Pathfinder 1e Monster / NPC: Advanced Giant Venomous Snake

Countless species of poisonous snakes dwell in the wild, their bites capable of bringing down creatures much larger than themselves. Snakes of the size presented here are thankfully rarer than their smaller kin, but many species of rattlesnake, cobra, and similar reptiles can grow to this size.   Venomous snakes are generally far more aggressive than constrictor snakes, and even large variants like this one, do exist: This one for example, is made by applying the advanced and giant simple templates to the stats given in Bestiary pg 255.   (Weapon finesse feat traded away for Improved Grapple, as the original feat was based on low strength and high dex, but the templates made strength surpass dex. I also just made a GM ruling that it does not count as grappled when grappling an enemy, due to it's long body, and that it can grapple with the "mid or lower" section, and still melee attack unhindered)
