Sunlight Spear (5e Spell)
From D&D Wiki
|Casting time:||1 action|
|Components:||V, S, M (a tiny gold medal depicting the sun worth at least 5 gp)|
You conjure a javelin of crackling sunlight in your hand and hurl it at a creature or object within range. Make a ranged spell attack against the target. On a hit, the target is wreaked with holy energy, inflicting radiant damage equal to 3d12 + your spellcasting modifier. Hit or miss, the spear then explodes into myriad bolts of electricity. The target and each creature within 10 feet of it must succeed on a Dexterity saving throw or take 3d12 lightning damage. Creatures doused in, standing in, or swimming in water make this saving throw with disadvantage. Creatures that are damaged by this spell and are sensitive to sunlight are treated as if they were in direct sunlight until the beginning of your next turn.
At Higher Levels. When you cast this spell using a spell slot of 6th or higher, the radiant damage increases by 1d12 for every slot level above 5th.
