Upgrading Equipment
In Elsword Weapons and Armor (Top, Bottom, Shoes and Gloves) can be upgraded. By default they start without upgrades, and as you upgrade they become +1, +2, +3 up to +11.
To upgrade equipment, you need to talk to any blacksmith NPC (indicated by the sword icon in town). You will need a certain item and some money in order to upgrade.
