Whatcha gonna do when Maulermania runs wild on you, brother? Reaping maulers are grappling savants, adept at not only at grappling people their size but especially against people or creatures that are significantly larger than them. This is a perfect gremlin/goblin class, where if you just wanna be that hard to kill annoying little spitfire who just keeps getting in people's faces and artfully disrespects their defense by dragging them kicking and screaming into your awful little Baatorian landscape of pain, this is the class for you. They can eventually knock people unconscious and even instantly kill people with their grappling prowess. I love this class and it's perfect for shutting down most spellcasters and just being a wee little beastie.

Class Features
All of the following are class features of the Reaping Mauler.
Weapon and Armor Proficiency: A Reaping Mauler is proficient with whatever they were already proficient with
Improved Grapple Ex: When wearing light armor or no armor, a reaping mauler gains the benefit of the Improved Grapple feat, even if he does not meet the prerequisites.
Mobility Ex: When wearing light armor or no armor, a reaping mauler gains the benefits of the Mobility feat, even if he does not meet the prerequisites.
Adept Wrestling Ex: Beginning at 2nd level, a reaping mauler who is wearing light armor or no armor gains a +1 bonus on all grapple checks and opposed Dexterity or Strength checks. This bonus increases to +2 at 4th level.
Counter Grapple Ex: When grappling or pinned, a reaping mauler of 3rd level or higher wearing light armor or no armor can attempt either a grapple check or an Escape Artist check opposed by his opponent's grapple check to free himself as normal. If he fails the check he has chosen, he can immediately attempt the other check as a free action.
Sleeper Lock Ex: At 3rd level, a reaping mauler learns how to render an opponent unconscious with pressure. If the character pins his opponent while grappling and maintains the pin for 1 full round, the opponent must make a Fortitude save (DC 10 + the reaping mauler's class level + the reaping mauler's Wis modifier) at the end of the round or fall unconscious for 1d3 rounds. A creature with no discernible anatomy has immunity to this effect.
Devastating Grapple Ex: If a 5th-level reaping mauler pins his opponent while grappling and maintains the pin for 3 consecutive rounds, the opponent must make a Fortitude save (DC 10 + the reaping mauler's class level + the reaping mauler's Wis modifier) at the end of the third round or die. A creature with no discernible anatomy is immune to the effect of this ability.
