You can only unlock the armor during Mogloween/Halloween (and use outside Mogloween with the Armor Closet).
I played dragonfable for 3 years! Pumpking armor are very easy to have. Do the quest. Is before the pumpking armor. Good luck!

Waffles hello how to get a free armor
When its Halloween
it is xxarmorxx
first of all it is called pumpkin lord armor, and you can only get it during mogloween or using a dragonfable trainer class loader
If you have an Adventurequest account as a guardian. Then just verify it on Dragonfable
You have to order it online
the strongest armor in dragonfable is the doom knight armor, but if you are a DA owner, you can purchase 1, but you need to have the DA for 6-24 months.
You can buy armor,get specicil armor, do a bomb run, and they will be quest soon.
you have to get a undead slayer badge from Artix
you can get technomancer armor which is awsome.
