What does Mirror do in Megabonk?

When you're hit, Mirror reflects the incoming damage and grants a brief invulnerability window.

How do you unlock Mirror?

Mirror is unlocked by default and available from the start.

Is Kevin + Mirror still viable after patch 1.0.7?

Yes, but the old i-frame exploit was fixed in v1.0.7. Treat it as a normal retaliation combo with proper sustain.

🧪 How Mirror Works

Mirror is a defensive item that turns enemy aggression against them: when you’re hit, you reflect the incoming damage and gain a brief invulnerability window (“I-frames”). This helps you push through dense waves or survive sudden bursts. If you’re new to items, check the full Items database for context and comparisons.

Key Properties

Triggers on being hit (contact or projectiles), returning damage to the source.
Grants short I-frames so follow-up hits in that window won’t land.
Pairs well with “on-take-damage” effects and sustain to stay safe while reflecting.

✓ Advantages

Mitigates burst via I-frames.
Converts defense into damage (reflect).
Enables on-damage proc builds.

✗ Considerations

I-frames are brief — not a permanent shield.
Still need positioning and sustain.

🛠️Patch 1.0.7 & later

Past “near-immortal” interactions (e.g., Kevin + Mirror i-frame abuse) were fixed in v1.0.7 and follow-up hotfixes. The combo remains playable, just no longer game-breaking.
