is the damage dealt through any given item or weapon when using its ability.

Increasing Base Magic Damage
The skill increases  by 0.5% per level, up to 30% at level 60. Increasing base can also increase magic damage. Base from Enchanting is rounded up in the player's stat summary.

Increasing Ability Damage Stat
Some gear provides such as Dark Goggles, Shadow Goggles, and Wither Goggles. can also be further increased with the Renowned reforge, the Loving reforge, the Sheep Pet, and Legion.

With 60, a Sheep Pet with Minos Relic, 5 star Wither Goggles and a 5 star Hyperion with, and a chestplate with the Loving Reforge, your ability damage will increase to 193.3 inside dungeons, essentially meaning any magic damage you do with the weapon will do around three times as much damage as with zero. Although the magic damage can be increased further by using a Superior Dragon Chestplate, Leggings and Boots, as well as the Renowned reforge on the Helmet, Leggings, and Boots, it is often not worth it as you sacrifice a lot of for not too much , which leads to dealing less damage.

Formula
$$\text{Magic Damage} = (\text{Base Magic Damage}) \times (1+ \text{Ability Damage Stat}) \times \left(1+ (\frac{Intelligence}{100}) \times \text{Ability Scaling}\right)$$

Note that Magic Damage can be increased by other multipliers such as Combat Level. See table below for ability scaling.
