Quests

How quests work

1
Accept the quest.

If it lists several prerequisite quests, completing any one of them is enough.
2
Track up to 3 quests.

You can have 15 active quests. Tracking a fourth untracks the oldest one, which stays active.
3
Complete the objective.

What counts depends on the quest type. Abandoning a quest deletes its progress.
4
Turn in the quest.

Your 10th, 20th, 30th, and 50th finished quests unlock the quest achievements. A daily quest counts once, however often you repeat it.

Type	What counts	At turn-in
Kill	Kills after you accept	Nothing is taken
Discover	Reaching the place after you accept	Nothing is taken
Find	Done as soon as you accept	Talk to the completion NPC
Gather	Items you gather after you accept	You need not keep the items
Have	Items, keys, or equipped items you hold, even from before	You keep the items
Deliver	Items you hold, even from before	The items are taken. An equipped required item is taken if inventory has too few. Keys stay.
Equip	Every listed item equipped at once	You keep the items
Brew	Potions you brew after you accept	Nothing is taken
