Boss Mechanics and Evasion

To survive Guardian difficulties, you must understand specific boss attack patterns and evasion strategies. Relying on disorganized dodging will result in rapid deaths.

IRIS (Final Boss)​

IRIS is the final boss and features a notoriously difficult two-phase fight.

Phase 2 Strategies​

The second phase generates immense visual clutter. You must navigate a combination of massive area-of-effect (AoE) damage, homing projectiles, and static laser grids known as Security Doors.

  • Read the Telegraphs: Learn to recognize the specific wind-up animations for each attack.
  • Manage the Security Doors: Maintain strict situational awareness of the static laser grids. Frantic, unstructured evasion will often result in you trapping yourself against a laser grid while trying to dodge a projectile.
  • Build Optimization: High single-target burst damage builds are vastly superior to room-clearing builds for this encounter. You need to end the phases quickly before the visual clutter overwhelms you.

The Catercoaster​

The Catercoaster is a mid-game boss that requires a structured approach. Instead of treating this as a chaotic damage race, break down its specific moveset:

  • Tripmine Trap: Deploys mines behind it directly onto the rail. Do not follow it too closely.
  • Turret Toss: Launches capsules that spawn stationary laser turrets. Destroy these turrets immediately to reduce incoming crossfire.
  • Rocket Barrage: Fires a volley of homing missiles. Use slides or cover to break line of sight.
  • Accelerate!: A high-impact charge attack. Watch for the visual and audio cues and prepare to make a sharp evasive maneuver.
