Corona Burst

Hurl a unique bomb at an enemy, covering the adjacent area, a cone area (15 ft), and a linear area behind the enemy (15 ft) dealing 2d8 (+ Wisdom Modifier) damage to each enemy hit.  If you have gone down the Immanis tree, you can choose which debuff (of the three) to apply to the enemy (slow, static, DoT).  

When cast at higher levels, the damage increases to Xd8 (+ Wisdom Modifier) damage, where X = the level of spell slot used to cast the spell.  A 3rd level, you can apply two debuffs and at 4th level all three can be applied.
