I do have a save game from before entering the Vault... shoot me a PM with your email and I'll send it to you.
Interesting technique. I hadn't thought about summoning elementals... that probably would have made the Jester Spawn in the previous part of the vault a lot easier...
Off to finish Colony Zod tonight. Hasted blaster rifles should be really, really nice on all those Titans. Heck, maybe I'll even go clean out the Titan Fortress too... just snuck in for the Perfect Bow earlier.
