there are many goods sword you can fine in adventure quest like bad ax you can buy them in na store named yougar weapon shop and many more shops
I use the Lucky Sword but the Bejeweled Blade is also good
just go to the light temple
any weapon just enchance and you'll be good
Thunder trolls are OK. Big clone's are fairly good.
the best weapong to buy on AQ Worlds would probably be the thr rune sword or the dark crystal clyamore
these quests are fairly easy and the AI in this game are as strong as you are so the you can be any lvl and still have a good chance for success
you can get it from a good shop but you have to be on the good side
adventure quest worlds is good adventure quest is more like shadowtale hope this helps :D
Talk to the king
Change it Again and again you will be good or evil ^^

there is no "best sword". well if u want a good sword design then just keep on exploring lore until u find a shop that is suitable for u and if u want a strong weapon then even a default sword can be lore's strongest sword! how? its east just keep on leveling up and keep on putting fighter or luck enchancments on your weapons! hope it helped ;)
