I just tested the script, and i do like it but here is some feedback:
1: I dont like you use the ` as a trigger part, since it for me, takes to long to write instead of just a . or , -

2: i think you should have made it multi channel like
on *:text:blabla:%ChanSet: {
and the use ascii 44 as a seperator for channels
that will allow the fighter bot to be played in more then 1 channel, but still with the same acc :)

3: Buy Potion and Sword... is that it? then there is alot better bots on the market mate.

4: The colours make it hard to read.. and they realy looks like the colours a 5 year old would pick for painting...

5: You should have added all the cha files in a FOIlder instead of in $MircDir adter 20 min with advertsing for your bot, my FOlder was full... realy sucky..

but when all that has been sayed, its a realy nice bot actually :)
