When Duergar cast this spell as a racial ability, it can only be cast once per Long Rest.
Enlarge increases the target creature's size to the next higher category. For example, a Medium creature becomes Large. This also increases the scale of the creature's model by 33%.
Enlarged creatures can Shove significantly heavier objects. Refer to max shove weight for details.
On the other hand, Enlarge does not affect the weight of objects that can be Thrown or wielded as a Improvised Melee Weapon.
Enlarge also increases the weight of the target creature to 2.35 × original weight. If the new weight is below the minimum weight of the new size category (e.g. 200 kg if increased to Large), the weight is set to the minimum value for that category. See Creature Size for more information.
Unarmed Strikes are affected by Enlarge.
As of Patch 3, the Duergar version of Enlarge notably does not require Concentration.
The incantations for Enlarge are Gigans ("Giant") and Extende ("Extend").
