Caustic Casting

            Hello, and welcome to a particularly acerbic Obscure Arcana. Not too long ago, I wrote an article giving lithomancers a little love. This week, I want to continue that trend with some spells for those who dedicate themselves to acid.

 

Acid Rain

Acid Rain

            This spell causes the skies in the affected area to fill with menacing, sickly-looking storm clouds which immediately begin to pour forth caustic, acid rain. For the spell’s duration, the area is affected as though by rain and severe wind (see the Pathfinder Roleplaying Game Core Rulebook for more information).

            Further, each creature and object within the area suffers 2d6 points of acid damage per round from the caustic rain. There is no saving throw to reduce or negate the damage, but any character who can protect himself from the rain (such as by finding shelter) does not suffer the damage (although whatever is sheltering them will be taking damage, and may be destroyed by the acid rain, leaving the character vulnerable again). The acid deals full damage (before hardness) to any and all objects in the area each round. Objects that gain the broken condition are no longer able to offer cover or protect creatures and objects from the rain.

            This spell can be cast inside or underground, but will always cause rain to fall from natural clouds above, meaning that if it is cast in such locations, you will not be able to see the effects unless the acid rain destroys the roof separating you from the sky.

 

Caustic Prison

Caustic Prison

            With this spell, you surround the target in a magical bubble of acid, which entraps him even as it melts away his body. This functions similarly to a resilient sphere, except as noted here. First, it has a hardness of only 10, and 5 hit points per caster level. Second, it is filled with acid, which deals 1d6 points of acid damage per 3 caster levels you possess to the target each round that he remains in the sphere.

            The target can attack the sphere from the inside to attempt to break it, and those outside the sphere can attack it from the outside as well. The target can also leave the sphere by magical means, such as dimension door. If the sphere is reduced to less than ½ its maximum hit points, it is pierced and the acid leaks out harmlessly, leaving the target imprisoned but ending the acid damage occurring each round. If the sphere is reduced to 0 hit points, it is destroyed and the target is freed. The sphere is immune to acid damage of all kinds.

            If you cease concentrating on the spell, its effects end, the sphere and its acidic contents dissipating harmlessly.

 

Illimar’s Greater Corrosion

Illimar's Greater Corrosion

            As with Illimar’s lesser corrosion, this spell causes caustic acid to spray forth from your fingertips. You must make a touch attack with the acid in order to hit the target. If you are adjacent to the target, or otherwise able to touch him, you can do so with a melee touch attack. Otherwise, you must make a ranged touch attack. If the target is outside of long range (400 ft. + 40 ft./ level), you cannot make an attack at all, and the spell is wasted.

            If the touch attack hits, the amount of damage it deals depends on how the attack was made. If it was a melee touch attack, it deals 1d6 points of acid damage per caster level (maximum 20d6 at 20th level). If it was a ranged touch attack, it deals 1d10 points of acid damage per two caster levels (maximum 10d10 at 20th level). If the target was farther away than a short range (25 ft. + 5 ft./2 levels) would allow, then the damage roll suffers a -1 penalty per die, and if the target was farther away than a medium range (100 ft. + 10 ft./level), there is an additional -2 penalty per die, for a total penalty of -3 per die (for example, if a 15th-level caster cast this spell on an adjacent target and hit him with a melee touch attack, it would deal 15d6 points of damage. If he cast it on a target 100 feet away, which is more than close range but within medium range, it would deal 7d10-7 points of damage. If he cast it at a target who was 300 feet away, which is more than medium range but within long range, it would deal 7d10-21 points of damage).

 

Illimar’s Insidious Bile

Illimar's Insidious Bile

            With this spell you spray forth a cone of stinking, acidic bile from between your outstretched hands. All creatures in the affected area take 1d8 points of acid damage per two caster levels (to a maximum of 10d8 points of acid damage at 20th level). A successful Reflex save halves this damage.

            Additionally, the conjured bile creates a cloud of noxious fumes in the same area. All creatures that enter or begin their turn within the affected area must succeed on a Fortitude save or be sickened for as long as they remain within the cloud, plus 1d6 rounds thereafter. These fumes persist for 1 round/level before dissipating.

 

Illimar’s Lesser Corrosion

Illimar's Lesser Corrosion

            This spell causes acid to spray forth from your outstretched fingers, damaging your foe. You must make a touch attack with the acid in order to hit the target. If you are adjacent to the target, or otherwise able to touch him, you can do so with a melee touch attack. Otherwise, you must make a ranged touch attack. If the target is outside of close range (25 ft. + 5 ft./2 levels) you cannot make an attack at all, and the spell is wasted.

            If the touch attack hits, the amount of damage it deals depends on how the attack was made. If it was a melee touch attack, it deals 1d6 points of acid damage per caster level (maximum 5d6 at 5th level). If it was a ranged touch attack, it deals 1d6 points of acid damage per two caster levels (maximum 5d6 at 10th level).
