Let's get this out of the way: Thor clears waves better than Blade. Wider AoE, less setup, less babysitting.
But bosses? That's Blade's arena.
This build is built around one loop: charge Ultimate fast → buff with Daywalker Dash → dump Ultimate into a boss that's already bleeding. Nail the timing and Blade turns Nightmare 300 bosses into confetti.

↖ Build Philosophy
Stop building Blade like a generalist. He's a specialist.
| Priority | Focus | Why |
|---|---|---|
| Very High | Ultimate charge speed | This IS the build |
| Very High | Daywalker Dash amp | Buffs the burst window |
| Very High | Missing-HP damage | Scales harder as boss HP drops |
| High | Close-range damage | Works on mobs AND bosses |
| Med-High | Precision / Crit | Whichever your gear supports |
| Medium | Boss damage | Fine, but situational |
One rule governs every decision: does this help me cast Ultimate more, or hit harder when I do? If not, skip it.
↖ Why Missing-HP Scaling Is the Secret Sauce
Blade's Ultimate looks mediocre on a full-HP boss. Drop that boss to 40-50% HP and it becomes an execution button.
| Boss HP | Ult Value | Play It Like |
|---|---|---|
| 100-90% | Weak | Delay if teammates are hitting it |
| 90-70% | Decent | Use it if boss is grouped/stable |
| 70-50% | Strong | Start hunting your burst window |
| 50-40% | Execution range | Clean Ult = massive chunk or kill |
| <40% | Nuke territory | Commit fully |
In squad play, wait 5-10 seconds before your first Ult. Let teammates chip HP first — it makes your Feast of the Hunt scaling absurd.
↖ Traits: What to Actually Take
- Ultimate ability charge speed — 5 points, non-negotiable. This is the whole build.
- Daywalker Dash damage amp — mandatory. Useless without this.
- Sword-hit Ult recovery — high priority. Keeps Ult flowing between fights.
- 1 point in Attack Speed — smooths out charge-building. Nothing more.
- Skip Hunter's Aura. Knockback pushes enemies OUT of your Ult zone. You want them trapped, not scattered.
↖ Gear: Enhancement Stack
Four enhancements do the heavy lifting:
| Enhancement | Amount | Purpose |
|---|---|---|
| Feast of the Hunt | 2-3 | Missing-HP scaling — core damage |
| Blade Shadows | 1 | Overall damage profile |
| Synergy of Swords | 1 | Sword flow + Ult uptime |
| Unfazed | Optional | Extra burst window with Dash/spin |
Squad setup: 3x Feast of the Hunt + 1 Blade Shadows + 1 Synergy of Swords.
Solo setup: drop to 2x Feast of the Hunt, add a second Blade Shadows or Synergy of Swords instead. No teammates chipping HP means you need self-sufficient damage early.
↖ Stat Priority
| Stat | Priority | Note |
|---|---|---|
| Total damage bonus | Very High | Best universal stat, grab it everywhere |
| Close-range damage | Very High | Hits mobs AND bosses — better than boss damage |
| Precision | High | ~18,000 Precision / 15% rate feels great |
| Crit | High | Use if your Crit rolls are stronger |
| Boss damage | Medium | Only helps in boss phase |
Don't force Precision over Crit or vice versa — take whichever your actual gear rolls support.
↖ Best Arcana
Final Prey (+30% Ultimate charge speed) is mandatory. It's the engine, not a bonus.
| Arcana | Priority |
|---|---|
| Final Prey — Ult charge +30% | Mandatory |
| +5% damage reduction | Very High |
| Close-range bonus damage | High |
| +10% damage bonus | Med-High |
| +15% health | Medium |
Blade fights in melee range constantly. 5% damage reduction lets you stay aggressive instead of dying mid-charge. Damage you never dealt because you died? Zero. Every time.
↖ The Core Combo: Dash Into Ultimate
Dash first. Ultimate immediately after. That's it.
| Step | Action |
|---|---|
| 1 | Let boss lose some HP first (squad play) |
| 2 | Get close — Ult needs proximity |
| 3 | Daywalker Dash |
| 4 | Ultimate — immediately, don't wait |
| 5 | Keep attacking through the Ult window |
| 6 | Rebuild charge with sword hits, repeat |
Wait too long after Dash and the amp expires. Cast Ult from a bad angle and the boss walks out of the zone. Timing beats gear quality every time.
↖ Two Bosses? Prioritize.
| Situation | Move |
|---|---|
| Both grouped | Dash → Ult, no hesitation |
| One's moving | Hold half a beat, reposition |
| Split far apart | Focus the lower-HP one |
| One near execution range | Ult secures the kill |
| Both above 90% HP | Delay if teammates are working |
Pro tip: aim slightly downward on cast. Tightens the damage area in close-range fights and stops you wasting burst on awkward angles.
↖ Wave Clear: Good Enough, Not Great
| Element | Performance |
|---|---|
| Small mobs | Good |
| Dense groups | Very good |
| Spread enemies | Average — needs grouping |
| Elites | Strong via burst |
| Full-map clear | Weak vs. Thor |
Waves exist to feed your Ult charge, not to be your highlight reel. Sword-hit kills recharge Ult — stay active, don't hoard cooldowns.
Ult coming back slow? Check three things: are you landing sword hits consistently, are you Dashing into grouped mobs, are you wasting Ult on scattered targets.
↖ Common Mistakes That Kill Your Damage
| Mistake | Fix |
|---|---|
| Ult before Dash | Dash first, always |
| Ult at full boss HP | Wait for HP loss in squad play |
| Chasing boss-damage rolls | Prioritize close-range damage instead |
| Letting bosses walk out of Ult | Cast when they're grouped/committed |
| Skimping on charge speed | Max it — it's the whole build |
| Over-investing in wave clear | Stay Ult-focused, that's the payoff |

↖ FAQ
↖ Is Blade the best Nightmare 300 hero?
No — not for wave clear. But as a boss execution specialist, few heroes match his burst once HP scaling kicks in.
↖ Does this build work solo?
Yes, with a tweak: run 2 Feast of the Hunt instead of 3, and add extra Blade Shadows or Synergy of Swords. No teammates chipping HP means you need more self-generated damage.
↖ Why does my first Ultimate feel weak?
Because it's landing on a near-full-HP boss. Feast of the Hunt needs missing HP to shine. Wait 5-10 seconds in squad play before your opener.
↖ Precision or Crit — which one?
Whichever your gear actually rolls better. Don't force either stat just to match a meta label.
↖ Can Blade one-shot bosses?
With strong gear and clean timing, he can delete bosses from ~40% HP. Not a guaranteed full-HP one-shot — this is an execution tool, not a nuke button.
↖ Bottom Line
Stop building Blade to compete with Thor's wave clear. Build him to end boss fights.
Max Ult charge speed. Run Final Prey. Stack Feast of the Hunt. Dash before every Ultimate. Wait for HP to drop in squad play before your opener.
Get the timing right, and Blade stops feeling like a support-tier hero and starts feeling like the reason your run ended three minutes faster.
