How to get torpedo spread 3?
 

i got the torpedo spread 2 but does anyone know how to get the torpedo spread 3?

only place i've seen to get it reliably is facility 4028, jem'hadar boff end reward.

states it's very rare and may be found on uncommon and higher boffs. jem'hadar is a sure thing though.

^ He speaks the truth. Just do that mission on normal, easy win, and then take your BOff and it's TS3.

The other option is about a mil at the exchange. I'd do the mission personally.
