Tiko's Triumphant Takeoff

A powerful blast of fire bursts forth from your palms blasting you backward. All creatures within the line of fire take 8d6 fire damage and must make a dex save against your spell save dc, taking half damage on a success and full damage on a fail. When you use this spell you fly 20 feet in the opposite direction, falling prone. If you hit a wall you take 1d4 bludgeoning damage but don't fall prone. Aiming the blast downwards changes the range of the spell. If you aim it downwards and it hits the ground, instead of dealing damage in a line, you deal the damage to every creature within 5 feet of you and you get blasted 15 feet upward.
