Pet Guide
Pets are one of the strongest progression systems in Arcana Historia. They provide both active combat power and team-wide passive buffs.
How Pets Work
Slot System — Positions 1, 2, 3
You have 3 pet slots (unlocked via the Pet Fence building):
| Slot | Role | Unlocked At | What It Does |
|---|---|---|---|
| Slot 1 (Active) | Combat Pet | Pet Fence Lv 0 | Pet physically fights alongside your team. Uses auto-attacks + active skill. |
| Slot 2 (Bench) | Passive Aura | Pet Fence Lv 7 | Pet does NOT fight. Its passive talent buffs your entire team. |
| Slot 3 (Bench) | Passive Aura | Pet Fence Lv 14 | Same as Slot 2 — another team-wide passive aura. |
Critical: Bench pet passives apply to your ENTIRE team, not just one hero. This makes them incredibly efficient.
Key rules:
- Passives are tagged "Only active when NOT in combat slot" — they ONLY work in slots 2 and 3
- You can swap your active pet mid-run, but there's a 120-second cooldown between swaps
- Pets in bench slots contribute 6% of their stats to your heroes (inheritance ratio)
- Slot 2 and Slot 3 are identical — there is no difference between them. Pick your two best passives.
Which Pet Goes Where?
Slot 1 (Active) — Always your tankiest or most useful active skill pet:
- Bat (Vampirism heal) is the default best for sustain
- Mars (Combo) for auto-attack builds that want extra hits
- Halo (Dispel) for shield-heavy boss floors
Slots 2 & 3 (Bench) — Always your two strongest passive talents:
- These are your biggest team-wide multipliers
- Order between slot 2 and 3 doesn't matter — both activate equally
- Prioritize passives that match your team's damage type
Pet Stats
Pets have their own HP, ATK, DEF growths. The active pet fights using these stats.
- Growth ranges are random within a defined range per pet species
- Stats are multiplied by the pet's quality ratio
Pet Quality
| Quality | Ratio | Level Cap | Upgrade Cost |
|---|---|---|---|
| E | 0.24 (24%) | Low | Starting quality |
| D | 0.32 (32%) | Medium | 240 rare points |
| C | 0.425 (42.5%) | Medium | 240 rare points |
| B | 0.565 (56.5%) | High | 720 rare points |
| A | 0.752 (75.2%) | High | 3,000 rare points |
| S | 1.0 (100%) | Max | 76,800 rare points |
Quality upgrade is the single biggest stat multiplier for your active pet. Going from E (24%) to S (100%) is a 4.17x stat increase.
Pet Skills
Active Skill (Combat Pet Only)
Each pet has a unique active combat skill that triggers in battle:
- Unlocked and upgraded by reaching star levels (★1 through ★5)
- Higher stars = stronger skill effects
- Star-up requires specific food items + reaching level thresholds
Passive Ability (Bench Only)
Each pet has one passive ability with 5 upgrade levels:
- Applies to your entire team when the pet is on the bench
- Upgrades cost gold + pet-specific materials + rare crystals
- This is where most of your pet investment gold should go
Pet Feeding & Raising
Food Types
- Each pet has 4 preferred food types
- Preferred food gives bonus points (check the "is_prefer" field)
- Snacks also build up pet points for various bonuses
Pet Products
- Pets produce items over time (like a farm)
- Products include: rare crystals, gold, pet materials
- Higher quality pets produce more/better items
Pet Hatching
- New pets come from Pet Eggs
- Eggs obtained from: shop, gacha, events
- Each egg has a hatch time (varies by pet rarity)
Priority: Where to Invest
Gold Priority for Pets
- Bench pet passive upgrades (Levels 1→5) — biggest team-wide impact
- Active pet quality upgrades (E→D→C→...) — biggest stat jump for combat
- Active pet star-ups — unlock stronger combat skills
- Pet food — keep pets leveled for better stat contribution
Which Pets to Prioritize
Active Pet (Combat):
| Pet | Why |
|---|---|
| 小蝙蝠 (Bat) | Heals random ally on each auto-attack (15% ATK). Best sustain. |
 迅猛龙 ( Raptor) |
High ATK growth, strong combat stats |
Bench Pets (Passive Priority):
| Pet | Passive | Effect at Max | Why |
|---|---|---|---|
| Raptor |
Swift | +55% ATK Speed for team | Massive DPS multiplier |
 Cave Spider |
Corrode | -45% enemy Poison Resist | Essential for Poison Archer builds |
| Lava Raptor |
Lethal | +50% Crit for team | Universal DPS boost |
 Metal Slime |
Iron Wall | DEF + DR for team | Survivability |
 Bat |
Bloodthirst | Team auto-attack heals 10→20% ATK (0.5s CD at max) | Sustain |
F2P Pet Strategy
Early Game (Depth 0–50)
- Use whichever pet you hatch first as active
- Get Bat as active ASAP for healing
- Bench 1: Raptor (ATK speed passive) if available
- Start upgrading bench passives with gold — Level 1 is cheap
Mid Game (Depth 50–120)
- Push active pet to Quality C minimum
- Upgrade Raptor passive to Level 2–3
- Add Cave Spider if running Poison Archer
- Start working on a second bench passive
Late Game (Depth 120+)
- Target active pet Quality B→A
- All bench passives to Level 3–4
- Consider specialized bench pets based on team comp
- Quality S (76,800 rare points) is a long-term whale/endgame goal
