Description: The caster creates a small, magical zone that can detect the passage of enemy creatures. When the field is activated, it explodes, doing 1d6 points of Fire damage per caster level to all within the area of effect, boosted by Lore, with no cap. If the fireball remains set for at least one round, it receives +3 Spell Penetration per focus feat in Abjuration.
The unstable nature of this spell will cause it to decay over time. This can also be caused by close proximity to other delayed blast fireballs.
Notes
When cast by a Bloodfire Mage, this spell does an additional 1d6 Positive damage per 2 Caster Levels.
This spell does not function underwater.
