Fire Mastery

The 5-piece set bonus of "Trang-Oul's Avatar" grants a lvl 3

Fire Mastery Oskill.

Oskills can be used by any class, but the skill level bonus is limited to 3 levels for the native class. Oskill levels can be increased like native skill levels, including "+skill (native class only)" bonuses.

The elemental damage bonus stacks additively, not multiplicatively with the one provided by items (such as Rainbow Facet or

Eschuta's Temper), somewhat diminishing their usability for a Sorceress.

This skill increases the damage of all skills in the Sorceress's Fire skill tree. Furthermore, it increases the fire damage component of a Sorceress's Attacks, whether that damage comes from a socketed

Ruby,

Ral, or Jewel; from

Enchant or

Holy Fire; or from any other modifier on the Sorceress's equipment.

One consequence of this functionality is that

Fire Mastery will effectively apply to the Sorceress's

Enchant-augmented attacks twice - first upon casting, and second upon Attack.
