Lissok’s Gift of the Overgrown

4-level Transmutation

You cause a creature or an object you can see within range to grow to enormous proportions for the duration. Choose either a creature or an object that is neither worn nor carried. If the target is unwilling, it can make a Constitution saving throw. On a success, the spell has no effect.
If the target is a creature, everything it is wearing and carrying changes size with it. Any item dropped by an affected creature returns to normal size at once.
The target’s size triples in all dimensions, and its weight is multiplied by 16. This growth increases its size by two categories – from Medium to Huge, for example. If there isn’t enough room for the target to triple its size, the creature or object attains the maximum possible size in the space available. Until the spell ends, the target also has advantage on Strength checks and Strength saving throws and gains advantage on all grapple checks it initiates or attempts to maintain. The target’s weapons also grow to match its new size. While these weapons are enlarged, the target’s attack with them deal 2d4 extra damage. Any time the target of this spell makes a successful unarmed attack, they may attempt to either knock prone, grapple or knock the target of their attack away from them by 10 feet as a bonus action.
