Overview
Spirit Fox is the ninth Hero Pet unlocked at Pet House Level 9 (Town Hall 16), introducing the powerful Spirit Walk ability that grants paired heroes temporary invisibility every 6 seconds for 4-second duration at max level. During invisibility, the hero becomes completely untargetable by defenses, traps, and enemy troops—essentially becoming a ghost that can move and attack without retaliation. However, Spirit Fox itself remains visible and targetable throughout the ability. With 2,400 HP, 130 DPS, and movement speed 28, Spirit Fox creates a hit-and-run playstyle where heroes alternate between visible (2 seconds) and invisible (4 seconds) states, allowing them to bypass dangerous defenses.
Spirit Fox revolutionized TH16-17 meta by enabling heroes to bypass the most lethal defenses in the game—single-target Inferno Towers, Scattershots, Monoliths—through periodic invisibility that breaks target locks. Royal Champion + Spirit Fox became the dominant meta combination: RC targets defenses while cycling invisibility every 6 seconds, making her nearly unkillable as she destroys high-value defenses safely. The invisibility also prevents trap triggering (Spring Traps, Bombs, Seeking Air Mines don’t activate on invisible heroes), allowing safe navigation through trap-heavy areas. However, Spirit Fox provides no direct healing, stunning, or damage amplification like other pets—relying entirely on invisibility for value. Spirit Fox pairs best with Royal Champion (defense-focused hero benefits from safe engagement windows) and Archer Queen (Queen Charges benefit from periodic damage avoidance), but has limitations with Barbarian King who may prefer Phoenix resurrection for deep aggressive dives.

Key Attributes: Spirit Fox has movement speed 28, attack speed 1.5 seconds, attack range 4.5 tiles, and targets buildings. Special Ability – Spirit Walk: Grants hero invisibility for 4 seconds every 6 seconds (automatic, periodic). Invisible heroes are untargetable by defenses/traps/troops. Important: Spirit Fox itself remains visible and targetable during hero invisibility. Attack Type: Ranged single-target (ground unit).
⚔️ Best Hero Pairings
Royal Champion (Best Pairing)
Spirit Fox + Royal Champion = most powerful TH16-17 meta combo, defining competitive play. RC targets defenses while Spirit Fox cycles invisibility every 6 seconds—RC becomes invisible for 4 seconds, destroying defenses safely without taking damage, then visible for 2 seconds (minimal exposure). This 66% invisibility uptime makes RC nearly unkillable, allowing her to eliminate Inferno Towers, Scattershots, and Monoliths without sustaining lethal damage. Essential pairing for RC-focused attacks at TH16-17.
Archer Queen (Strong Pairing)
Excellent for Queen Charge strategies at TH16+. Queen Charges benefit massively from periodic invisibility—when Queen becomes invisible, defenses lose target lock and must reacquire (wasting time), Queen deals damage without retaliation for 4 seconds. The 6-second cycle allows Queen to engage dangerous defenses (Inferno Towers, Eagle Artillery) with periodic safety windows. Works particularly well with Invisibility Vial equipment for extended invisible periods.
Barbarian King (Moderate Pairing)
Viable but
Phoenix often superior for King’s aggressive playstyle. Spirit Fox’s invisibility helps King survive burst damage from Inferno Towers and Scattershots during deep dives. However, King benefits more from resurrection (second chance after death) than periodic invisibility (damage avoidance). Use Spirit Fox with King for strategic flanking attacks where invisibility enables surprise positioning.
Grand Warden (Poor Pairing)
Not recommended. Grand Warden is support hero who stays behind army—invisibility provides minimal value since Warden rarely takes direct fire. When Warden does need protection, Eternal Tome (built-in invincibility) is superior to Spirit Fox invisibility.
Electro Owl or
Poison Lizard offer better Warden support with offensive capabilities.
🎯 Strategic Tips
Spirit Walk Cycle – 4s Invisible / 2s Visible
Spirit Fox grants invisibility for 4 seconds every 6 seconds = hero is invisible 66% of the time. Cycle pattern: Hero visible for 2 seconds → invisible for 4 seconds → visible for 2 seconds → repeat. During 2-second visible windows, heroes are vulnerable to all defenses. Time hero ability activations (RC’s Rocket Spear, Queen’s Royal Cloak) during invisible windows for maximum safety.
Hero-Only Invisibility
Critical limitation: Spirit Fox grants invisibility ONLY to the paired hero—Spirit Fox itself remains visible and targetable throughout. This means defenses can still target and kill Spirit Fox while hero is invisible. Protect Spirit Fox by positioning hero to tank damage during visible windows. If Spirit Fox dies, invisibility effect ends permanently for remainder of attack.
Trap Immunity During Invisibility
Invisible heroes do NOT trigger traps—Spring Traps, Bombs, Skeleton Traps, Seeking Air Mines all ignore invisible heroes. This allows heroes to walk through trap-heavy compartments safely during invisible windows. Use invisibility timing to navigate known trap zones: become invisible → cross trap area → become visible after clearing danger zone. Eliminates need for excessive trap-testing troops.
Recall Spell Synergy
Pair Spirit Fox with Recall Spell for double-push strategies. Execute first push with RC + Spirit Fox, eliminate 3-4 defenses using invisibility. When invisibility cycle becomes unfavorable or RC takes heavy damage during visible window, use Recall Spell to extract RC. Heal/reposition, then redeploy for second push with fresh invisibility cycles. Advanced TH16-17 strategy for maximizing RC impact.
Defense Targeting Reset
When hero becomes invisible, all defenses targeting that hero lose target lock and must reacquire new target. This wastes 1-2 seconds of defense attack time while they search for new target. Against slow-firing defenses (X-Bows, Eagle Artillery), invisibility timing can skip entire attack cycles—defense aims at hero, hero becomes invisible, defense reacquires different target, hero becomes visible after defense fires elsewhere.
🛡️ Countering Spirit Fox
Target Spirit Fox Directly
Focus defenses on Spirit Fox (which remains visible) rather than the invisible hero. Spirit Fox has only 2,400 HP—dies to 2-3 Archer Tower volleys or single Scattershot hit. Position Wizard Towers, Archer Towers, and Mortars to cover areas where RC typically paths with Spirit Fox. Once Fox dies, hero loses invisibility permanently, becoming fully vulnerable to all defenses for remainder of attack.
Splash Damage Defenses
Scattershots and Eagle Artillery deal area damage that affects invisible heroes indirectly—while they can’t target invisible heroes, their splash radius damages nearby area. Position Scattershots to cover multiple defenses simultaneously. When invisible RC destroys an Inferno Tower, nearby Scattershot’s area damage hits RC even though she’s invisible. Eagle Artillery’s 3-tile splash radius creates unavoidable damage zones.
Multi-Target Inferno Towers
Set Inferno Towers to multi-target mode. Multi-target Infernos engage both hero AND Spirit Fox simultaneously during visible windows. With Fox at 2,400 HP, multi-target Inferno eliminates Fox in 4-5 seconds while also damaging hero. Once Fox dies, hero loses invisibility protection. Position multi-target Infernos inside core compartments where RC/Queen typically path.
Skeleton Traps During Visible Windows
Deploy Skeleton Traps to trigger during hero’s visible windows (2 seconds between invisible phases). Skeletons distract hero, forcing hero to engage skeletons instead of defenses, wasting precious attack time. Since invisibility doesn’t trigger during skeleton combat, hero remains vulnerable longer. Position Skeleton Traps near high-value defenses (Inferno Towers, Eagle Artillery) to maximize distraction during visible phases.
