Hi what exactly is a reward from that quest? Is there anything special about that "bead"? It has the same description as regular bead that drops all the time from the moobs, just slightly different icon? Screen for reference:
You get one WT/SCM marble. Not particularly. No. It is the exact same marble drop you get from mobs in WT/SCM dungeons.
So the quest is basicaly do the dungeon 250+ times (and have ~1000 marbles in depo already) to get one more marble? ; wut
Very useful quest for SRS marble though. SRS marble is rare drop and useful to craft the SRS ornament compare to SCM marlbe that only used to craft untradeable cloth, weapon & useless ornament.
