Yes, you have to make quest, but it's easier :
Changes to Supplier of Reagents quest (Erica 30x server only).
Now at mixing reagents using one of this options you get:
- Degree 1 (Salamander) - 2 products with 100% success (was 1, 100%),
- Degree 2 (Ifrit) - 4 products with 66% success (was 3, 33%),
- Degree 3 (Phoenix) - 6 products with 40% of success (was 5, 20%).

Quest for stack sub :
Quest monster : Ancient Warlord
Quest item : Ancient Torch
Each party member will have chance of 90% to get the quest item (of course if he has a quest, is level 78, and doesn't have a subclass, or Ancient Torch yet).
