Appearance and Effects
The spell caster should concentrate on the desired height changes as they tap themselves twice on the head with the wand and repeat the incantation. A desired change in physical build can be achieved by the caster tapping his or herself on the opposite shoulder three times as the incantaton is repeated.
Although the caster will not be able to see any changes in themselves without the use of a specially charmed mirror, the changes will be apparent to other observers.
To end the effects of the Tirinum Charm, the Haniros Charm is used.
