Reforge cost
The 
Goblin Tinkerer reforges an item for one third of its current value (times the stack). That value includes the prefix, so a better prefix makes the next reforge cost more.
With a 
Discount Card or a 
Greedy Ring equipped, reforging costs 20% less.
The happiness of the Goblin Tinkerer multiplies the cost by 0.75 to 1.5.
A reforge never gives no prefix.
