Frenzied Berserker

Description
The random madness of the thunderstorm and the unpredictability of the slaadi come together in the soul of the frenzied berserker. Unlike most other characters, they do not fight to achieve a heroic goal or defeat a loathsome villain. Those are mere excuses -- it is the thrill of combat that draws them. For the frenzied berserker, the insanity of battle is like an addictive drug -- they must constantly seek out more conflict to feed their craving for battle. Because of their traditional love for battle, Barbarians are the ones who most frequently adopt this prestige class. Spellcasting characters almost never become frenzied berserkers.

Requirements
Base Attack Bonus: +6

Alignment: Any non-lawful

Feats: Cleave, Great Cleave, Power Attack

Toughness
At 1st-level the Frenzied Berserker gains Toughness as a bonus feat.

Frenzy
A 1st-level Frenzied Berserker gains the ability to frenzy. Frenzy adds a +6 bonus to Strength (no Constitution bonus), imposes a -4 penalty to AC, and gives the Frenzied Berserker a single extra attack at their highest Base Attack Bonus (this does not stack with haste or other effects that add an additional attack). Each round of the frenzy, the frenzied berserker takes 6 points of damage (12 in the unpatched game). The effects last 3 + Constitution modifier rounds (Extend Rage feat extends the duration by 5 rounds), after which the frenzied berserker is fatigued for 5 rounds, suffering -2 Strength, -2 Dexterity, and -10% movement penalties. Initially, this ability can be used once per day and at 3rd level and every odd level after that, the frenzied berserker gains an additional use per day. Bonuses and penalties (including fatigue effects) from Frenzy and Barbarian Rage stack with each other. Frenzy bonuses do not stack with any +strength items or magic you have equipped/cast.

Frenzy can be instantly activated.

Supreme Cleave
At 2nd level, whenever the Frenzied Berserker drops an opponent in melee, they gain two cleave attacks against an adjacent foe instead of one.

Deathless Frenzy
At 4th level, when the Frenzied Berserker is under the effects of Frenzy, he/she has the effects of the 4th level Cleric spell Death Ward. For the duration of the Frenzy, the Frenzied Berserker is immune to any Energy Drain, Negative Energy Damage, Ability Decreasing Effects or Death Spells, Spell-like Abilities, and Effects. This bonus is in additon to all benefits and penalties granted by Frenzy itself.

Enhanced Power Attack
At 5th level, the Frenzied Berserker gains a +5 damage bonus (instead of +3) using the Power Attack feat. Using the Improved Power Attack feat, the Frenzied Berserker gains a +10 damage bonus (instead of +6). This translates to +10 with two-handed weapons for standard Power Attack and +20 for Improved Power Attack.

Inspire Frenzy
At 6th level, the Frenzied Berserker can inspire a Frenzy in all his/her allies. This ability only affects the Berserker's allies. Inspire Frenzy grants a bonus identical to the Frenzied Berserker's Frenzy except that it lasts for 2 rounds (insead of 3 + Constitution Modifier rounds), applies Fatigue penalties for 2 rounds afterwards (instead of 5 rounds), and that the bonuses from Inspire Frenzy and Barbarian Rage do not stack (penalties still accrue). The Frenzied Berserker can use this ability once per day at 6th level, twice per day at 8th level, and three times per day at 10th level.

Greater Frenzy
At 8th level, the Frenzied Berserker gains a +10 bonus to Strength while under Frenzy instead of a +6. The Frenzied Berserker retains the additional extra attack at highest attack bonus as well as the -4 penalty to AC. The Berserker continues to take 6 damage per round of Frenzy (12 in unpatched game), and is still fatigued for 5 rounds afterwards (-2 Strength, -2 Dexterity, -10% Movement Speed). The effects of Greater Frenzy stack with all effects of Barbarian Rage (including Fatigue), though there is a +12 cap on bonuses to Ability Scores.

Note: the NWN2 class description wrongly states this ability is acquired at 7th level.

Supreme Power Attack
A 10th level, the Frenzied Berserker gains a +6 damage bonus (instead of +3) using the Power Attack feat. Using the Improved Power Attack feat, the Frenzied Berserker gains a +12 damage bonus (instead of +6). This translates to +12 with two-handed weapons for standard Power Attack and +24 for Improved Power Attack. This replaces the bonus granted by Enhanced Power Attack.
