Every item is at Level 1 by default. After each successful enchantment, the equipment will be increased by 1 level and of course, becomes much stronger. Each time enchantment the item increases by 1 level for each successful enchantment. The number of gems needed for enchantment is equal to the level to be increased. The higher the level, the lower the success rate. Each time the enchantment fails, the player will lose all of the gems used. Note that from level 12 and above, each failed enchantment will cause the weapon to drop by 1 level. For example, if the equipment is at level 12, the player enchants to level 13 and fails, the weapon will be downgraded to level 11. The highest possible level is 16 for all items.
