Ekans (3.5e Monster)

Combat
 (Su): An Ekans unsettles foes with its mere presence. The ability takes effect automatically whenever the Ekans attacks, charges, or constricts a victim. Creatures within 60 feet are subject to this effect if they have less HD than the Ekans. A potentially affected creature that succeeds at a Will save (DC 10 + 1/2 HD + Charisma modifier) is immune to the frightful presence for one day. On a failure, the creature is frightened for 4d6 rounds.

 (Ex): To use this ability, an Ekans must hit with its bite attack. If it maintains a hold for an entire round, it may constrict.

 (Ex): Every round an Ekans maintains its hold it inflicts an amount of damage equal to its normal bite damage as bludgeoning damage - which may be inflicted as regular or nonlethal damage at its option.

 (Ex): Bite, (DC 12 + 1/2 HD + Con Modifier) initial and secondary damage 1d6 Strength.

Skills: Ekans receive a +4 racial bonus to Hide, Listen, and Spot checks and a +8 bonus to Balance checks. They can use Strength or Dexterity for Climb checks, whichever is better.
