Raddik’s Focusing Blast (5e Spell)
From D&D Wiki
|Casting time:||1 action|
|Duration:||Concentration, up to 1 minute|
Choose a 60 foot radius sphere within range. Everything within that range must make a Constitution Saving Throw or take 3d8 fire and 3d8 lightning damage, or half as much on a success.
If you are still concentrating on the spell, on your next turn, you can use your action to focus the blast. Choose a sphere within the previous blast’s range, with half the range(rounded to the nearest 5) of that blast. This deals the same damage as the last blast, with an additional 1d8 fire and 1d8 lightning damage. You can do this twice, and after the third blast, you lose concentration.
At Higher Levels. When you cast this spell using a spell slot of 7th level or higher, increase the initial radius by 10 feet, and increase the scaling damage by 1d8 fire or lightning damage(your choice), by every level above 6th.
