Does a 100% poison wep or 100% fire wep or other 100% wep do any good in pvp or pvm?

What does a wep with 100% sumthing do?

The damage done is based on your skill in using the type of weapon, the damage increase you have whether it's di on the weapon of by another skill such as honoring from bushido, any special move attacks, any slayer attributes on talismans or weapons like reptile slayer, and the opponent's resistance to physical, poison, fire, cold, or energy damage. Thus if you are gm swords with high tactics, anatomy, 65+ chivalry, and are using a 100% fire sword on a fire resistant red dragon, your results won't be as good as if you were fighting a white wyrm with very little fire resist.
