This spell helps protect a
creature against attacks by all molds, slimes, puddings,
oozes, and other formless, primordial beings. All attacks
against the protected creature are made with a -2 penalty
and the protected creature’s saving throw has a +2 bonus.
In addition, the creature’s flesh is highly resistant to any
corrosive attack by such monsters, and is treated as being
solid stone for the purpose of withstanding a slime monster’s
corrosive attack. The spell negates up to 10d4 points
of damage from slime before it collapses.

MC: A bit of food mold pressed between 2 flat
stones, and a pinch of diamond dust.
