(somatic, verbal)
Range 30 feet
Target you and up to 5 willing targets
Duration 1 minute

Summoning the power of the natural world, you transform the targets into a herd of mammoths, and they each assume a Huge battle form. Each target must have enough space to expand into or the spell fails for that target. Each target gains the animal trait. Each target can Dismiss the spell's effects on themself. Each target gains the following while transformed:

AC = 22 + the target's level. Ignore any armor check penalty and Speed reduction.
20 temporary Hit Points.
Speed 40 feet.
Low-light vision.
The following unarmed melee attacks, which are the only attacks the target can use. They're trained with them. When attacking with these attacks, the target uses their attack modifier with the proficiency and item bonuses of their most favorable weapon or unarmed Strike, and the damage is listed for each attack. These attacks are Strength based (for the purpose of the Enfeebled condition, for example). If the target's unarmed attack modifier is higher, they can use it instead. Melee tusk (reach 15 feet), Damage 4d8+19 piercing; Melee trunk (agile, reach 15 feet), Damage 4d6+16 bludgeoning; Melee foot (agile, reach 15 feet), Damage 4d6+13 bludgeoning.
Athletics modifier of +30, unless the target's own modifier is higher. You move up to twice your Speed and move through the space of Large or smaller creatures, trampling each creature whose space you enter. A trampled creature takes damage from its foot Strike based on a basic Reflex save (DC = 19 + the target's level).

Traits

Common

Anything that doesn't list another rarity trait (uncommon, rare, or unique) automatically has the common trait. This rarity indicates that an ability, item, or spell is available to all players who meet the prerequisites for it. A creature of this rarity is generally known and can be summoned with the appropriate summon spell.

Transmutation

Effects and magic items with this trait are associated with the transmutation school of magic, typically changing something's form.

Polymorph

These effects transform the target into a new form. A target can't be under the effect of more than one polymorph effect at a time. If it comes under the effect of a second polymorph effect, the second polymorph effect attempts to counteract the first. If it succeeds, it takes effect, and if it fails, the spell has no effect on that target. Any Strikes specifically granted by a polymorph effect are magical. Unless otherwise stated, polymorph spells don't allow the target to take on the appearance of a specific individual creature, but rather just a generic creature of a general type or ancestry. If you take on a battle form with a polymorph spell, the special statistics can be adjusted only by circumstance bonuses, status bonuses, and penalties. Unless otherwise noted, the battle form prevents you from casting spells, speaking, and using most manipulate actions that require hands. (If there's doubt about whether you can use an action, the GM decides.) Your gear is absorbed into you; the constant abilities of your gear still function, but you can't activate any items.
