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

[hamishspence]

But that's generally a high level one- not a 1st level character.

For a weapon that can fairly rapidly kill anything in the game, to able to do this in the hands of even a low level character (if every strike hits) seems a bit OTT.

If you want a G-canon character, not force-sensitive, who is able to wield a lightsaber in battle without damaging himself- how about General Grievous?

As to the "in-combat" thing- the fumbling rules you listed said "when attacking with the weapon"- but whenever an object is attacked, even if the object can't move or attack back the player will be making an attack roll.

Using your rules, even if Han was attacking an object (like the corpse of a tauntaun) he would still have a chance to fumble and injure himself.

Which seems a bit excessively severe.
