A corroder, as the name implies, is a spellcaster who specializes in corrosive liquids. Nothing pleases a corroder quite like watching a carefully brewed acid at work, and no music is sweeter to them than the gentle hiss of a corrosive liquid as it eats its way through wood, metal, flesh, or bone.The first known corroder, Flibixia the scathing, was said to have lived during the Sixth Age of Migdalia. Believing that the endless contraptions and clockworks that her fellow gnomes continually tinkered with were nothing but trouble, Flibixia instead chose to focus on alchemy, eventually becoming one of the most renowned alchemist in Migdalian history.
Though Flibixia was an exceptional alchemist and a brilliant wizard, she was a terrible teacher. Her merciless critiques of her students’ every fault, as well as her legendary temper, soon drove away every apprentice she accepted. Many of these gnomes were so traumatized by her scathing insults that they gave up wizardry altogether, and more than a few were known to fall into trembling fetal positions at the mere mention of her name. Only a single apprentice seemed impervious to her verbal assaults, a goblin woman known as Droomix.
Droomix arrived in Poggle with a large round bundle, inquiring as to whether the gnome alchemist in town was accepting apprentices. Ignoring the constant warning and angry glares he received from the gnomes, the young goblin eventually found Flibixia’s large home. Knocking on the door, she was soon greeted by a frantic-looking gnome, her hair uncombed and wild. Flibixia, surprised at seeing a goblin sullying her doorstep, launched herself into a tirade, heaping insult upon insult onto the hapless goblin.
Droomix’s grasp of the gnomish tongue was poor, however, and with Flibixia talking so fast, the goblin could not understand what the frantic gnome was screaming at her. Shrugging, the goblin assumed that the gnome was asking what she was holding, and thrust the round bundle into Flibixia’s face. The gnome’s voice trailed off as her gaze fell upon what the goblin was holding: a faint grey egg, nearly half the size of either woman, covered with small black spots. Amazed, Flibixia pulled the goblin into her home, asking so many questions in such short order that the goblin could do little but stare at the gnome in confusion. Thus began Droomix’s apprenticeship.
As the months passed, the Flibixia and Droomix studied the strange egg. The egg, they found, possessed near total resistance to acids of all kinds, as well as a shell as hard as steel. When the egg hatched early in the spring, revealing a very confused and very angry black dragon wyrmling, things began falling into place for the two alchemists. After finally chasing the creature from her house with an old broom, Flibixia spent the day repairing the damage dealt by the rampaging creature. The next morning, however, Droomix, was nowhere to be found, and Flibixia assumed, with not a little sadness, that her apprentice had fled for good. That fall, however, Droomix reappeared on Flibixia’s doorstep, horribly scarred and wounded, dragging her mangled right leg behind her. The only thing the goblin carried with her were a number of reeking, filthy scrolls, seemingly inked onto rotting flesh.
The scrolls, Droomix told the gnome, belonged to the priest of Kalosh who controlled her tribe. Droomix had sneaked into the old goblin’s quarters and stolen the scrolls, only to be surprised by the priest as he returned just as Droomix was leaving. A fierce battle had erupted, and, though Droomix was able to defeat the goblin and escape, she was gravely injured during the fight. When Flibixia asked what was on the scrolls that was so important, Droomix simply grinned and handed the filthy skins to the gnome. Holding her nose in an attempt to block out the smell, Flibixia unrolled the scrolls and began to read the rotting scrolls. What she found shocked her.
The writings, obviously a translation from another source, spoke of an ancient Kaloshian ritual which removed the soul of one creature and bound it to another, strengthening the recipient. Flibixia immediately grasped what Droomix had intended...if they could bind the soul of a dragon to their own, then they may be able to gain some, or all, of the dragon’s resistance to acid, enabling them to manipulate corrosive substances in ways no mortal had ever dreamed of.
Flibixia used her connections among the Clockwork Consortium to arrange for every discovered dragon egg to be returned to her in Poggle, while she and Droomix began studying the scrolls to remove all traces of Kalosh’s malign power from the rituals mentioned therein. They finished purifying the ritual only a few days before the first of what would be many dragon eggs was delivered by Consortium warforged. Flibixia was the first to attempt the ritual, which worked better than either had suspected. Droomix attempted the ritual the night the second egg arrived, achieving the same mastery over acid which Flibixia now possessed. Ecstatic, they made multiple copies of the ritual, along with their finding, which they published in a tome named the Codex of Corrosion. Though both Flibixia and Droomix were later eaten by a massive black dragon seeking revenge for its children, the Codex has survived to the current day, tempting alchemists with the promise of complete mastery over acid.
Hit Dice: d4
Requirements
In order to qualify to become a Corroder, a character must meet the following criteria.
Skills: Craft (alchemy) 8 ranks, Spellcraft 8 ranksFeats: Energy Substitution (acid), Great Fortitude
Spellcasting: Ability to cast Melf's acid arrow
Special: Must perform the ritual described in the Codex of Corrosion. The ritual requires an unhatched black dragon egg, and requires 10 rounds from start to finish. Once begun, nothing can halt the ritual’s progress. Each round, the character takes 1d4 points of acid damage as his soul is fused with that of the unhatched wyrmling. Should this damage be healed or prevented in any way, the ritual fails and the egg is ruined. With the completion of the ritual, the character gains his first level of corroder.
