Wizard Killing Ability in Silkroad
Although your warrior in Silkroad can go against much higher mobs and not die, its killing ability is much slower than a wizard. There are all flavors of warrior subclasses, check the character guides sticky for details. A wizard should not die against monsters their level Silkroad gold if they play smart. You will have to run up close to a monster to use 4 skills where a wizard only has to use one ranged attack. That means, you stay around monsters that you can one hit. If you can one hit monsters your level, then it should be easy to take down a champion.
Try running back a little bit so that you are at the maximum range for your first book ice spell. Hit the champion with that and if there are no other monsters nearby, immediately follow up with the second book lightning spell to damage sro gold it and keep it away. If there are monsters around, teleport or run since you are a bard away from the champion to keep it from getting close. Then, finish it off with a first book fire spell. Your goal is to keep away from the champion, not stand there taking hits. If you get hit, you are doing it wrong.
