Here's how I did my fury:
Dark Channel 6 (Damage, Recharge, Pierce)
Annihilation Field 6 (Damage, Damage, Damage)
Throw 5 (Force, Detonate)
Fury 5 (Power damage, Power Damage)
Fitness 3

I think that's right... hard to remember. I only built her once, liked it so much I haven't respec'd or promoted.

She's like a machine gun with explosions, especailly with someone else to detonate with. The Annihilation field is great for damaging anything that gets close and sets up for a mean explosion.
