Athen's Flashstrike

As part of the action used to cast this spell, you must make a melee attack with a weapon against one creature within the spell’s range, otherwise, the spell fails. On a hit, the target suffers the attack’s normal effects, and a luminous blade pierces through the target striking out in a 5-foot-wide, 10-foot-long line. The first creature in this line takes 1d6 radiant damage + your spellcasting ability modifier, and the spell ends.

If this spell is cast within 5-feet of the target the blade strikes out in a 5-foot-wide, 20-foot-long line instead. Each creature in this line must succeed on a Constitution saving throw or take 1d6 radiant damage + your spellcasting ability modifier, and the spell ends.

The spell prompts more than one attack when you reach higher levels: two attacks at 5th level, three attacks at 11th level, and four attacks at 17th level. Make a separate attack roll for each.
