Instant Barricade

Spell Lists: Artificer
Level 3 Conjuration
Casting Time: 1 Action
Range: 60 ft.
Components: V, S
Duration: 10 minutes

You create a barricade, no larger than a 10-foot Cube, in an unoccupied space within range, which remains fixed in place for the duration or until it is destroyed. You decide the appearance of the barricade, including its size, shape, and whether it is opaque or transparent. Regardless of your choices, it uses the Instant Barricade stat block.

Instant Barricade

Object of varying size
AC: 12 + the spell’s level
HP: 10 times the spell’s level
Immunities: Poison, Psychic

Explosive Disassembly: If the barricade is reduced to 0 Hit Points, each creature within 5 feet of it must succeed on a Dexterity saving throw or take Force damage. The damage is a number of d6s equal to the spell’s level. The space previously occupied by the barricade then becomes Difficult Terrain for the remainder of the spell’s duration.

 Using a Higher-Level Spell Slot: Use the spell slot’s level for the spell’s level in the stat block. The size of the Cube also increases by 5 feet for each spell slot level above 3.
