The Felguard's damaging melee attacks cause a demonic frenzy, increasing attack power by 5% for 10 sec. This effect can stack up to 10 times.
Demonic Frenzy is a passive self buff for your Felguard.
This ability does not proc if the target does not take damage. For example: if the target blocks, dodges, parries, is bubbled, etc., the Felguard will not gain another stack of Demonic Frenzy. It is learned automatically with Level 56.
Demonic Brutality - Increases the effectiveness of each stack by 1/2/3% per talent point.
