Well we all know the Alloy-Linked Wristguard, but paging through Allakhazam I found out that it is possible to change the focus effect on it. I am not sure if anybody else has posted this already, and if that is the case just ignore this.
By using the vendor sold bracer container, you can switch the posion focus to a disease focus. As I have 2 bracer this was a true nobrainer. The container is sold for about ~400 pp at the AA Strikeforce V camp.
Apparently you can do this with all SOF T1 bracers, very usefull necros.
If you buy two container, the next step seems to be a chrimatic focus, best for Enc I guess.
