Some weapons and spells cause elemental statuses, such as being poisoned, slowed, or frozen. When under such an effect, the enemy will display an effect, such as glowing green when poisoned or being covered in ice when frozen. Any enemy that dies during one of these effects will qualify for "Relieve the pain". To farm this, find a Serpent Staff. It has a 100% chance to inflict the poison status upon a hit. Progress until you encounter the shaman Boss or random shaman enemies. Shamans can summon extra enemies indefinitely, especially carrots. Hit a carrot with a single bolt from the staff will usually leave it poisoned until it dies shortly afterwards. Continue killing carrots spawned by shaman in this manner until "Relieve the pain" is earned.
