Retaliate (Berserker)

 is an active skill that that can be learned by Berserkers at level 12 and can be ranked up.

can be performed with an axe by the Berserker to quickly stand back up and deal damage in the process. However, the cooldown is relatively long, so save it for when you really need it (ie. the opponent is really near).

Amount of damage dealt varies dependent on skill rank.

Rank table
To upgrade to the next rank, one must find a Tactics 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 berserker glyphs. Most glyphs, specifically common glyphs can be purchased from a Glyph Master, while fine glyphs must be looted from enemies.
