Custom Poisons

Written by Lester Gash.

Adventurers, particularly those of a more amoral or mercenary bent, often make use of poisons. Poisons are usually ingested, but some very vile concoctions can kill merely through contact with the flesh and others might be a dust or gas. 
 
Rather than being bought by tier, like other potions, poisons are purchased with different effects in mind. Each effect you wish your poison to have increases its cost and if a incredibly deadly poison is desired the DM may determine that it may take some time to concoct, or that specialist, hard to come by, ingredients may be required. Whilst there is no limit to the number of effects you can combine into one poison this is, again, likely to substationally increase the time the poison requires to make and the rarity of ingredients.
 
When constructing your potion you will need at least one method of affliction (ingested, inhaled, or through skin contact) and one effect. 
 
In the vast, vast, majority of cases the victim will not willingly take the poison. In this situation you must attempt to conceal your vile concoction in such a way that it will afflict them. Common places are in a meal, or drink. The base difficulty for this is a hard environment appropriate roll. Making the potion more difficult to detect, such as making it tasteless, can decrease the difficulty of this check. The consequences of being spotted will depend entirely on how you're attempting to conceal your poison! It's possible you may get another chance. Of course, it's entirely possible it won't be spotted until after you've left the scene. 
 
As a final note, I encourage you to come up with exotic and interesting names for your poisonous creations! The deadlier the effect, the fouler name it deserves! 
 
Effects: 
 
Blindness - Victims of this poison will be robbed of their eyesight (in combat they are weakened and vulnerable). Saving against this effect is  hard (16+), and the interval taken depends on the amount spent on the effect.

Colourless - Cost: 500gp - The poison is colourless and will add no tint to any other liquids it may be placed within. It decreases the difficulty of the conceal check by 3. 
 
Deafness - This poison robs the afflicted of their hearing (in combat they are dazed). Saving against this effect is  hard (16+), and the interval taken depends on the amount spent on the effect.

Delayed Effect - Cost: 50gp an hour - It can often be advantageous to have a poisons effect, or effects, occur at a later time. It is even possible to stagger effects, having a victim first suffer one indignity, then another, before finally succumbing. The base cost is for a poison as a whole. Each individual delayed effect must be paid for separately. (so for a poison that causes blindness immediately, then delusions an hour later, and death two hours after that, the cost would be as follows: 50gp for delaying delusions for an hour, and 100gp to delay the lethality effect, for a total of 150gp extra gold pieces)
 
Delusions - Whatever is in this poison causes terrible hallucinations and delusions in the victim (in combat they are confused) and will cause them to act unpredictably. Saving against this effect is  hard (16+), and the interval taken depends on the amount spent on the effect.

Exotic - Cost: 2000gp - Rare, unusual, ingredients such as basilisk tears or gelatinous cube jelly make this poison incredibly expensive, but much harder to detect and identify. Conceal attempts with this poison are decreased by 8. The expense of obtaining such ingredients may be prohibitively expensive, but perhaps enterprising adventurers may be able to find them on their travels. 
 
Ingested - Cost: 210gp - This poison will afflict its victim upon being ingested. It will usually be foul tasting, however.      
 
Inhaled - Cost: 1050gp- Either as a gas, or dust, this poison can be inhaled. If in a glass or ceramic bottle it can be thrown as a weapon, afflicting d6 nearby creatures. 
 
Lethal -  Utterly deadly, this poison can kill instantly. Even if you were to survive, you may wish you hadn't. If the victim has less than the threshold hit points, they die instantly. If they have above this amount, roll the dice to determine damage - there's still a strong chance they'll die, but even survival will leave them significantly weakened. 
 
Cost Deady To (HP or less) Damage Dealt if above HP threshold (average)
1050gp 54 1d100
2125gp 108 2d100
4250gp 216 3d100
 
Odourless - Cost: 500gp - This poison has no detectable scent, making it harder to detect before it's too late. The difficulty of the conceal check is lowered by 3.
 
Paralysis - Cost: - Seizing and numbing limbs, this poison is incredibly debilitating. (in combat, the victim is stuck)  Saving against this effect is  hard (16+), and the interval taken depends on the amount spent on the effect.

Permanency - Cost: 1000gp - Making an effect permanent is a little more expensive, but often worthwhile. Purchasing this effect on top of the cost of the longest duration for the effect you wish to make permanent guarantees the victim a torrid time. 
 
Petrification - Cost: 3250gp - Turning flesh to stone is a terrible effect, but is at least reversible through ritual magic. Some of the time. As a bonus you get a realistic statue and if you're really lucky it won't be contorted in a death grimace. This poison will petrify a target with less than 216hp. Vigorous exertion can see off this effect; thus, if used in combat the victim must fail four hard saves before finally succumbing. 
 
Sickness - Cost: 500gp - Vomiting and diarrhoea are the unpleasant symptoms of this poison. Debilitating, in their own way.
 
Skin Contact - Cost: 850gp - Some rare poisons can afflict even upon skin contact. Careful handling required. 
 
Species Specificity - Cost: 1050gp - Only a foolish king has a food taster from a different race. Poisons with this effect only affect the species designated at purchase.
 
Tasteless - 300gp - With no detectable taste, this poison can be safely sprinkled over a meal or a glass of wine. The difficulty of the conceal check is lowered by 3.
 
Unconsciousness - - Causing a deep slumber, or perhaps a total blackout, this poison is a non-lethal alternative, particularly when combined with permanency. Saving against this effect is  hard (16+), and the interval taken depends on the amount spent on the effect. It may also be possible that the victim can be woken by other specific means - like a good, hard, thump or the kiss of a beautiful prince(ss). Entirely up to you.
