Effect: Reflects all incoming contact damage back at attackers and grants 0.5 seconds of invulnerability. 7-second cooldown per copy.
Unlock: Available from the start - no unlock required
Mirror is an Epic item that triggers when you take contact damage from an enemy colliding with you. When it fires, it reflects that damage back at all enemies in a cone in front of you and grants 0.5 seconds of invulnerability. The base cooldown is 7 seconds per copy - Mirror does not trigger on every hit, only the next contact hit after the cooldown expires.
Reflected damage scales with incoming damage and how many copies you hold. Per community testing at megabonkinfo.org, the formula is: reflected damage = incoming damage x (1 + 0.25 x copies) x Damage Multiplier. One copy reflects 1.25x the incoming damage, two reflect 1.5x, three reflect 1.75x. Damage Tome investment directly increases reflected damage. Mirror also has a proc coefficient of 1.0, meaning when it fires it can trigger other on-hit items normally.
Mirror only triggers from contact damage when an enemy physically collides with you. It does not reflect boss projectile attacks or ranged enemy shots. If you rely on Mirror for protection during ranged boss phases, it will not fire. The item is most valuable in swarm situations where many enemies are in direct contact range.
The most well-known Mirror interaction is the Kevin + Mirror combo. Kevin has a 25% chance to deal self-damage when you hit an enemy. That self-damage counts as taking a hit, which triggers Mirror's invulnerability window. At high enough attack speed, Kevin procs happen frequently enough that Mirror's 0.5-second invulnerability windows chain together into near-continuous protection.
The true immortality version of this combo was patched in v1.0.7 and further adjusted in v1.0.12. Multiple community guides confirm it no longer creates permanent immunity but still provides frequent invulnerability bursts that dramatically reduce damage taken in dense swarms. The developer's patch note on the combo read "Kevin no longer makes you invincible (rip kevin abusers)" - the combo is still strong, just no longer exploitable.

| Invulnerability window | 0.5 seconds per trigger |
| Cooldown | 7 seconds base (1 copy) |
| Trigger source | Contact damage only - not projectiles |

The Gamer Goggles wiki page confirms Kevin's self-damage doesn't trigger Mirror's reflect. Kevin's damage hits your HP directly and does not consume Mirror charges - the two work independently. This means Kevin is pure upside for Mirror builds: it generates invulnerability windows without "wasting" Mirror's cooldown on self-inflicted hits.
Megachad - Multiple community guides specifically name Megachad as the top character for Mirror and Kevin + Mirror builds. His Flex passive blocks incoming damage and stuns nearby enemies on a cooldown that decreases by 0.2 seconds per level, stacking with Mirror's invulnerability windows to create overlapping protection layers. His AFK Aura playstyle generates constant hits that keep Kevin procs cycling, and his high base HP means each hit that lands before Mirror fires is less punishing proportionally.
Athena - Community guides specifically describe the Kevin + Mirror + Athena combination. Athena's Lock In passive deals more damage at low HP. Kevin's self-damage keeps her in the low-HP zone without killing her, activating the damage bonus. Mirror's invulnerability then protects that low-HP state from enemy hits that would push her out of it. The three items together create a controlled low-HP state that is both aggressive and survivable.
Bandit - Bandit's +1% Attack Speed per level passive is directly cited in the meta guide as making him the best character for Kevin + Mirror - more attack speed means more Kevin procs per second, which means more Mirror invulnerability triggers per second. The meta guide explicitly states Bandit is the best Kevin + Mirror abuser due to this attack speed scaling.
When Mirror is off cooldown and you take contact damage from an enemy, it reflects that damage back at enemies in a cone in front of you and grants 0.5 seconds of invulnerability. Reflected damage = incoming damage x (1 + 0.25 x copies) x Damage Multiplier. Base cooldown is 7 seconds per copy. Mirror only triggers from contact damage - not boss projectile attacks.
Kevin's 25% self-damage proc counts as taking damage, which activates Mirror's 0.5-second invulnerability window. At high attack speed, Kevin procs happen frequently enough to chain those windows into sustained protection. The true immortality version was patched in v1.0.7 and v1.0.12. The combo now provides frequent invulnerability bursts - still one of the strongest defensive combinations but no longer a true exploit.
Yes. Each additional copy increases the reflect damage multiplier by +0.25x and makes Mirror available more often as cooldown overlaps. Two copies reflect 1.5x incoming damage, three reflect 1.75x. The invulnerability window stays at 0.5 seconds regardless of copy count.
No. Mirror only reflects contact damage from enemies physically colliding with you. Boss projectile attacks and ranged shots do not trigger Mirror. It is most effective in swarm situations with high enemy density rather than against ranged boss patterns.
