This spell conjures a corrosive, acidic slime of horrid strength on one
surface or creature within the spell’s range. Up to one square foot of surface area
per caster level can be affected, so a 5th-level caster can affect 5 square
feet—enough to create a 2-foot by 3-foot hole in a door or wall, or thoroughly
drench a man-sized creature. The acid eats through 6 inches of wood, leather, or
bone, 4 inches of stone, or 1 inch of metal each round. Against monsters composed
of stone, metal, or wood, the solvent inflicts 1d3 points of damage per caster
level per square foot affected in the first round, 1d2 per caster level in the
second round, and 1 per two caster levels in the third and final round.
Therefore, a 10th-level wizard who strikes a treant with solvent of corrosion inflicts 10d3, then 10d2, and finally 5 points of damage. Each round, the
victim is allowed a saving throw vs. spell for half damage.
Against flesh, the solvent is much less effective; it is caustic and burns
painfully, inflicting 1 point of damage per caster level in the first round, but
no further damage in the second or third round. However, the burning in the
following rounds does inflict a –2 penalty to the victim’s attacks while the
solvent is active. The solvent is extremely likely to cause extensive damage to the
victim’s armor and equipment; item saving throws vs. acid may apply at the DM’s
discretion. If the armor or equipment is magical in nature, then the saving
throw is made with the usual bonuses allowed to the magical item.
The great alchemist Vandarien developed his solvent to dissolve iron grates,
stone and woodwork traps, and other such hazards. The solvent’s effectiveness
against mineral or wood-based creatures was a mere side effect of his research.
The material component of this spell is a mixture of vinegar, water, and a drop
of black dragon acid.
