Elemental Weapons

[the Langolier]

Well, when two people are dueling, they usually agree upon the rules before hand, so it is unlikely it will be considered dishonorable until that issue is specifically discussed. Either way, the elemental damage on weapons is nearly negligable. The only weapon that would do noticable damage would be Schaffer's Hammer (1-50 lightning damage). Even this is very small when you consider maximum lightning resistances and the PvP penalty.

On a side note, warriors actually have quite an easy time hitting their opponents. Most warriors will have enough dexterity for perfect blocking; along with a kings/strange weapon, they have plenty of to-hit to keep an opponent in block lock.
