I like the nostalgia from old school Tibia when these things were still a big deal: Wand of Inferno, Fire Sword, Demon Set
I also think Eternal Flames are pretty cool.
Molten Plate is a pretty epic rare but it's quite expensive.
Apart from regular items you could get a Dragon Corpse if you live in a house that it can be pushed to. Venore = Possible, Yalahar = Not Possible etc.
Note that the Dragon Corpse needs to be spawned after server save. Corpses from dragons that you kill decays in the house.
