Sephiria Glass Cannon Build — Maximum Damage, Maximum Risk

The Glass Cannon build sacrifices all defense for maximum damage. If you're confident in your dodging and want the fastest clear times, this is the build. One mistake can kill you — but everything dies in one hit too.

Not recommended for Hard Mode or new players. You will die. A lot.

The Build: "Blade Storm"

This build uses the Katana for its dash-attack synergy. Iaido (3x dash damage) + Blood Draw (heal on kill) + bleed stacking = explosive damage with just enough sustain.

Weapon: Katana

Why Katana:

Iaido upgrade gives 3x damage on dash attacks — highest burst in the game
Attack speed is naturally high
Bleed DoT adds passive damage
Dash attacks have invincibility frames — your defense is dodging

Essential Upgrades (Priority Order)

Iaido — Dash attack does 3x damage. This IS the build.
Bleed — Attacks cause bleeding (stacks up to 5). Free damage.
Attack Speed +25% — More slashes = more bleed stacks.
Blood Draw — Heal 5% on dash kill. Your only sustain.
Counter Stance — Perfect dodge triggers free counter slash. Adds another damage window.

Artifact Setup

Slot	Artifact	Why
1	Berserker Mask	+50% damage when below 50% HP. Core of the build.
2	Bloodlust Blade	+10% damage per kill (max 5). Snowballs fast.
3	Assassin's Mark	Backstabs do +100% damage. Combo with dash positioning.
4	Rage Stone	+30% attack speed when no potion remaining.
5	Crit Crystal	+25% crit chance. Crits can one-shot trash mobs.

No defensive artifacts. No HP boosts. If you get hit, you die. That's the point.

Talent Picks

Berserker: +1% damage per 1% missing HP. The lower you are, the harder you hit.
Adrenaline: Dash cooldown -30% when below 30% HP. More dashes = more Iaido.
Bloodthirst: Kill resets dash cooldown. Infinite dashes if you keep killing.
Risky Strike: +100% damage for 3s after perfect dodge. Counter Stance synergy.

Playstyle

Room Clear

Dash through the first enemy (Iaido + Bleed), immediately dash to the next (Bloodthirst resets dash), repeat. A room of 6 enemies should take 6 dashes — about 3 seconds.

Boss Fights

Wait for the boss to attack
Perfect dodge (triggers Counter Stance + Risky Strike)
Dash through the boss from behind (Iaido 3x + Assassin's Mark + Berserker)
Repeat

With full stacks, a single dash can deal 15-20x your base attack damage. Most bosses die in 5-10 dashes.

Managing HP

The trick is staying at low HP without dying. Berserker Mask, Berserker talent, and Adrenaline all need you below 50% HP. Get hit once on purpose at the start of each room, then never again.

When This Build Fails

Bullet hell bosses — Demon King Phase 3 has too many projectiles to dodge perfectly. Switch to a safer build.
Hard Mode with armor modifiers — Bleed doesn't scale with armor pierce. Consider Greatsword instead.
Co-op — You'll die before teammates can revive you. Use Co-op Build instead.

Glass Cannon Variations

Staff Glass Cannon

Replace Katana with Staff. Grab Elemental Mastery + Meteor + Elemental Overload. Drop all mana artifacts for pure damage. One-shots rooms with Triple Element combos. Even riskier — no dash invincibility.

Crossbow Sniper

Piercing Bolts + Explosive Bolts + Crit Crystal. Kill everything from across the room. Safest glass cannon but lowest sustained DPS.

Is Glass Cannon Worth It?

For speedrunning and Normal Mode: absolutely. Clear times can be 2-3x faster than tanky builds. For Hard Mode progression: no. Use the Survivor Mage build instead and switch to glass cannon once you're confident.
