How to Beat Tachy in Stellar Blade

Tachy is one of the most memorable duels in Stellar Blade. Fought in Matrix 11, this multi-phase encounter starts as a relatively grounded sword fight and escalates into something far more monstrous as Tachy sprouts a black wing and a tentacle arm. The fight rewards patience, clean dodges, and disciplined punishes more than brute aggression. This guide breaks down every phase and explains how to manage your resources from start to finish.

Story Context and Location

Tachy awaits in Matrix 11, and the encounter carries significant story weight. The arena is tight, leaving little room to run away and forcing you to engage on Tachy’s terms. Because the fight has multiple forms, you cannot burn all of your healing or Beta meter in the opening minutes. Treat each phase as its own mini-boss and save resources for the later, more dangerous patterns.

Phase 1: Sword Patterns

The first phase is a humanoid sword duel. Tachy uses a mix of single slashes, delayed combo finishers, and lunging thrusts. Most of his attacks have a clear startup, but the timing can bait early dodges. The best approach is to stay at mid-range, let him swing first, and then counter with a short combo before retreating.

Key habits for phase 1:

• Watch for the delayed overhead slash. It has a longer wind-up than the other attacks and is your best punish window.
• Do not block entire combos. Parry or dodge the first hit, then reposition rather than trading.
• Only use Beta skills when he is recovering from a whiff. Using them blindly will get you countered.

Black-Wing Phase

Once Tachy sprouts his black wing, the tempo changes. He gains new aerial and dashing attacks that cover more ground and recover faster. The wing also lets him reposition quickly, so staying directly behind him is no longer safe. Instead, keep a medium distance and wait for him to land after a wing-assisted lunge. That landing animation is the most consistent opening in this phase.

During the black-wing phase:

• Avoid chasing him when he rises. Wait for the dive, then punish.
• His combo length increases, so count the hits before you attack.
• If you have Blink, use it to close the gap after a dive and secure damage before he recovers.

Tentacle Arm Phase

In the final phase, Tachy’s tentacle arm extends his reach dramatically. Attacks come from unexpected angles and can catch you if you rely on muscle memory from the earlier phases. The tentacle has a slightly longer wind-up on its heavy swings, but the range means you need to dodge earlier than it looks. Stay calm, watch the limb itself rather than Tachy’s body, and punish only the slowest recoveries.

Healing management becomes critical here. By this point you should still have at least one recovery item in reserve, and your Beta meter should be full or nearly full. Use a big Beta attack after a tentacle whiff to push toward the end of the fight, then finish with basic combos.

Recommended Skills and Exospines

The right build smooths out Tachy’s difficulty curve:

• Blink — invaluable for closing distance after his dashes and dives.
• Parry window extensions — help against the delayed sword attacks in phase 1.
• Beta recharge skills — give you more big punishes across the long fight.
• Health and defense passives — add padding for the tentacle phase where mistakes are easiest.
• Stagger or shield-break upgrades — let you down him faster during the rare moments he is posture-broken.

Healing and Resource Management

Tachy’s fight is long enough that resource discipline decides the outcome. Follow these rules:

• Use small heals after avoidable chip damage, but keep your largest heals for phase 3.
• Enter the tentacle arm phase with full or near-full Beta meter.
• Do not waste Beta on blocked attacks; only spend it during guaranteed openings.
• If you run low on items, backtrack to a camp and restock rather than banging your head against the wall.

Final Tips

Tachy is a pattern-recognition exam. The first few attempts should be treated as practice: learn the sword delays, learn the dive timing, and learn the tentacle range. Once those clicks, the fight becomes one of the most satisfying in the game. Stay patient, keep your resources for the final phase, and let Tachy come to you.
