Combat Style Advantages: There are three types of attack style that you can choose Dofus Kamas from when pking. These are ranging, maging, and melee. They each have their own advantages and disadvantages over one another.
Pretend to lose and after about 3 rounds, head north to where your friend is positioned (take this time to recuperate if need be).
Your opponent will most likely follow you because he/she knows that you are close to dying, and plus, the only way out of the wild is southward.
Pass north near your friend and when your opponent passes through the same trail, have your friend attack him/her. He’ll surely lose because of the drastic combat level difference and you can heal yourself and assist your friend if the other player is putting up a decent fight.
With a poisonous weapon, your opponent will constantly receive damage from the poison, even if he/she is already out of the wild.
The only way to cure this effect is by using an ant poison potion. The Weapon poison potion can only be used on 10 throwing arrows/darts/throwing knives/throwing axes/javelins, a dagger, or a spear. Remember, only members have this special benefit.
