This lean quick-looking bipedal frog-like creature appears enduring and powerful. Its skin is bright platinum and looks smooth. Its majestic mane of golden hair flows down its back. It is adorned in regal full plate with no helm.
Only those well-trained in the ways of the planes are aware of the existence of a small but growing order of slaadi that have completely forsaken the evil ways of their chaotic brethren. Created by an ancient life slaad, the order has grown a hundredfold in the centuries since he left Limbo for the Heroic Domains of Ysgard. After a time, he came to the Olympian Glades of Arborea where he befriended a powerful Eladrin who taught him what it truly means to be Chaotic Good.
Holy slaadi are created when a life slaad that has reached 20 Hit Dice views Morwel, Queen of Stars, for the first time. If the life slaad chooses, it can swear an oath to uphold what it means to be Chaotic Good. It loses its Gaze of Wrath, its heart tranquil after viewing the Queen. In return, the life slaad becomes a powerful champion for the forces of Good.
Holy slaadi are as arrogant as any of their kind, but are also benevolent and kind. They uphold a paladin-like ethos. They journey to other planes to champion the cause of Good and defend the weak from tyrants. Holy slaadi speak Abyssal, Celestial, Common, Draconic, Infernal, and Slaad.
Combat
Holy slaadi only embrace combat against evil or lawful opponents. Otherwise, they are as calm and reserved as a slaad can be.
Aura of Courage (Su): A holy slaad is immune to fear (magical or otherwise). Each slaad within 10 feet of it gains a +4 morale bonus on saving throws against fear effects. This ability functions while the holy slaad is conscious, but not if it is unconscious or dead.
Break Enchantment (Sp): A holy slaad can produce a break enchantment effect, as the spell, five times per week.
Change Shape (Su): A holy slaad can assume any humanoid form as a standard action. In humanoid form, a holy slaad cannot use its natural weapons. A holy slaad remains in one form until it chooses to assume a new one. A change in form cannot be dispelled, but a holy slaad reverts to its natural form when killed. A true seeing spell reveals its natural form.
Divine Grace (Su): A holy slaad gains a bonus equal to its Charisma bonus on all saving throws.
Divine Guard (Su): A holy slaad gains its Charisma bonus as an insight bonus to its Armor Class.
Divine Health (Ex): A holy slaad is immunity to all diseases, including supernatural and magical diseases.
Lay on Hands (Su): A holy slaad can heal wounds (its own or those of others) by touch. Each day it can heal a total number of hit points of damage equal to its Hit Dice x its Charisma bonus. A holy slaad may choose to divide its healing among multiple recipients, and it doesn’t have to use it all at once. Using lay on hands is a standard action.
Alternatively, a holy slaad can use any or all of this healing power to deal damage to undead creatures. Using lay on hands in this way requires a successful melee touch attack and doesn’t provoke an attack of opportunity. The holy slaad decides how many of its daily allotment of points to use as damage after successfully touching an undead creature.
Paladin Abilities: A holy slaad’s Hit Dice stack with its paladin levels for determining its caster level for spells and spell-like abilities, lay on hands, remove disease, smite evil, and turn undead abilities.
Smite Law (Su): A holy slaad adds its Charisma bonus to its attack roll and deals 1 extra point of damage per Hit Dice.
Spell-like Abilities: At will-animate objects, chaos hammer (DC 20), cure critical wounds, detect law, detect magic, dispel law (DC 22), fly, greater invisibility, halt undead (DC 19), heal mount, identify, magic circle against law, neutralize poison, prayer, remove disease, see invisibility, shatter (DC 18); 3/day-cloak of chaos (DC 24), undeath to death (DC 22), word of chaos (DC 23); 1/day-blade barrier, heal, whirlwind. Caster level 20th. The save DCs are Charisma-based.
Spells: A holy slaad casts spells as an 18th level paladin.
Typical Paladin Spells Memorized (4/3/3/2; DC 14 + level; Caster Level 9th): 1-bless weapon, divine favor, lesser restoration, read magic. 2-bull’s strength, owl’s wisdom, resist energy. 3-daylight, dispel magic, greater magic weapon. 4-holy sword, restoration.
Summon Slaad (Sp): Twice per day, a holy slaad may automatically summon 1-2 life slaad. Alternately, a holy slaad can summon a ghaele eladrin with a 60% chance of success. This is the equivalent of a 9th level spell.
Turn Undead (Su): A holy slaad has the supernatural ability to turn undead. It may use this ability a number of times per day equal to 3 + its Charisma modifier. It turns undead as a cleric of three levels lower than its Hit Dice would. A holy slaad receive a +2 synergy bonus on checks to turn undead.
Feats: Divine Might and Extra Smiting are from Complete Warrior. Knight of Stars is from Book of Exalted Deeds.
Possessions: +4 full plate.
