This is a focused, impressed spell, affecting a liter
of specially prepared water. The water contains a very small amount of herb
tea. When a character drinks the water, the spell works as a countering agent
to any poisons present in the body. If the spell's effect value is greater than
the strength of the poison, then the poison has no effect at all.
Unfortunately, the reverse is also true.
The antidote remains in the target's system for the
entire duration and attempts to counter any new poisons that enter the body.
The spell remains at full potency unless defeated, in which case its protection
is destroyed. The poisons it has already overcome will stay inert, but any
subsequent poisons will take full effect.
