Is there a "reverse" bard class/ACF?

[RPGaddict28]

I love the idea that a bard plays music so vile, he actually makes his enemies fight worse. Is there an existing class/ACF that handles this?

Look through the ACFs here (http://brilliantgameologists.com/boards/index.php?PHPSESSID=rql0d49tu0ggtfhu0ujcqi4vb4&topic=7908), there's a few, though you usually have to trade out different bits piecemeal. There's also the Doomspeak feat; single target, but it's a pretty hefty penalty.

Dirgesinger comes to mind. PrC from Libris Mortis. Should do exactly what you have in mind.

[OldTrees1]

Jester Base Class [Dragon Compendium]
Weaker than Bard though

[Socratov]

Harbinger (dragon 337)

It has the instill fear class feature (among others) which does exactly the inverse of Inspire courage.

[Urpriest]

Dragon Magic has an Inspire Awe ACF, IIRC, that also helps a debuff-bard.

I thought that let your bard shenanigans buff undead for half bonuses. Or does it do both?

I thought that let your bard shenanigans buff undead for half bonuses. Or does it do both? The requiem feat lets your bardic music abilities effect undead at half-duration, not strength, so it is actually pretty good to have a bard with that feat in an undead army.

Requiem is a requirement for dirgesinger though, which has a series of bardic music abilities that boost undead, and several that cause penalties to the living.

Note that dirgesinger does kind of suck, as it doesn't progress your normal bardic music or spellcasting, which are what make bard T3.

(Savage (http://www.d20srd.org/srd/variant/classes/variantCharacterClasses.htm#bardVariantSavageBard) ) Bard 8/ Nightmare Spinner 1/ Dread Witch 1/ Sublime Chord 2/ Dread Witch 4/ Nightmare Spinner 4. Swap Inspire Courage for Inspire Awe from Dragon Magic, trade Bardic Knowledge for Bardic Knack in PH2, trade Fascinate for Healing Hymn in CC, and replace Countersong with Spellbreaker Song from CM. Every prestige class level after Sublime Chord should advance your Sublime Chord casting, of course. Get those first levels of Dread Witch and Nightmare Spinner asap.

Take two flaws (http://www.d20srd.org/srd/variant/buildingCharacters/characterFlaws.htm), I'd recommend Bravado and City Slicker (http://www.giantitp.com/forums/showthread.php?t=258440#30). Your feats should be Dreadful Wrath (PGtF), Melodic Casting (CM), Fell Frighten Spell (LM), Obtain Familiar (CA), Haunting Melody (ECS), and Improved Familiar (CW). Also say he visited the Otyugh Hole detailed in Complete Scoundrel to get Menacing Demeanor for 3,000 gp instead of spending a feat on it.

Skills, other than prerequisites, should include max ranks in Intimidate, Perform, and Use Magic Device. Definitely get as many skill tricks (CS) as possible, especially Never Outnumbered and Back On Your Feet. Your familiar is a Krenshar, its Scare DC will increase based on your level (10 + 1/2 HD + Cha bonus), and it can make Intimidate checks using your skill ranks.

Get a custom Runestaff (MIC p224) with whatever spells you want on it, you can UMD it at DC 21 to use it as though they were on your own class spell list. Good choices would include Web, Bands of Steel, Black Tentacles, Rope Trick, Command Undead, Kelpstrand, Briar Web, Entangle, etc. You can also include long duration buffs that you don't expect to cast more than once each day to save spells known, such as Greater Resistance, or highly situational spells like Mass Resist Energy.

Get a +1 Mithral Breastplate with the Fearsome property (DotU, +5,000 gp), a Circlet of Rapid Casting (MIC, 15,000 gp), a Mask of the Matriarch (DotU, 9,000 gp), and a Shadow Cloak (DotU, 5,500 gp). Also get some wands of useful low level spells that you can UMD, like Web and Wings of Cover.

You should probably have a pretty good idea of what this character does. Keep in mind that per the Rules Compendium page 53 regarding escalating fear effects, "When such multiple exposures occur, the worst stage of fear lasts until the duration of all the effects causing the fear expire." So your Dreadful Wrath feat causes opponents to save or become Shaken (no action). You can activate Inspire Awe plus Haunting Melody to force opponents to save versus two separate Shaken conditions (standard action). You can use the Demoralize action plus Never Outnumbered once per encounter to cause every opponent within ten feet to become Shaken (move action). You can cast a Fell Frighten Sound Burst to cause anyone who takes damage to be automatically Shaken (standard action, or swift with the circlet). You have many other abilities which inflict a Shaken condition on opponents, plus your Krenshar familiar can activate its racial Scare ability and then use intimidate to demoralize opponents as well. A Shaken opponent who would become Shaken is instead Frightened, a Frightened opponent who would become Shaken is instead Panicked, and a Panicked creature who is prevented from fleeing such as by Web will instead Cower for the duration of the fear or until they can escape. You can buff your party with spells like Haste, crowd control opponents, and be generally useful otherwise. Most of your actions in combat should probably be spent casting spells or demoralizing opponents (two per round as a move action).

There is a Pathfinder Archetype that requires pretty much no conversion called the Court Bard. They pretty much make fun of your mother and debuff the enemies vs buffing you.

Inspire Hate from Exemplars of Evil replaces Inspire Greatness, and makes a person angry at his allies, to the point of violence. My one friend always jokes about it

He f-ed your wiiiiiiiiiiiiiife.

Too bad, as I have this lovely mental image of some little wild child in dirty shift playing a thigh bone flute while dancing a jig as an army of skeletons marches in lockstep at their back.

I love the idea that a bard plays music so vile, he actually makes his enemies fight worse. All I can picture is a Skrillex bard.
