Weremoose

A weremoose can communicate with deer, including moose.

The weremoose treats environmental cold effects as if they were one step less extreme.

Medium human with fist +11 for 1d4+6 bludgeoning, or Large moose with antler and hoof +11 for 1d8+6 bludgeoning. The monster changes its shape indefinitely. It can use this action again to return to its natural shape or adopt a new shape. Unless otherwise noted, a monster cannot use Change Shape to appear as a specific individual. Using Change Shape counts as creating a disguise for the Impersonate use of Deception. The monster's transformation automatically defeats Perception DCs to determine whether the creature is a member of the ancestry or creature type into which it transformed, and it gains a +4 status bonus to its Deception DC to prevent others from seeing through its disguise. Change Shape abilities specify what shapes the monster can adopt. The monster doesn't gain any special abilities of the new shape, only its physical form. For example, in each shape, it replaces its normal Speeds and Strikes, and might potentially change its senses or size. Any changes are listed in its stat block.

This curse affects only humanoids. Saving Throw DC 17 fortitude On each full moon, the cursed creature must succeed at another Fortitude save or turn into the same kind of werecreature until dawn. The creature is under the GM's control and goes on a rampage for half the night before falling unconscious until dawn.

When a full moon appears in the night sky, the werecreature must enter hybrid form, can't Change Shape thereafter, becomes one size larger, increases its reach by 5 feet, and increases the damage of its antlers by 2. When the moon sets or the sun rises, the werecreature returns to humanoid form and is Fatigued for 2d4 hours. Effect: Moon Frenzy

The weremoose Strides twice and then makes an antler Strike. A Medium or smaller creature damaged by this attack must succeed at a DC 17 fortitude save or be Stunned 1.
