LoSH is sweet, but the final spawn in the outpost is rare. I got mine when my guild found him up. The tank said he had waited over 3 months to find the spawn up, and that was checking every day.
If you have DON the Shield of the Silver Serpent is a common drop. (Sorry I dont do links at work.)
Jonwin is actually using a Muramite shield that he picked up and Winjon is using a Tae Ew Shield.
