A popular house rule in Dungeons & Dragons lets characters drink a potion as a bonus action rather than as an action. (See Scrutinizing the 9 Most Popular House Rules for D&D.) When a typical round takes several minutes of real time to play, this rule spares the players from having to wait for their turn only to spend it adding 2d4+2. That turn feels like a letdown.
Nonetheless, I favored playing by the book and making drinking a healing potion an action. Until we welcome CamelBak hydration backpacks into our D&D worlds, I estimate that getting and opening a vial, and then downing the contents would take the better part of 6 seconds. Also, characters tend to need healing potions late in a fight, and I enjoy the difficult choice between pressing an attack despite dangerously low hit points or healing. Choices make games engaging.
My opinion changed after I played countless battles while eyeing unused potions of giant strength, fire breathing, and heroism in my characters’ inventories. Near the end of a battle, I still like the dilemma that healing potions can bring, but those other potions work best as a boost at the start a tough fight—the sort of fight you never want to begin by wasting a turn sipping a potion. The typical D&D battle only lasts three rounds!
Can I start fights with a timeout? “Before we roll initiative, my character tells the dragon, ‘Wait one second,’ holds up a finger, and then drinks a potion of fire resistance.” Until that works, I will continue to retire characters with stockpiles of unused potions. I would have enjoyed using those potions, so I suppose I’m ready to invent a device that rigs one of those gag cup-holder hats with more tubes than a pan flute.
