Trailing streaks of cinders race outwards to form a glowing symbol starting at a point you choose within range. The symbol is a 50 foot diameter circle. As part of casting this spell you may hold the ignition until the beginning of your next turn or ignite it immediately to summon forth the chaotic incarnation of explosive power in the form of a massive pillar of fire dealing 12d12 fire damage to any creature in range. The column of fire is 300 feet tall and 50 feet wide. Any creature can make a dexterity saving throw for half damage.

If a creature couldn't make it out of the spells radius with its current movement speed it has disadvantage on its saving throw.

The fire spreads around corners. All flammable objects that are not being used or worn are incinerated and turned to ash sending massive plumes of smoke into the sky.

After a creature takes damage from this spell they are vulnerable to fire damage until the end of your next turn.
