* The type of creature affected can be determined by die roll (see the specific item description for more information).
** The DM shouldn't reveal the exact nature of the potion.

Oil of Timelessness: When this oil is applied to any matter that was once alive (leather, leaves, paper, wood, dead flesh, etc.), it allows that substance to resist the passage of time. Each year of actual time affects the substance as if only a day had passed. The coated object has a +1 bonus on all saving throws. The oil never wears off, although it can be magically removed. One flask contains enough oil to coat eight man-sized objects, or an equivalent area.

Philter of Glibness: This potion enables the imbiber to speak fluently--even tell lies--smoothly, believably, and undetectably. Magical investigation (such as the 4th-level priest spell, detect lie) will not give the usual results, but will reveal that some minor "stretching of the truth'' might be occurring.

Philter of Love: This potion causes the individual drinking it to become charmed (see charm spells) with the first creature seen after consuming the draught. The imbiber may actually become enamored if the creature is of similar race and of the opposite sex. Charm effects wear off in 1d4+4 turns, but the enamoring effects last until a dispel magic spell is cast upon the individual.

Philter of Persuasiveness: When this potion is imbibed the individual becomes more charismatic, gaining a bonus of +5 on reaction dice rolls. The individual is also able to suggest (see the 3rd-level wizard spell, suggestion) once per turn to all creatures within 30 yards of him.

Philter of Stammering and Stuttering: When this liquid is consumed, it will seem to be beneficial--philter of glibness or persuasiveness, for instance. However, whenever a meaningful utterance must be spoken (the verbal component of a spell, the text of a scroll, negotiation with a monster, etc.), the potion's true effect is revealed--nothing can be said properly, and the reactions of all creatures hearing such nonsense will be at a -5 penalty.

Plant Control: A plant control potion enables the individual who consumes it to influence the behavior of vegetable life forms. This includes normal plants, fungi, and even molds and shambling mounds--within the parameters of their normal abilities. The imbiber can cause the vegetable forms to remain still or silent, move, entwine, etc., according to their limits.

Vegetable monsters with Intelligence of 5 or higher are entitled to a saving throw vs. spell. Plants within a 20-foot by 20-foot square can be controlled, subject to the limitations set forth above, for 5d4 rounds. Self-destructive control is not directly possible if the plants are intelligent (see charm plants spell). Control range is 90 yards.

Poison: A poison potion is simply a highly toxic liquid in a potion flask. Typically, poison potions are odorless and can be of any color. Ingestion, introduction of the poison through a break in the skin, or, in some cases, just skin contact, will cause death. Poison can be weak (+4 to +1 bonus to the saving throw), average, or deadly (-1 to -4 penalty or greater on the saving throw). Some poison can be so toxic that a neutralize poison spell will simply lower the toxicity level by 40%--say, from a -4 penalty to a +4 bonus to the saving throw vs. poison. The DM selects the strength of poison desired, although most are strength "J'' (see Table 51, Poison Strength). You might wish to allow characters to hurl poison flasks (see Combat, "Grenade-Like Missiles").

Polymorph Self: This potion duplicates the effects of the 4th-level wizard spell of the same name.

Rainbow Hues: This rather syrupy potion must be stored in a metallic container. The imbiber can become any hue or combination of hues desired at will. Any color or combination of colors is possible, if the user simply holds the thought in his mind long enough for the hue to be effected. If the potion is quaffed sparingly, a flask will yield up to seven draughts of one hour duration each.

Speed: A potion of speed increases the movement and combat capabilities of the imbiber by 100%. Thus, a movement rate of 9 becomes 18, and a character normally able to attack once per round attacks twice. This does not reduce spellcasting time, however. Use of a speed potion ages the individual by one year. The aging is permanent, but the other effects last for 5d4 rounds.

Super-Heroism: This potion gives the individual a temporary increase in levels (see heroism potion) if he has fewer than 13 levels of experience. It is similar to the heroism potion, but more powerful, and its effects last just 5d6 melee rounds:

Sweet Water: This liquid is not actually a potion to be drunk (though it tastes good). Sweet water is added to other liquids in order to change them to pure, drinkable water. It will neutralize poison and ruin magical potions (no saving throw). The contents of a single container will change up to 100,000 cubic feet of polluted, salt, or alkaline water to fresh water. It will turn up to 1,000 cubic feet of acid into pure water. The effects of the potion are permanent, but the liquid may be contaminated after an initial period of 5d4 rounds.

Treasure Findings: A potion of treasure finding empowers the drinker with a location sense, so that he can point to the direction of the nearest mass of treasure. The treasure must be within 240 yards, and its mass must equal metal of at least 10,000 copper pieces or 100 gems or any combination.

Note that only valuable metals (copper, silver, electrum, gold, platinum, etc.) and gems (and jewelry, of course) are located. The potion won't locate worthless metals or magical items which don't contain precious metals or gems. The imbiber of the potion can "feel'' the direction in which the treasure lies, but not its distance.

Intervening substances other than special magical wards or lead-lined walls will not withstand the powers that the liquor bestows upon the individual. The effects of the potion last for 5d4 rounds. (Clever players will attempt triangulation.)

Undead Control: This potion in effect gives the imbiber the ability to charm certain ghasts, ghosts, ghouls, shadows, skeletons, spectres, wights, wraiths, vampires, and zombies. The charm ability is similar to the 1st-level wizard spell, charm person. It affects a maximum of 16 Hit Dice of undead, rounding down any hit point additions to the lowest die (e.g., 4 + 1 equals 4 Hit Dice). The undead are entitled to saving throws vs. spell only if they have intelligence. Saving throws are rolled with -2 penalties due to the power of the potion; the effects wear off in 5d4 rounds. To determine the type of undead affected by a particular potion, roll 1d10 and consult the following table:

Ventriloquism: This allows the user to make his voice sound as if it (or someone's voice or a similar sound) were issuing from someplace other than where he is--from another creature, a statue, from behind a door, down a passage, etc. The user can speak in any language he knows, or make any sound he can normally make. To detect the ruse, listeners must roll a successful saving throw vs. spell with a penalty of -2. If cast in conjunction with other illusions, the DM may rule greater penalties or disallow an independent saving throw against this effect--the combined illusion may be perfect! The imbiber can use the ventriloquism ability up to six times within the duration of the potion.

Vitality: This potion restores the user to full vitality despite exertion, lack of sleep, and going without food and drink for up to seven days. It will nullify up to seven days of deprivation, and will continue in effect for the remainder of its seven-day duration. The potion also makes the user proof against poison and disease while it is in effect, and the user will recover lost hit points at the rate of 1 every 4 hours.

Water Breathing: It is 75% likely that a water breathing potion will contain two doses, 25% probable that there will be four in the container. The potion allows the character drinking it to breathe normally in liquids that contain suspended oxygen. This ability lasts for one full hour per dose of potion quaffed, with an additional 1d10 rounds (minutes) variable. Thus, a character who has consumed a water breathing potion could enter the depths of a river, lake, or even the ocean and not drown while the magical effects of the potion persisted.
