Power Feats

Explosive Blast
You possess the ability to cause an explosive effect at a distance. When you designate an area, you roll to attack the area (effective Def 10), or to center the effect on a person or object, you roll a ranged touch attack.
Prerequisite: 4 power points in a blast power.
Effect: When you designate an area or creature, you make an attack roll (ranged touch attack) and your blast fires toward the target. If your attack roll misses, then the blast goes until it strikes something, or reaches the end of its range, at which point it explodes, causing damage (and knockback) to creatures or objects within the blast radius.
Alternative: If you use the natural 1 roll is an automatic fail rule, this can cause the character to be stunned for 1 round per 2 power points invested in the power (treat it as the explosion happening centered on the character, and the character has no immunity at that point). The character can make a Fort save (DC 20) to halve the stun duration.
