Requires: Channelling
This feature is designed and not yet implemented.
A potion is an enchantment reduced to a cell and one glyph, with no gate and no conduit. It discharges once, when drunk. The drinker contributes nothing: the potion's effect is fixed when it is made.
Bottleable effects
Only effects that act on the drinker can be made into potions. Directed effects cannot.
