One of the classes I thought was really cool from Revised Dungeons & Dragons was the Lurk. It was a class whose flavor I liked — it was in essence a psychic rogue who made extensive use of the Psionic Focus mechanic to charge his Sneak Attack and power a couple class features. Unfortunately, it just didn’t work.

Psionics in Dungeons & Dragons have traditionally been a weird alternative to magic. For some reason, TSR and WotC have always treated psionics as an aberration, even going so far as to associate psionics with aberrations (aboleths, mind flayers, etc.), and make up insane new rule systems to govern them — like power points.

Here’s my Lurker class for reference:
Essentials Dungeons & Dragons Lurker Class (v0.1)

I’d like to call the Lurker an “Essentials Monk.” You’ll notice it only has 1st-level class features, and that’s because I didn’t want to invest too much time in developing the class, since I have other stuff on my plate. The class contains not only innovations to the role system codified in Essentials, but a few of my own.

The focus of the Lurker is the Cloud Mind power. This is inspired by The Shadow (as I’m sure the 3.5 psionic power was) and enables the Lurker to gain and maintain Combat Advantage against enemies, helping to compensate both for his lack of an inherent accuracy bonus and boost his otherwise low defenses.

Having quasi-permanent invisibility against one creature (two at paragon, three at epic), that can be recharged and thus reused — isn’t really such a powerful ability, even when used against a solo creature. The Lurker receives no accuracy bonuses (though his psychic array targets NADs), and must instead rely on Combat Advantage.

There are a host of feats to expand the use of Combat Advantage, which is why the Lurker doesn’t explicitly gain extra bonuses. Instead he has to make due with invisibility, flight, and a bunch of handy urban skills (Stealth, Streetwise, Thievery).

I also included an “invisibility” keyword, to act as a sort of pseudo-replacement for the illusion keyword. I’m of the mind that 4e doesn’t have much of a use for the more abstract schools (evocation, enchantment, necromancy) of previous editions, when it did such a good job of codifying energy and effect types.

I hope to make greater use of Charm, Fear, Invisibility, Stance, and more … in future experiments.
