How much Damage would a Lightsaber do in D and D?

[hamishspence]

Under these rules, lightsabres allow you to plow through mooks (people who are much lower-level than you, thus giving you the large damage bonus against them), but will still give you a good, drawn-out combat against somebody of equal level to you. Just like the movies. Using relative damage ensures this, rather than using absolute damage values.

It'll also give a fairly short combat against something vastly higher in Hit Dice than you.

Using the aforementioned rules, one could, say, fly into a space slug, start stabbing at its insides, and it'll be dead in 10 rounds.

The Wookieepedia explanation for lightsabers being extremely hard to control, is that "they generate a gyroscopic effect, requiring considerable strength and dexterity to control"

Except- Luke (who's never used a lightsaber before) doesn't seem to have much trouble in A New Hope, both when swinging it after Ben hands it to him for the first time, and the training exercise on the Falcon.
