Triumphant Shout (Berserker)

 is an active skill that can be learned by Berserkers at level 10. It cannot be ranked up.

can be performed with an axe by the Berserker mainly to stop mana decay. It is best to use this skill right after exiting combat if you plan to immediately re-enter (ie. you finished killing a mob, and want to kill the one next to it). This is because mana decays as soon as the Berserker leaves combat, and mana has to be slowly earned from performing.

This does not mean that this skill is not useful during combat. In long fights that will last longer than the CD of this skill, this skill is a pretty good way to build up mana outside of using the basic combo attack. It is a good idea to continuously use this skill during those long fights.

is purchased from Tactic Instructors. This skill cannot be upgraded.

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 berserker glyphs. Most glyphs, specifically common glyphs can be purchased from a Glyph Master, while fine glyphs must be looted from enemies.
