Details: (optional)
We killed lei shen with a guild run but i was thrown down cause of fusion slash
so i missed a 100% loot sigil and i kinda want this for legendary questline if possible
Here are some screenshots of lei shen body // guild loot historic (what does the ppl that were with me looted.

We tried to reach the boss body from ra-den chamber but boss was unlootable for me
I also wanted to bonus loot on it as guardian lootspec but couldn't ( for the trinket//pole)
time ~~ half past midnight
Also, i didn't get credit/achiv because i already killed lei-shen in lfr 2 weeks ago

Hope that i'll be able to at least get the sigil
Thanks in advance

Ps: One of my guildies present with me at the raid had the similar problem one week ago, so i've looked at his request 1st

Also, i've read the https://forum.wow-freakz.com/Read-me-IMPORTANT-INFO-t201333.html topic and i didn't found any good // bad case in my situation

EDIT : A proof i've killed lei shen (hope it counts) : http://imgur.com/a/PK8dF
