Throwing “attack” potions (sleep, paralysis, blindness, etc) should either always hit the target, or hit the floor at the target’s feet (causing vapor effects) if it fails the to-hit roll.

Strangulation protects you from drowning, since you cannot inhale water if you can’t inhale at all. It also prevents potion vapor inhalation effects and the inhalation effects of gas clouds. Basically it works like magical breathing except you die in 6 turns.

Allow sinks to be catalysts for alchemizing things. (Or possibly add a “cauldron” as a new piece of dungeon furniture, but that’s iffier.)

• You can dip potions into sinks to pour them down the drain, experiencing the vapor effects in a safe way. (Pouring polymorph down the sink of course polymorphs the sink.) This requires vapor effects to be implemented for many of the potions that don’t currently have any.
• If you don’t pour the potion down the drain, you instead mix it with the fluid from the tap, which is usually water but can already be a random potion.
• Possibly, doing alchemy in/on a sink is more efficient. There are many possible forms this could take, such as:
  • Potions not diluting when you mix them.
  • Reduced or zero chance of an alchemic blast.
  • You can get results from mixing potions that you can’t otherwise. (Flavor for this is weak. Is the character heating them somehow with the hot water?)

Inhaling vapors from a potion of gain level produces a message like “You smell hard work” or “You smell elbow grease” (perhaps if hallucinating), granting you 10% of the experience points needed to advance to the next level. Monsters may be similarly affected.

Note that the 10% is calculated just based on the level thresholds and your own experience points don’t matter (only your current level). If you are level 5, with level 5 reached at 120 points and level 6 reached at 200 points, you will always get 10% of (200-120) = 8 points.

Remove restore ability vapors healing monsters to max HP, because that makes no sense.

There should be three ways to interact with potions: drinking them, getting them spilled on the exterior of your body (e.g. having them thrown at you and hit you), and inhaling their vapors. These should all be fully symmetric between the player and monsters and have noticeable effects for most if not all potions.

You can dip a potion into a sink to pour water into it from the tap, diluting it and causing runoff which subjects you to vapor effects (hopefully identifying it). For simplicity, the 1/30 chance of a random potion coming out of the sink should probably be ignored here.

Alchemic golem, which is basically made out of potions. Its melee attacks expose you to random potion or potion vapor effects. Killing it drops a few random potions and causes more random vapor effects. It can spontaneously explode when it hits something, with a greater chance when you hit it in melee. The explosion obviously also causes multiple random vapor effects to the area, and scatters potions around (by throwing them, so they tend to smash if they hit anything).

When potions break on the ground, they leave puddles of that potion. Pets can drink this puddle to get the effects. They also give effects (vapor effects, plus acid burning) to any monster standing in them, which is nice because it makes it harder for the player to stand in one place and fight a horde of enemies. Not defined what should happen if multiple potions mix in one spot - alchemize perhaps.

Vapors from the potion of polymorph should cause a brief or minor polymorph. Possibly the “you feel like a new foo” effect.

Polymorph potions affect all monsters adjacent to where they shatter.

Make more potions effective for throwing at monsters, first by making the vapor effects hit more than just whoever they were thrown at (i.e. splash effects), and then by making more potions have a vapor effect that affects monsters.
