach the companion to an active march targeting zombie lairs, enemy bases, or alliance objectives.

Matching Pets to Your Troop Specialization

Because progression supplies are limited, concentrate investment on companions that complement your primary combat focus rather than spreading resources evenly across multiple unit types.

Fighter Specialists: Prioritize companions providing flat Fighter DEF, Fighter HP, and percentage-based Fighter damage reduction to reinforce frontline survivability.
Shooter Specialists: Prioritize companions offering Shooter ATK and critical damage multipliers to increase backline damage output.
Rider Specialists: Prioritize companions granting Rider ATK, march speed, and burst strike capabilities for fast map skirmishes.
Universal Economy: Retain secondary pets at base investment levels to capture low-tier gathering, construction, or research passives without consuming rare evolution items.

Upgrading, Tier Evolution, and Skill Slots

Pet progression follows a two-tier advancement structure: standard numerical leveling and milestone evolution.

Resource Allocation

Direct roughly 80% of your daily pet food and experience supplies into your highest-rarity combat companion until it reaches its current evolution cap. Only divert excess food to secondary companions when your main pet is blocked by evolution requirements, using the surplus to unlock early sanctuary passives.

Evolution and Skill Priority

Tier evolution requires specialized evolution stones or duplicate companion copies. Evolving a pet raises its maximum level ceiling and unlocks additional skill sockets for specialized skill scrolls. When choosing and equipping skills, follow this priority:

Percentage Damage Multipliers: Equip percentage-based attack or troop lethality increases, which offer superior long-term scaling compared to flat numerical boosts.
Mitigation and Health: Add damage reduction or troop HP bonuses to sustain rallies during prolonged fights.
Turn-Based Procs: Align triggered combat abilities with the combat speed and activation cycles of your main hero roster.

Launch Strategy and Resource Traps

To avoid wasting scarce materials during the initial rollout, keep these rules in mind:

Avoid Over-Investing in Common Pets: Lower-tier companions have low attribute caps. Investing heavily in them drains resources that are better reserved for elite and legendary companions.
Check Material Reset Costs: Before committing evolution stones to placeholder companions, inspect the pet interface to confirm whether experience and upgrade materials can be reset and refunded for free or at a resource cost.
Save Summons for Milestone Events: Hold advanced recruitment tokens and summon currencies until a server-wide pet growth event appears, allowing you to earn tiered event rewards alongside your regular summons.
