Colossal Growth

You target a creature within range, causing them to undergo a rapid and incredible transformation. The target's size doubles in all dimensions, and its weight is multiplied by eight. This growth increases the creature's size category by one—up to a maximum of Gargantuan—and it gains the following benefits:

• Increased Strength: The target's Strength score increases by 4, up to a maximum of 30. It has advantage on Strength checks and Strength saving throws.
• Expanded Reach: The target's reach increases by 10 feet.
• Increased Damage: The target's weapon attacks deal an additional 1d8 damage.
• Intimidating Presence: The target has advantage on Charisma (Intimidation) checks.

If there isn't enough room for the target to grow to its new size, it attains the maximum possible size in the space available. The target also gains temporary hit points equal to its new size category's hit die (e.g., 12d12 for Gargantuan size).

At Higher Levels:

When you cast this spell using a spell slot of 7th level or higher, the duration increases by 1 minute for each slot level above 6th.

Note: The spell's effects end if the target is reduced to 0 hit points or if the caster loses concentration. When the spell ends, the target returns to its normal size and loses any temporary hit points granted by this spell. Any objects worn or carried by the target return to their original size when they leave the target's possession.
