How to Beat the Mirror King

The Mirror King: a knight in a spiked crown, his face hidden behind a visor, wearing a purple-grey robe and holding a crystal scepter

The Mirror King is the stage guardian of "Forgotten Ruins", the fourth stage of Endless Curse, and arrives at 9:00. He summons reflections that shoot alongside him and suddenly blinks next to you, so one slip and you're caught in bullets from two or three directions. The key: clear reflections first and read his blinks.

02Mirror King's attacks

The Mirror King is a ranged boss who likes to fight from afar. His ranged attacks are reflections, Bullet Fan and blinking; get close and he blinks away or pushes you off with Stomp.

YouHe can appear anywhere on this ring

Mirror Blink

Vanishes in a flash and reappears near you, immediately firing a fan of five bullets.

How to dodge: When he disappears, get ready to sidestep, and don't walk toward where he just was. He often follows other attacks with this.

MirrorYouSafe outside

Stomp

Only used when you're very close: one stomp that hurts everything in a ring around it.

How to dodge: When it's on top of you, watch for the glowing ring at its feet, step outside, then come back. Melee classes eat this one the most.

Mirror ReflectionReflectionYou

Mirror Reflections

Summons two reflections next to him that stand back and shoot at you. Each has only 8% of his health, at most two at a time, and he replaces any you destroy.

How to dodge: They're fragile, so clear them as you go. Otherwise you get shot from two sides and dodging gets hard.

MirrorYou Sidestep first

Bullet Fan

Winds up, then fires a fan of 7 bullets at you.

How to dodge: Move sideways when his hand lights up; the further away, the wider the gaps.

03Below half health: enrage

When Mirror King drops below half health, the screen shows "Mirror King is enraged!". After that:

  • Movement speed goes up 15%, so it closes in faster (to about 44%).
  • It attacks 25% more often, and Stomp, Bullet Fan get 20% less warning time.
  • After each attack there's a 35% chance it chains straight into the next one with barely a pause.
  • Bullet Fan: Enraged: 9 bullets at a time.

Once enraged, his Bullet Fan fires 9 shots and his attacks come thicker, often chaining right after a blink. Clear reflections the moment they appear, so you're never shot from three sides at once.

04What Mirror King is weak to

Mirror King is Human. Elements that work well against it: Shadow (×1.6), and every other element deals normal damage. It resists nothing.

Heroes with these skills have the edge (skills are drawn at random on level up, so grab these when they show up):

  • Necromancer: Skeletal Mage, Corpse Explosion, Soul Rain, Decrepify, Life Tap, Curse
  • Assassin: Shadow Step, Mind Blast, Smoke Bomb, Phantom Blades

For the full chart, see Beginner's Guide: Element Chart.

05Tips

  • Clear reflections first: they have only 8% of his health and die to a passing sweep. Leave them be and you have two extra guns chasing you.
  • When he vanishes, sidestep: right after a blink he fires a fan of bullets, and standing still means eating all of them.
  • Ruin corridors are narrow: the walkways between pillars are easy for him to block with a blink, so fight in open areas when you can.
  • Bring Shadow skills: he's Human, so Shadow deals ×1.6 and every other element deals normal damage.

06The Mirror King in chapter four of the story

The first time you enter the Forgotten Ruins on Normal, solo, before Sable has joined your town, you play chapter four of the story, "Shadows in the Ruins". At 3:30 you meet Sable the assassin at the temple of the seal, and she mistakes you for a mirror reflection and duels you first. Then you have to turn three mirrors to guide sunlight onto the temple door for 15 seconds straight before it opens. Until the temple opens, the clock stops at 7:59.

In this chapter the Mirror King splits into four: first about 8 seconds after appearing, then roughly every 20 seconds. The four figures surround you, stand still and have identical health bars, but only the real one casts a shadow. About 4 seconds after the split, Sable marks the real one with a red line. Hitting a reflection hurts you (about 1.2% of your max health per hit). The reflections can't be destroyed; after 8 seconds they shatter into crystal on their own, each firing five shards at you.

Shadow Blade… I have searched for you in every mirror of these ruins. Give me the key.

Sable

Careful: he splits into reflections. Only the real one has a shadow. Striking a reflection hurts you. I'll mark him for you.

Sable follows you and fights with five Assassin skills: Stab, Blade Fury, Lightning Sentry, Phantom Blades, Fire Bomb. She has twice your max health, and every few seconds she slips behind the strongest enemy to stab it in the back. Beat the Mirror King and step into the portal, and Sable joins your town; from then on you can switch to the Assassin at the campfire.

07Other bosses in Forgotten Ruins

The 3:00 mid-boss is drawn from Necromancer, Grisbon, Skeleton Lord; the 6:00 one from Grisbon, Skeleton Lord (never the same as the 3:00 one).They also enrage at half health, and each one drops a piece of gear.
