How to beat Mirren

Single phase. Watch the tell, burrow the wind-up, punish the recovery.

Single Phase — Frostbite Woods ghost

Pattern: A ghost in an abandoned carriage. Her most dangerous attack is cloning herself and diving across the screen.
Tell: She splits into clones before the cross-screen dive.
Counter: When she clones and dives, focus on dodging and burrowing rather than attacking — wait it out, then punish between dives.

Quick tips

·Reach her from the Coltrane Peak: Frostbite Woods Underlab — head right under the ice, dig under it, and use the skull-topped block to let the larger ice chunk recover.
·Tell her you're there to help to trigger the fight.
·Don't trade hits during the clone-dive; survival first.
·Beating her grants the Blinking Glass trinket (random full damage avoidance).
