We have been running multiple "sentinel chain" quest since 2 days and the scroll counts is way above average, from memory 2 midnights greetings, 6-7 chimera fang, 4-5 chimera crown, 1 "monk bracer ones", 1 winters wrath and maybe 1-2 more.
NO SHARDS... NO SEALS!
Any modification they made or known bug?
