Good lord these things are nasty. Massive big old evil dragon clerics and are evil counterparts to the Sacred Warder of Bahamut. Their profane blast makes an unholy breath weapon not subject to energy resistance and wall of force and prismatic wall can't save your asses, cowards. The previously mention Sacred Warder of Bahamut is about the only thing that can stop these nasty and powerful dragons.

Class Features

All of the following are class features of the Unholy Ravager of Tiamat.

Weapon and Armor Proficiency: A Unholy Ravager of Tiamat is proficient with whatever they were already proficient with.

Divine Conversion: At 1st level, an unholy ravager loses any effective sorcerer level it had previously gained by virtue of its age and draconic variety. Its effective divine spellcasting level increases by the number of sorcerer levels it sacrificed, allowing the dragon to cast cleric spells much more effectively. These effective levels apply only to the dragon’s spellcasting, not to other class abilities (such as turning undead or wild shape) For example, a very old red dragon/1st-level cleric adopts the unholy ravager of Tiamat prestige class. Its sorcerer caster level of 13th converts into thirteen effective cleric levels in addition to its 1 level of cleric, giving the dragon the spellcasting ability of a 14th-level cleric.

Smite: An unholy ravager of Tiamat adds its class levels to its cleric levels to determine its bonus on damage when using its smite ability (the granted power of the Destruction domain). At 4th level, 8th level, and 12th level, an unholy ravager can use its smite ability one additional time per day.

Spellcasting: From 2nd level on, when a new unholy ravager level is gained, the dragon gains new spells per day as if it had also gained a level in a divine spellcasting class it belonged to before it added the prestige class. It does not, however, gain any other benefit a character of that class would have gained (an improved chance of turning or rebuking undead, wild shape, and so on). This essentially means that the dragon adds the level of unholy ravager to the level of whatever divine spellcasting class the dragon has, then determines spells per day and caster level accordingly. If the dragon had more than one divine spellcasting class before becoming an unholy ravager, the dragon must decide to which class it adds each level of unholy ravager for the purpose of determining spells per day. A very old red dragon/1st-level cleric/2nd-level unholy ravager has the spellcasting ability of a 15th-level cleric: 13 from divine conversion of its sorcerer spellcasting levels, 1 from its single cleric level, and 1 from its two levels in the prestige class. If a dragon advances an age category after taking levels in this class, the added levels of spellcasting ability are added to its effective divine spellcasting level. If the very old red dragon example above lives to be ancient, its spellcasting level would increase by 2, so it would cast spells as a 17th-level cleric.

Breath Weapon Substitution Sp: A 2nd-level unholy ravager of Tiamat can use breath weapon substitution at will. However, using this ability increases the number of rounds the dragon must wait before using its breath weapon again by 1 round, as if it were using a metabreath feat.

Aura of Despair Su: At 3rd level, an unholy ravager’s frightful presence alters slightly. In addition to the fear effect, creatures within the radius of the dragon’s frightful presence take a –2 penalty on all saving throws. This penalty is applied before creatures roll their saving throws against the frightful presence effect itself.

Profane Blast Su: At 7th level, an unholy ravager of Tiamat can unleash a narrow blast of raw profane energy from its mouth three times per day. The blast is a ray, requiring a ranged touch attack, with a range of 400 feet + 40 feet per class level. The blast looks and feels like energy of the same type as the dragon’s breath weapon. If it hits a target, it deals the same number of dice worth of damage as the dragon’s breath weapon, but uses d12s. (So, a great wyrm blue dragon would deal 24d12 points of damage with its profane blast.) The damage it deals results directly from divine power and is therefore not subject to being reduced by protection from energy and similar magic. Each use of this ability counts as a use of the dragon’s breath weapon, so it cannot use its breath weapon for 1d4 rounds after issuing a profane blast. An unholy ravager can target a creature behind a wall of force, prismatic wall, or prismatic sphere with its profane blast. The dragon makes a special dispel check, rolling 1d20 + its age category + its class level against a DC of 11 + the effect’s caster level. If this check is successful, the effect is instantly negated (all layers in a prismatic effect are destroyed) and the ray goes on to strike the intended target (if the ranged touch attack roll is successful). A profane blast is stopped normally by a sacred warder of Bahamut’s sacred shield.

Mass Profane Blast Su: At 12th level, an unholy ravager of Tiamat’s profane blast occupies the same area as its breath weapon and affects all creatures within that area. The dragon can choose whether to use a ray profane blast or a mass profane blast, and can use both abilities no more than a total of three times per day. If a wall of force or prismatic effect is within the area of a mass profane blast, the dragon makes a special dispel check as described above for each such effect within the area.
