Chwidencha

Special Trait Name.   

Spellcasting. The [monster name] is a #-level spellcaster. Its spellcasting ability is [ability score] (spell save DC #, +# to hit with spell attacks). The [monster name] has following [class name] spells prepared:
Cantrips (at will): [spell name], [spell name] 
1st level (# slots): [spell name], [spell name] 

Action Name. Constrict, 3d6 + 9

Action Melee Attack. 4 leg rakes, +10 to hit and +6 to dam 1d6+6/19-20

Constrict (Ex): With a successful grapple check, chwidencha can crush grabbed opponent, dealing 3d6+9 points of bludgeoning damage.

Improved Grab (Ex): If a chwidencha hits an opponent that is at least one size category smaller than itself with at least two leg rake attacks, it deals normal damage and attempts to start a grapple as a free action without provoking
an attack of opportunity (grapple bonus +19). If it gets a hold, it also constricts on the same round. Thereafter, the chwidencha has the option to conduct the grapple normally, or simply use its legs to hold the opponent (–20 penalty on grapple check, but the chwidencha is not considered grappled). In either case, each successful grapple check it makes during successive rounds automaticallydeals rake and constrict damage.

Reaction Name. Leg Regeneration (Ex): Foes can attack a chwidencha’s legs, but only when those appendages are actually holding an opponent. A leg has an AC of 19 (touch 12) and can withstand 20 points of damage. The loss of a leg
does not harm the creature (that is, the damage does not apply against its hit point total), and the chwidencha regrows the limb within a day.

Tremorsense (Ex): A chwidencha can automatically sense the location of anythingnwithin 60 feet that's in contact with the ground.
