Enlarge Person, Mass

This spell causes instant growth of all allied humanoid creatures in 15 feet, doubling their height and multiplying their weight by 8. This increase changes the creature's size category to the next larger one. The targets gains a +2 size bonus to Strength, a –2 size penalty to Dexterity (to a minimum of 1), and a –1 penalty on attack rolls and AC due to its increased size. Melee and ranged weapons used by this creature deal more damage. A humanoid creature whose size increases to Large has a space of 10 feet and a natural reach of 10 feet. This spell does not change the targets' speed. Enlarge person dispels reduce person.
