Giants occasionally generate with a rusty or very rusty two-handed sword or battle-axe, rather than a boulder to throw.

New artifact Sinsword, a chaotic two-handed sword. If your alignment is positive, it behaves just like a regular two-handed sword. If negative, it gains a bonus to to-hit and damage (capped at 6) based on how negative your alignment is. Deals double damage to angelic beings.

Rename the two-handed sword to “greatsword”, moving “two-handed sword” to its unidentified description.
