Wouldn't it be great if there was an achievement or some other badge of honour type thing... For giving another slayer their very first death. Especially... With a name like this-
Have you ever heard of a thing called a "joke" ? Learn this word, and hopefully, in time... Lern2use them. With a name like "The Death Taker" i found it rather funny to be giving him his first death, although you're right. Clearing your fightlist with the hitlist is a lot of fun and is so easily done at low levels. Any badge of honour would have to be for killing anyone asking for it (like this) with your own (clenched) hands!
Don't worry about it kidder... I'm sure you will give someone their very first death one of these days, just keep trying!
