Buy Price: 600 Tenacious Tentacula that when deployed shoot acid at nearby enemies. Venomous Tentacula seeds can be purchased at Dogweed & Deathcap. Must be grown in large pots.
Where to Find Venomous Tentacula
Venomous Tentacula can be acquired in three ways: you can either buy it as is from vendors, buy Venomous Tentacula Seeds from a shop in Hogsmeade and plant them in your Room of Requirement, or gather Venomous Tentacula from a secret place with slow but infinite respawns (see section below)!
To grow Venomous Tentacula you will need to acquire the seeds from the Dogweed and Deathcap shop in Hogsmeade. Incidentally, the same shop will give you the option of buying Venomous Tentacula as a plant that can then be directly used from the Tool Wheel. Though, there are other stores that will offer you the latter option as well.
Once you acquire the Seeds, all you have to do to grow Venomous Tentacula is plant them in a Large Pot at your Potting Table.
Herbology Wing Venomous Tentacula Farm
There is one additional way to get Venomous Tentacula that can be accessed very early on. However, this particular spot has a very long respawn time; still, you can pick up around 5 free Venomous Tentaculas with each respawn, and that will be extremely helpful early on, especially if you haven’t unlocked the Room of Requirement yet.
The location is in the Herbology Wing of the Castle.
