The Chantry would like an enterprising and well-traveled adventurer to collect nine samples of corpse gall. If, by chance, the aforementioned adventurer should find themselves so lucky as to have an abundance of corpse gall, the Chantry will gladly pay extra for them.
Once the desired amount of corpse gall has been obtained, return to any Chantry representative for a reward.
5 for 18 samples of corpse gall, 3 for 9 samples.
Note: If you talk to a Chantry representative while this quest is active and you have more than 9 samples (to complete other quests for example), you will automatically complete this quest. Simply do not accept the quest until you have more than 18 samples, or avoid speaking to a Chantry representative with less than 18 samples, to get the higher reward.
