Power Creation; need a bit of help.

[Bluedisc]

Right now I am trying to re-create Kira Yoshikage's Primary Bomb

 

I've almost got done adding the script that turns people into ash when they die, but I still can't find out;

 

How do I add a explosion to somebody without a projectile?

I've come across nothing that explains this, and seriously need someone to help.

 

Here's how I plan for everything to go.

 

Use Power On NPC/Actor > Glows for half a second > Explosion > While explosion happens, ash pile spawns. > Explosion disappears, ash pile is on the ground where the NPC/Actor was.
