Fireball

 is an active skill that is automatically learned by Sorcerers upon character creation and is able to be ranked up at later levels.

can be performed with a disc by the Sorcerer to deal a minimum amount of damage, often used when the Sorcerer is low on mana as this skill's mana cost is almost nothing. Holding down the left mouse button causes the user to auto-cast Fireball in quick succession.

Amount of damage dealt varies dependent on skill rank.

Rank table
To upgrade to the next rank, one must find a Magic Instructor and pay a certain price of gold dependent on rank.

Glyphs
To glyph, a glyph must be obtained and learned only once. At level 60, a character has 50 glyph points available to spend on all available sorcerer glyphs. Most glyphs, specifically common glyphs can be purchased from a Glyph Master, while fine glyphs must be looted from enemies.
