Talk:Wisp in a Bottle/@comment-8790772-20131009052017/@comment-5404320-20131009060616

If you want an easy one just get a water candle (maybe even a battle potion), place a long, thin strip of lava on the ground and stand in a bunker that's directly above your lava. The mobs will stand in it whilst trying to reach you and slowly die, however be careful of the spirits when they spawn.

I killed the paladin a few times like this because I'm too weak to take him and in the midst of it I got the wisp from passing skeletons.
