Because of the need to recognize the auras of animals, low magic is a prerequisite for this skill. Once you master a poison, you will be able to discern what creatures produce the poison. You will need to kill the creature in order to extract poison from it. Note that the more skilled you are in poisons, the more poison you will be able to extract.

Extracting

Syntax:
EXTRACT <creature> INTO <vial>

You may extract known poisons of venomous creatures into vials. The amount you will be able to extract will increase as your skill in poisons increases.

Identification

When you probe a creature, you will be able to discern if it is venomous and what poison it produces. You will only be able to identify creatures with poisons known to you.

Additional Notes:
These poisons will cause these afflictions. Note that only unlinked astral creatures produce poison, though linked ones still give the same afflictions.

Miniatures

Syntax:
DIP <figurine> IN <crotamine>

You can dip miniatures in a vial of crotamine, making the figurine occasionally breathe a powerful corrosive cloud. The figurine will absorb the equivalent of 50 doses.
NOTE: Figurines coated in crotamine cannot also be coated in quicksilver nor can it wear knuckles/helmet.

Constructs

Syntax:
PREPARE CROTAMINE JELLY FROM <vial of crotamine>

Crotamine jelly can be put into a construct or colossus to enable the operator to attack his or her targets with a poison attack that does up to twice the damage to the target, at a cost of half damage to his or her own construct or colossus.

Immunity

Syntax:
IMMUNIZE

By taking a dose of poison, you will be able to train your body to become majorly resistant to poison. This is not an instantaneous process. Once your body is prepared to IMMUNIZE itself, you must take a sip of the poison you wish to be immune to. Then, at the beginning of the next month, you will find yourself greatly immune from its effects. Note that this only works against poisons, not against other spells that may give the same effect.
