[@RandomCerebrate]I'm waiting to open it up until after this fight; I'd rather it got resolved before throwing new characters into the mix. 

Given how the Goa'uld use plasma against each other, I'd imagine the shielding would be reasonably effective against it. The only established thing so far with regard to Goa'uld shielding is how concentrated the weapon's energy is. The more concentrated, the more effective.

I'm working on updating the zeroth-post summary and responding to PM's; I should have a post up once that's done.
