Yeenoghu is a ferocious melee combatant who fights with a reckless abandon that most demons attribute to his once being mortal, as true demons are aware of their weaknesses and far more self-preserving than he. Yeenoghu also adds his total Strength score (not his Strength modifier) to attack and damage rolls. His tremendous effectiveness in melee is enhanced both by his hyena-like traits (which allow him to attack more effectively as part of a group) and his demonic traits, the powers of which cause him to move swiftly across the battlefield. While his spell-like abilities may be less numerous or powerful than those of other demon lords, they serve their purpose in allowing him to utilize his melee abilities to the fullest extent possible.

Lastly, Yeenoghu can burn off some of his essence to stop magic dead in its tracks. As a free action that can be used outside of his turn, Yeenoghu can lose 44 hit points to counter any spell, supernatural ability , or spell-like ability in Medium range, as if by [[SRD:Greater Dispel Magic|''greater dispel magic'']] (although it can counter supernatural and spell-like abilities as if they were spells). This ignores temporary hit points, and can be used any number of times. For any ability with an ongoing or permanent duration, this merely suppresses it for 6 rounds.

'''{{Anchor|Lord of the Abyss}} ([[Su]]):''' His own personal power, and the spoils of his victories over others, have made Yeenoghu a terror of the Abyssal realm. He receives a +8 enhancement bonus to attack rolls and damage rolls, a +8 resistance bonus to all saves , and a +6 deflection bonus to AC. Yeenoghu also has maximum hit points per hit die.

Additionally, the Abyss itself protects Yeenoghu from any attempt to scry on him. Anyone that uses a divination effect on Yeenoghu or the area within 1 mile of him must make a DC 32 Will save or become dazed for 1 round, and ending the effect automatically. Additionally, if the save is failed and Yeenoghu wishes it, he can use an immediate action to transport himself over to the location of the user of the divination effect, even if it is on a different plane.

'''{{Anchor|Pack Attack}} ([[Ex]]):''' As an free action useable out of turn, Yeenoghu can make a single melee attack against an opponent that has just been struck by one of his allies in melee , so long as he also threatens the target in melee. Furthermore, Yeenoghu is able to use ''[[Summon Monster (3.5e Spell)|summon monster]]'' as an at-will spell-like ability.

'''{{Anchor|Ravage Form}} ([[Sp]]):''' As a full-round action, Yeenoghu may bestow his ravage on a creature eligible to gain a level. That creature gains its first level in the [[Ravaged by By Yeenoghu (3.5e Racial Paragon Class)|Ravaged by Yeenoghu]] racial paragon class. If Yeenoghu attempts to ravage an unwilling creature, it receives a DC 32 Will save to resist (Cha-based).

If Yeenoghu wishes, he can attempt to share the senses of a creature that has at least one level in ravaged by Yeenoghu. This works identically to a [[SRD:Scrying|''scrying'']] spell, except it must be centred centered on the creature in question. The creature doesn't get any say in the matter. Abaddon Yeenoghu may use this ability at will. This has a caster level of 22nd.

Caster level 22nd, DCs are Charisma-based (default 32).

The enhancement bonus of the flail is overridden by that of Yeenoghu's [[#Lord of the Abyss|lord of the Abyss]] ability. The chains on the flail automatically extend and contract as appropriate, giving the wielder double their normal reach when using it. Each time Yeenoghu makes a successful melee attack roll, roll 1d6 to determine how which heads strike successfully (see based on the [[#Table: Flail of the Conqueror|table]] below).Each head deals an identical amount of base damage (10d12) and can deal piercing, slashing, or bludgeoning damage at Yeenohgu’s whim. They also each have a unique effect as described below. All save DC’s from the heads are Strength-based and have a save DC of 35.

*''The Balor‘s Head:'' Though Yeenoghu has fought and destroyed countless demons, few possessed sufficient power to be worth adding to his flail. This was not the case for the balor who previously claimed lordship over what is now Yeenoghu’s layer, marking his final significant test on his way to becoming a demon prince. Upon striking an opponent, it The Balor's Head releases a blast of elemental energy that deals the same an amount of damage that the head dealt with that hitequal to The Balor's Head's base damage. This extra damage can either be acid, cold, electricity, or fire damage (chosen by Yeenoghu at the moment the damage is dealt), but regardless of the type a successful Reflex save halves the bonus damage dealt.

In the Abyss, Yeenoghu maintains good relations with the [[Molydeus (3.5e Monster)|molydei]], but has attracted the ire of [[Baphomet (3.5e Monster)|Baphomet]] due to what has been perceived as an attempt to steal followers. He also surrounds himself with fiendish gnolls and upon whom he commonly bestows his ravage, who serve as his new force in battle and frequent the vast expanse of his realm, which has become a hive of activity with the introduction of several gnoll armies into its borders, one of the key pieces in his bid to acquire more territory.
