Flasks created with Alchemy are a type of elixir. Some non-drinkable flasks are quest items or ingredients used in other professions, such as Engineering and Leatherworking. Some flask recipes may be purchased from various faction vendors and then traded to another character, however they will not be able to learn the recipe without also having the required faction.

Flasks count as both a Battle Elixir and a Guardian Elixir, so characters can only have the effect of one flask at a time, and it prevents them from having other elixir effects. Flasks have a cooldown of 3 seconds, and except for [Flask of Petrification], all have a duration of 2 hours. These flasks are created by Alchemists, and require an Alchemy Lab. Alchemy Labs are located in Shattrath City, in Scholomance near Ras Frostwhisper and in Blackwing Lair past Broodlord Lashlayer. Flasks are different from potions and elixirs in that their effects do not disappear upon death and cannot be dispelled.

Flasks benefit from the Elixir Specialization.

Additional info:

• Elixir - Similar to potions with differing effects that have mostly longer durations.
• Potion - Similar to elixirs with differing effects that are mostly instantaneous or have short durations.
