The gift of vampirism enhances not just the physical and mental attributes, but also the emotional ones. By utilising this power, you are able to focus your inner rage into a concentrated fury, gaining a +5 bonus to Attack, Defence, Damage and Speed for each rank you have in this power. The rage lasts 30 seconds, and also negates all pain penalties while active.
Unfortunately this power will also leave the vampire slightly weakened for a while afterwards, but in the heat of battle it is often considered worth the cost. For 30 seconds after the rage has finished, you will suffer a penalty of -10 to your Attack, Defence, and Damage, and -5 to your Speed.
If you also have the Berserker Rage talent, then the bonuses from that will be applied at the same time as your Rage of the Beast, although this power will be used to determine the duration. If you have the Tireless Rage talent, then it will also negate the exhaustion penalties for this power.
