Aleghaar's Gigantification

You cause a creature you can see within range to grow to the size of a giant for the duration. Choose yourself or a creature within range. If the target is unwilling, it can make a Constitution saving throw. On a success, the spell has no effect.

The target's size triples in all dimensions, and its weight is multiplied by sixteen. 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 attains the maximum possible size in the space available. Until the spell ends, the target has advantage on Strength checks and Strength saving throws, deal double damage to objects and structures, and both its current hit points and hit point maximum increases by 20. Everything the target is wearing and carrying grows in size with it, including its weapons. While its weapons are enlarged, the target's attacks with them deal 1d12 extra damage. Any weapons or equipment dropped by an affected creature returns to normal size at once.
