For Flame Lurker, having the purple flame shield helps a lot for melee players. One popular way to get the shield early is to kill the dragon in 1-2 in the tower with arrows and go back in 1-1 where the lair is to pickup the now unguarded shield. Also if you put on the thief's ring, you can sneak from the side and get behind the flame lurker without him detecting you. If you have poison cloud, you can then just proceed to stay there and cast and recast poison cloud and be patient or weaken him with rage of the gods. (If your magic and faith is high and you're using talisman of the beast, one or two shots of rage of the gods will get the job done).
