Conflagrate

At will, conjure a sigil above the enemy you have chosen. After a brief delay, the target erupts into spellfire, taking 2d8 damage. However, at the beginning of a burning target's turn, the flames attempt to spread to all nearby units within a 10 foot radius. Affected units, excluding yourself, must make a Dexterity saving throw or catch aflame and take 2d8 damage. The caster of the spell may receive the flame but take no damage. This can spread back to the original target and lasts a maximum of 5 turns including the first.

When cast at a level higher than 4th level, this spell gains 1d8 damage and lasts an additional turn for each additional level.
