When you successfully upgrade, you gain following effects:
Weapon Lv. 1 - Every +1 upgrade gives +2 ATK
Weapon Lv. 2 - Every +1 upgrade gives +3 ATK
Weapon Lv. 3 - Every +1 upgrade gives +5 ATK
Weapon Lv. 4 - Every +1 upgrade gives +7 ATK
Every +1 upgrade gives +1 (it's actually only 0.66) Equipment DEF (not VIT DEF).
Upgrades are useful, as for weapon upgrade, it reduces damage range between min - max damage (allowing you to do better average damage), it also increases your damage range. For armors, it reduces damage you take by 0.66%(for checking) per every upgrade level.
Upgrading failure means your equipment will be permanently destroyed, including any cards and other enchantments it may have had. You won't be refunded Zeny and the ore used to upgrade if it fails. Give careful thought before deciding if you want to upgrade a piece of equipment.
