I heard in game (HOA) that gear stats will always be the same once ***forged regardless of quality. But your appraisal tool use the gear's drop stats as the base instead of the gear's base/official stats. That mean the gear's quality affect the end result, which is unlike what I heard in game. I'm so confused.
This isn't always the case. It works with the Mighty Mimic Head because its stats are negative, and at high quality, the negative stats become higher. Furthermore, if you level it up to level 13, the bonuses will be maximum for any quality. But this only applies to bonuses (and not to all). For example, if you want a ward, you'd need to get the ornate and level it up to level 13 to get the maximum.
Check out the appraiser on the website for different items. Everything is displayed here just like in the game.
Hello. No. Item level and quality are constantly changing. But it doesn't always make sense to aim for the ornate quality. For example, if you take a Mighty Mimic Head, the best quality is quality Broken and level 13.
