What's up with the Poacher? That sounds like a pretty specific and narrow class. What distinguishes it from the Hunter, for example?
Well, that's part of where I came up with the variant class concept. It's for extremely narrow classes, or NPC classes and such.
Rather than slam and entire class in the book for a niche concept, I take an existing class that's close, and tell you how to "transform" it into the variant.
Since the Poacher caught your eye, I'll use that to illustrate.
Poacher
Poachers are a variation on the Ranger class and conform to that that class in every way except those detailed here. They are enemies of nature and are committed to hunting down its protectors, especially Druids and Rangers.
Alignment: Any evil (Lawful Evil, Neutral Evil, Chaotic Evil)
Damage Bonus vs. Druids and Rangers: Poachers do not gain a damage bonus against humanoids. Rather, they gain a damage bonus against Druids, Rangers and good-aligned Sylvan or Faerie creatures. They might also gain this bonus against other creatures at the discretion of the game master.
Poachers can inflict their bonus damage on clerics and druids with ranged weapons.
Spellcasting (8th): Poachers are antithetical to everything druidic orders stand for and receive no training in Druid spells from such orders, though they gain Magic-User spells normally.
However, Poachers of 8th level and above do receive special training from other Poachers on how to resist Druidic spells and gain a +4 bonus to saving throws against any spell cast by a Druid or Ranger (including Magic-User spells cast by a Ranger).
Poaching Party (10th): Poachers do not receive a special band of followers as Rangers do. However, they do gather like-minded individuals around themselves starting at 10th level if such is their desire.
A poaching party will consist of the following: one follower of one-half the Poacher’s level (always a member of the Poacher class); 1d6 followers of 2nd level (always members of the Hunter class); one 1st level follower for each level beyond 10th gained by the Poacher (50% chance to be a member of the Hunter class, otherwise these are Fighters).
These followers will stay with the Poacher as long as he is in the wilderness. They will stay outside if he ventures into a city, as they are neither comfortable nor welcome in such environments. Should the Poacher spend more than a month straight in a city, his poaching party will disperse and he will have to gather a new one, requiring at least 30 days (more if the Poacher makes a habit of allowing his poaching parties to disperse).
Members of a poaching party that are killed are replaced after 1-2 weeks.
So you can see this is a narrow concept. I don't really think it would be suitable as a PC concept, even in an evil campaign.
