I am running Legacy of the Crystal Shard this weekend and I have been updating the various monster stats. However, my Monster Manual has not yet arrived.

Can anyone help me out with the Wererat stats? I know the MM has them.

Medium humanoid (human, shapechanger) lawful evil

AC: 12
Hit points: 33 (6d8+6)
Speed: 30 feet

Str 10 (0)
Dex 15 (+2)
Con 12 (+1)
Int 11 (0)

Cha 8 (-1)

Senses: darkvision 60 ft (rat form only), passice Perecption 12

Shapechanger: The wererat can use its action to polymorph into a rat-humanoid hybrid or into a giant rat, or back into its true form, which is humanoid. Its stats other than its size, are the same in each form. Any equipment it is wearing or carrying isn't transformed. It reverts to its true form if it dies.

Keen smell: The wererat has advantage on Wisdom (Perception) checks that rely on smell.

Actions

Multiattack (humanoid or hybrid form only). The wererat makes two attacks, only one of which can be a bite.

Bite (rat or hybrid form only). Melee weapon attack. +4 to hit, reach 5ft, one target. Hit 4 (1d4+2) piercing damage. If the target is a humanoid, it must succeed on a DC 11 Constitution saving throw or be cursed with wererat lycanthropy.

Shortsword (humanoid or hybrid form only). Melee weapon attack: +4 to hit, reach 5ft, one target. Hit 5 (1d6 +2) piercing damage.

Hand crossbow (humanoid, hybrid). Ranged weapon attack: +4 to hit, range 30/120ft, one target. Hit 5 (1d6+2) piercing damage.
