Arcing Hallway

This stone hallway ends in a large statue.

Magical Trap

The statue is the image of a thunder god and holds lightning bolts in his hands.  A DC 14 Intelligence (Religion) check reveals lightning is part of the holy ritual to the god, and those that revere the god can be struck by lightning without harm. When a target gets within 5′ of the image, lightning fills the hallway starting 30′ away from the statue. This lasts for one hour. Those that move through the lightning take 6d6 electricity damage per 30′ of movement. A DC 16 Dexterity (Acrobatics) check halves this damage. If a prayer is offered to the god targets gain advantage on one attack roll of their choice in the next 24 hours. A successful prayer requires a DC 16 Intelligence (Religion) check. A detect magic detects an aura of evocation on the statue. A dispel magic has no effect. Only a hallow spell will dispel the effect for one hour.
