If I ever wind up in your 3.5Ed game, I will play a Soulknife, just for spite.![]()
I think if anything this thread would seem to indicate that mechanically no-one knows and few people have a strong opinion either way (except [MENTION=85158]Dandu[/MENTION] who straight decides "Yes" with no real explanation or evidence).
Mind Blade (Su)
As a move action, a soulknife can create a semisolid blade composed of psychic energy distilled from his own mind. The blade is identical in all ways (except visually) to a short sword of a size appropriate for its wielder.
I'm confused by the original question. Are you asking if being attacked by the soulknife's blade leaves behind cuts?
If so I'd say yes.
Unless I'm wildly missing the point a soulknife is basically Psylocke (from xmen). I assume her blades cut too.
But perhaps I'm missing something.
It'll hurt you more than me, mate.
I guess for the prospect of the soulknife in the story i'm planning on that it doesn't leave a mark as it is a story...
