Calling on the power of the waves and entreating the rage of primal Elementals of Water, you summon forth a crashing magical tsunami that destroys anything in its path.
The affected area can be up to 1000 feet wide, 1 mile long, and is hit with a wave reaching 100 feet high moving at incredible speed. Buildings, bridges and other physical constructs are destroyed, or their structural integrity compromised by the flood.
Each creature in that area must make a Constitution saving throw. On a failure, a creature takes 20D8 damage and is carried away with the Doomtide. On a success, a creature takes half as much damage and manages to stand their ground. The damage caused by the Doomtide is both bludgeoning and magical in nature.
The water then spreads out across the ground in all direction.
Doomtide must be summoned on a coastal region. The amount of water necessary for the spell cannot come from a harbor or inland source.
