In my build i decided to put 5 attack :

1) sonic arrow (crippling challenge + deadly dissonance)
2) Force cascade (rank3)
3) Orbital Cannon (rank2 + anvil)
4) force eruption (gravitational)
5) ?????????

I have electrocute as hold.

For the 5th i was thinking to put or Gigabolt rank3 for pve and better tap than FC or Gauntlet chainsaw or lighting arc with the advantage but i'm not sure.

I yet have miniatur drive but i don't have sonic device and toxic nanites.

I'm SS int-rec

i'm trying many powers and at the moment there are few powers that i like and that are ok for the build:

- Rocket launcher rank2 with the adv to knock
- gauntlet chainsaw (that can be replaced with 2 charged FC if i can cast them.......)
- ice burst with the adv(but i have yet a hold so i don't know.....)

HELP please someone that have an idea.
