Blazing Focus

You set your arcane focus ablaze and throw it forward in a 100 foot line. Each creature in the line must make a Dexterity saving throw. A creature takes damage depending on the type of focus you have on a failed save, or half as much damage on a successful one.

• Crystal: 1d4 fire damage.
• Orb: 2d10 fire damage.
• Rod: 2d6 fire damage.
• Staff: 3d10 fire damage.
• Wand: 1d6 fire damage.

Once your focus travels 100 feet, it returns to you, but does not hit any creatures the second time. If your focus hits a wall, it also returns to you.

If you have chosen a custom arcane focus, work with your DM to determine the size of it relative to the default choices. Your damage is determined as such.
