Defeat The Alchemist of the Bastille in Steelrising with this detailed boss guide, focusing on elemental weaknesses.
Location: Bastille, within the hidden workshop.

This boss is an elemental specialist, utilizing fire, frost, and fulmination attacks. It's a test of your elemental resistance and ability to manage multiple elemental threats simultaneously.
Phase 1: Elemental Barrage
- Attacks:
- Flamethrower Arm: Sweeps a cone of fire, applying Ignition.
- Frost Cannon Arm: Fires a burst of ice, applying Frost.
- Elemental Drones: Summons small drones that explode with a specific element.
- Ground Slam: A localized ground slam that deals physical damage.
- Strategy: Stay mobile and keep your distance when it's using its elemental arms. Focus on one arm at a time to temporarily disable that elemental attack. When drones appear, prioritize them to prevent being overwhelmed by status effects. Dodge into its ground slam to get behind it.
- Weakness: Highly vulnerable to Fulmination. Use Fulmination Grenades or Fulmination-infused weapons to stun it, interrupting its elemental attacks and creating large openings.
Phase 2: Enraged Alchemist (approx. 50% Health)
- New Attacks:
- Elemental AoE: Unleashes powerful area-of-effect attacks, covering large portions of the arena in fire, ice, or lightning.
- Lunge Attack: A fast, forward lunge that deals significant physical damage.
- Enhanced Drones: Summons more drones, or drones with higher health/damage.
- Strategy: The key here is recognizing the wind-up for its AoE attacks. There will be visual cues on the ground indicating the affected area; move out of these zones immediately. Continue to exploit its Fulmination weakness to interrupt its most dangerous attacks. The lunge attack is fast, so a quick side-dodge is necessary. Be patient and only attack when you have a clear opening after its combos or during a stun.
Rewards:
- Anima Essence: ~8,000-12,000.
- Alchemist's Module: A unique module that often provides elemental resistance or an elemental damage bonus.
- Key Item: Information or a key to Vaucanson's location.
General Tips: Consider equipping armor with balanced elemental resistances. Stock up on Fulmination Grenades. Don't be afraid to use your Alchemical Capsules to heal through damage over time from Ignition or Frost. Prioritize dodging over blocking for most of its attacks.
