Maniac is a rune effect in Frenzy, a Fury-generating Barbarian skill.

This rune effect increases the Barbarian's damage by 4% with each strike of Frenzy. This is not a general buff -- unlike the Punish rune effect in Bash -- the 4% damage does not apply to other skills. Only to the hits with Frenzy. As Frenzy is already the highest DPS Barbarian skill to a single target, this rune is very effective to chew the life off of large targets.
