Somebody help me please. I am trying to get the quests to destroy both gangs in the boil. I talked to Mr. W. and all he told me was talk to Sebastion, so I did, and I got the wine for him, and killed the gang member. But that's it!! W. won't tell me anything else. Isn't there further things to do in this quest?
You can only work for one of the gangs... so I guess to finish the "Tarant" problem, you should just go in the other gang's base and kill all the gang members.
What kcwong said. If Sebastian is in your group, have him wait and go clean house on the remaining gang. There are a few ways to get the fight going. One is to pick the lock on the guarded steel door. This way Magnus doesn't gripe.