Class Skills
The Corroder’s class skills (and the key ability for each skill) are Concentration (Con), Craft (Int), Intimidate (Cha), Knowledge (arcana) (Int), Listen (Wis), Profession (Wis), and Spellcraft (Int). See Chapter 4 of the Player’s Handbook for skill descriptions.

Class Features:
All of the following are class features of the Corroder prestige class.
Weapon and Armor Proficiency: A corroder gains no new weapon or armor proficiency.
Spellcasting: A corroder continues training with magic. Thus, at every even-numbered corroder level, the character gains new spells per day and spells known as if he had also gained a level in whatever arcane spellcasting class he belonged to prior to adding this prestige class. He does not, however, gain any other benefit a character of that level would have gained (improved familiar abilities, metamagic or item creation feats, etc).
Bonded Soul (Su): The process of binding a black wyrmling’s soul to his own grants a corroder complete immunity to all forms of acid. This immunity does not extend to equipment or clothing worn by the corroder. As a side effect from the bonding ritual, however, the corroder now detects as a dragon to all forms of magical detection, and spells able to affect dragons now affect him as if he were a dragon.
Vial Throw (Su): A corroder is skilled at throwing vials of acid at his opponents. The range increment of any vial thrown by the corroder increases by 10 feet.
Corrosive Spells (Su): At 2nd level, the corroder learns how to infuse his spells with acidic energy, not only dealing acid damage to his enemies, but infecting their wounds as well. Spells he casts deal an additional +1d4 points of acid damage for every three corroder levels he possesses, to a maximum of +3d4 acid damage at 9th level. This additional acid damage continues to damage creatures in future rounds, dealing 1d4 less acid damage with each successive round. The corroder chooses whether to use this ability as he begins casting the spell in question. Note that this ability may only be used in conjunction with cast spells; manifested powers and supernatural or spell-like abilities are unaffected.
Acid Arcana (Su): At 3rd level, the corroder’s mastery over acid increases, and spells he casts that deal acid damage become more difficult to resist. The saving throw DC of any spell the corroder casts with the “Acid” descriptor increases by +1.
Blinding Fumes (Su): Beginning at 3rd level, the corroder is continually surrounded by noxious fumes which burn and irritate his opponents’ eyes. This ability is essentially a blur spell, though it only affects the attack rolls of creatures within five feet of him (thus, creatures wielding reach weapons are unaffected by this ability). Creatures immune to acid may ignore the effects of this ability.
Acid Arrow Barrage (Su): At 4th level, the corroder’s mastery of acid manifests itself as an innate ability to hurl magical acid at his opponents. This ability is similar to a Melf’s acid arrow spell, except that four arrows are created instead of one. Each of these arrows can be hurled at an the same or different creatures (as a single standard action, though the corroder makes a separate attack roll for each arrow), though all creatures targeted in this way must be within 15 feet of each other. Each arrow continues to deal damage in successive rounds. This ability is usable once per day, and is cast as if by a sorcerer of the corroder’s class level.
Corrosive Grasp (Su): Beginning at 5th level, the corroder is able to secrete acid from his body. His unarmed or natural weapons deal an additional 1d6 points of acid damage, and he is treated as if he is no longer treated as if he were unarmed when fighting without a weapon. In addition, any creature or object touching him takes this same amount of damage each round he uses this ability. The corroder may activate or deactivate this ability as a free action on his turn.At 9th level, the corroder’s corrosive grasp ability increases to 2d6 points of acid damage.
Vitriolic Burst (Su): At 6th level, the corroder’s mastery over acidic magic improves, allowing him to infuse his spells with the “Acid” descriptor with additional corrosive energies. Every such single- or multiple-target spell cast by the corroder deals additional splash damage to every creature within five feet of one of spell’s targets. Spells that affect an area, rather than a target, instead deal this splash damage to all creatures in the five feet surrounding the spell’s area of effect. This additional damage is equal to the corroder’s class level.
Corrosive Blood (Su): Upon reaching 7th level, the corroder’s blood changes to becomes highly corrosive, damaging those who come in contact with it. Any time a slashing or piercing weapon deals damage to the corroder, his blood splashes out, dealing 1d6 points of acid damage to everything within 5 feet of him. This damage applies to any armor or clothing worn by the corroder or her opponent, as well as anything held by either character. The weapon which struck her takes an additional 1d6 points of acid damage.Alternatively, the corroder may cut himself and bottle his own acidic blood. By dealing one point of Constitution damage to himself, the corroder is able to fill one vial as a full-round action. Such blood remains potent for one day, and deals 2d6 points of acid damage on a direct hit, and 2 points of splash damage to everything within 5 feet.
Acidic Breath (Su): By exhaling a thick, caustic cloud of corrosive vapors, an 8th level corroder is able to produce an acidic fog effect three times per day. This ability functions as if cast by a 15th level sorcerer, but with a range of Close.
Dissolve (Su): Upon reaching 10th level, the corroder’s body has completely adapted to the acid infusing it, granting him a powerful attack. He gains the ability to vomit forth a deluge of incredibly concentrated stomach acid, dissolving anything (and anyone) that comes in contact with the acid. This ability is similar to a disintegrate spell, save that it is effective only within a range of 10 feet, affects everything worn or held by a targeted creature, and deals acid damage (thus, a creature immune to acid would be immune to the effect, but its equipment may not be). This ability is usable once per day, and has a save DC of 10 + the corroder’s class level + his Con modifier.
