Reforging
Sometimes you find valuable items like powerful gear and sometimes you will get less attractive rewards from a successful adventure. Be it low level gear that is not worth wearing anymore or literal "trash" items.
When you reforge items there are a few things to know:
Only item level matters for the item level of the result
Result is only based on the reforge materials item level. So when reforging 5 low item level materials you won't get high item level result.
Base chance of reforging to be successful is 50% when only using trash items.
You can increase the chance of successful reforging by including non-trash items into the used materials. The higher an items quality is (border color) the higher the increase in chance of success:
Quality Border Color Success Chance Trash Grey 50.00 % Normal Red 75.00 % Rare Green 83.33 % Mystic Blue 87.50 %
