How to unlock the You're En Good Hance achievement in Record of Agarest War Zero - Definitive Guide
However, the silver lining is that each enhancement on an item counts as one, therefore fully enhancing 1,250 items to their max level of 5 will net you this achievement. Converting an item does not count as a 5th enhance per item.
Also, there are enhancement titles in the game that will keep track of this achievement for you UP TO 2000. After that, you must keep a running tally yourself unless you just want to leave it to chance at how far you are or must go. Good Luck!
To enhance an item you must go the Blacksmith select Enhance. There will be an enhance abar next to every weapon, armor, accessory and skill's attached to your armor/accessories. Every time you enhance a bar it counts towards the 5000 count, so you could enhance a level 1 item to level 5 right away and it will count as an enhance 4 times. But by this logic that means you will have to fully enhance 1250 items to level 5. Ideally you could purchase 99 low level items in the shop and enhance them over and over again until you obtain your trophy, it is highly unlikely that you will unlock this "naturally".
The only way to track the amount of enhances you have is through a rough estimate from the title(s) 46-51.
