I'm on a guild quest to find proof of the leprechaun. I found him, but what am I supposed to do with him? I've tried to speak to him, but he just runs away. I've also tried to kill him, but again he just runs away! Is there any way to stop him???

Isn't that a tease!

Well in fact it is because the leprechaun isn't what you need to fulfill your quest. You need to get through the Sphynx Pyramid to an enclosed area where you can talk to Kerah and also find the Leprechaun's treasure. Inside that chest will be the proof you need for the quest. So forget about Lucky and get on with the game! (you can kill him if you like and get an interesting weapon but he's not hurting anyone, just being annoying)

Thank you!

I'll just try to ignore him then
