The Elder Wand is a gamepass item in Magic Training purchasable for 1500 Robux. This gives the buyer the advantage of equipping a more powerful wand, which triples the uses of most spells (excluding Bombarda and Baubillious, which only get double the casts) as well as access to three new area of effect spells: Infernum, Pruina Tempestatis, and Protego Diabolica.

It is known that it is highly difficult to defeat a player with an Elder Wand when clashing due to the increased rate of which the white orbs instantiate. Another advantage of the wand is the significantly shortened delay between blocking (Q).
The Elder Wand can be stolen from its user using the Disarming Charm, Expelliarmus as well as the Revulsion Jinx, Relashio. If the same Elder Wand is disarmed twice from two different people, it will not be able to cast spells anymore; the Elder Wand will be completely disabled. Returning the wand to either of its first two users seems to reactivate it, however -- at least, until it is stolen again.
An alternative version of the Elder Wand exists, which is accessible by game administrators. This wand takes the form of that of Antitoch Peverells, a character from the official Harry Potter canon.
