This functions as Improvised Arcane Device except the number of damage and healing dice is doubled. Every spell level spent on damage or healing provides 2d6 + Spell Proficiency instead of 1d6 + Spell Proficiency. So if all 3 levels from a 3rd-level slot are spent on damage, the device will deal 6d6 + (Spell Proficiency × 3) damage. There are also two new effects available.

Effect Types:

Slow: Slows all creatures within 15 ft. for 1 round per spell level spent on slow.

Invisibility: Renders all creatures within 15 ft. invisible for 1 round per spell level spent on invisibility. Direct offensive actions will end the invisibility.

VTT Number of Dice:
