Blade Barrier

← Back to Spell List

Blade Barrier
  • Level: 6
  • School: Evocation
  • Class: Cleric
  • Casting Time: Action
  • Range: 90 feet
  • Components: V, S
  • Duration: Concentration, up to 10 minutes

You create a wall of whirling blades made of magical energy. The wall appears within range and lasts for the duration. You make a straight wall up to 100 feet long, 20 feet high, and 5 feet thick, or a ringed wall up to 60 feet in diameter, 20 feet high, and 5 feet thick. The wall provides Three-Quarters Cover, and its space is Difficult Terrain.

Any creature in the wall's space makes a Dexterity saving throw, taking 6d10 Force damage on a failed save or half as much damage on a successful one. A creature also makes that save if it enters the wall's space or ends its turn there. A creature makes that save only once per turn.

Creator Notes

Adjudication Guidance:

  • Wall can be shaped as straight line or complete ring
  • Three-quarters cover provides +5 AC and Dexterity save bonuses
  • Difficult terrain in wall space slows movement but doesn't prevent it
  • 6d10 Force damage significant threat but allows save for half

Encounter Design Considerations:

  • Dramatically alters battlefield geography for entire encounter
  • 10-minute duration covers multiple encounters if needed
  • Forces tactical decisions about positioning and movement
  • NPCs should respect the wall's danger and adjust tactics accordingly

Balancing Notes:

  • 6th-level slot cost appropriate for powerful battlefield control
  • Concentration requirement creates vulnerability for caster
  • Force damage rarely resisted but Dexterity saves allow counterplay
  • Large area coverage balanced by single-wall limitation

Environmental Interactions

Physical Properties:

  • Wall of spinning blades creates both visual and auditory presence
  • Provides substantial cover but doesn't block all line of sight
  • May interfere with environmental features like doors or windows
  • Creates wind effects from spinning blade motion

Terrain Integration:

  • Can conform to ground level but doesn't follow slopes exactly
  • May partially embed in walls or other solid barriers
  • Height allows most Medium creatures to pass underneath in some circumstances
  • Thickness creates zone of danger rather than simple barrier

Interaction with Objects:

  • Destroys most objects that come into contact with blades
  • May damage or destroy environmental features within wall space
  • Ammunition passing through takes damage and may be destroyed
  • Living walls, plants, or organic barriers suffer significant damage

Narrative Flavor

Extended Description: You raise your hands skyward while speaking a prayer that resonates with divine authority and righteous fury. The air around your target location begins to shimmer and hum with building energy, and suddenly erupts into a magnificent wall of spinning, gleaming blades. Each blade appears to be forged from pure divine energy, rotating and spinning in perfect patterns that create an impenetrable barrier of righteous steel. The wall pulses with holy power, its blades singing hymns of protection and justice as they slice through the air with lethal precision.

Sensory Details:

  • Visual: Gleaming blades of divine energy spinning in perfect formation
  • Auditory: Harmonic singing of spinning blades and divine hymns
  • Spiritual: Overwhelming sense of divine justice and protection
  • Kinesthetic: Wind and pressure from spinning blade motion

Cultural Context: Blade Barrier represents the divine's capacity for both protection and righteous violence, creating barriers that defend the faithful while threatening those who would bring harm. Different religious traditions may manifest this differently—some as angelic weapons, others as divine justice made manifest—but all emphasize the protective and martial aspects of divine power.
