You cause a creature or an object you can see within range to grow larger or smaller 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.
• Enlarge: The target's size doubles in all dimensions, and its weight is multiplied by eight. This growth increases its size by one category — from Medium to Large, for example. If there isn't enough room for the target to double 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. The target's weapons also grow to match its new size. While these weapons are enlarged, the target's attacks with them deal 1d4 extra damage.
• Reduce: The target's size is halved in all dimensions, and its weight is reduced to one-eighth of normal. This reduction decreases its size by one category — from Medium to Small, for example. Until
the spell ends, the target also has disadvantage on Strength checks and Strength saving throws. The target's weapons also shrink to match its new size. While these weapons are reduced, the target's attacks with them deal 1d4 less damage (this can't reduce the damage below 1). You gain advantage on Dexterity checks and saving throws.
You grow to a size larger than ever before. You can choose to become Huge or Gargantuan in size. As a Huge character, you gain the benefits of Enlarge, but also gain an additional 1d4 damage and +5 to Strength checks. As a Gargantuan character, you gain another 1d4 damage and +5 to Strength and Constitution checks. After this transformation ends, you gain 1 level of exhaustion if Huge, and 3 levels of exhaustion if Gargantuan.
You become a incredibly tiny. This form grants all the benefits and negatives of the reduced state, but also grant an additional -5 to Strength checks and an additional 1d4 subtracted from attack rolls. This form also grants you +5 to all Dexterity checks.
When a target attempts to hit you, you can shrink and grow in such a powerful expansion, that all creatures within 5 feet are shook. If you are hit by an attack, you can choose to give the target disadvantage by activating this power. If the attack misses, the target must make a Constitution saving throw against the wielder's DC. If they fail, the take 1d8 thunder damage and are knocked prone. On a successful save, they take half damage and are not knocked prone.
