Giant Size (5e Spell)

This content deviates from 5th edition standards. Its use could dramatically alter campaigns, take extreme care.

Caution - Here there be monsters! This content intends to provide a different experience, or goes beyond the scope of the anticipated subjects and situations, than the 5th edition rules were intended to handle. Some portions of the content below may not be what you expect from traditional game content. When implementing this content, DMs and Players should read over all the information carefully, and consider the following specific notes of interest:

This spell allows creatures to grow to sizes larger than Gargantuan, the largest size category in 5th edition, if used on a sufficiently large creature and/or the spell is cast at a higher level. If necessary, it is suggested that this larger size simply be named "larger than Gargantuan."
Additionally, there has been concern that disruptive players may attempt to abuse this spell, by using their much larger size to stand on, sit on, crush, etc. a smaller creature. If a disruptive player attempts to abuse this spell in such a manner, it is suggested that the DM shut this down by citing the game rules, because the rules do not have any provision for a larger creature attempting to crush a smaller one outside of a specific monster having a crush attack.

Giant Size

5th-level transmutation

Range:	30 feet
Components:	V, S, M (a dragon's scale or a giant's hair strand)
Duration:	Concentration, up to 1 minute

You cause a willing creature within range to grow to a much larger size. The creature's size quadruples in all directions, and its weight is multiplied by 64. This growth increases its size by two categories — from Medium to Huge, for example. If there isn't enough room for the target to quadruple its size, the target 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 can treat a d20 roll of 9 or lower as a 10 for Strength checks and Strength saving throws.

Everything the creature is wearing or carrying changes size with it. Any item dropped by an affected creature returns to normal size at once. The target's weapons also grow to match its new size. While these weapons are enlarged, the target's melee attacks with them deal 2d6 extra damage, and the weapon's reach increases by 5 feet.

At Higher Levels. When you cast this spell using a spell slot of 7th level or higher, the creature's size doubles again in all directions (for a total of 8 times the creature's original size), its weight is multiplied by 8 again (for a total of 512 times the creature's original weight), and its size increases by an additional category (for a total of three categories larger than the creature's original size). When the target makes a Strength check or Strength saving throw on which it has advantage, it rolls the d20 three times instead of twice. The extra damage granted by this spell increases to 3d8.

When you cast this spell using a spell slot of 9th level, the creature's size doubles again in all directions (for a total of 16 times the creature's original size), its weight is multiplied by 8 again (for a total of 4096 times the creature's original weight), and its size increases by an additional category (for a total of four categories larger than the creature's original size). The extra damage granted by this spell increases to 4d10, and an affected weapon's reach increases by an additional 5 feet, for a total of 10 feet of extra reach.
