I don't know if there is already such a kind of topic. However I have start this when a quest-giver gave you something exceptional as a reward.

Well, today I will say thank you to Maleria. She gave me a spectrum potion.

Yesterday Major Drills gave me a retired item not found on the shop search. I put it in my holiday gallery. Thanks, Drills!

Congrats on the potion, btw!
