Cinder Instinct

You awaken a primal survival instinct within a creature, flooding its senses with the imminent certainty of spreading flame and consuming heat.

One creature you can see within range must succeed on a Wisdom saving throw or take 3d6 fire damage and immediately use its reaction, if available, to move up to its speed in a direction of its choice that leads away from you. This movement is considered voluntary and provokes opportunity attacks as normal.  

A creature that succeeds on its saving throw takes half as much damage and does not move.

A creature with resistance to fire damage has advantage on this saving throw. A creature with immunity to fire damage automatically succeeds on this saving throw.

Using a Higher-Level Spell Slot. When you cast this spell using a spell slot of 2nd level or higher, the damage increases by 1d6 for each slot level above 1st.
