The cursed Ivory Shredflesh is available after the Fairy Tale III - Orks RiftQuest in the area where you banished the Fairy Godfather. Southeast of the fairy ring are a few of them who won't attack back, however they are surrounded by ones that are aggressive. They are very profitable to kill, fairly often dropping high value seeds and dragon daggers. The easiest way to kill these is to kill 1-2 shredfleshes anywhere in the cave and then spawnkill them south-east of the fairy ring.
If you kill the Shredflesh of certain groups of statues, namely the groups north/north-west of the fairy ring, they will respawn at the farming patch near the fairy ring and be trapped. This allows you to solo Shredflesh statues one on one without interference from other statues.
On the day of release, Ivory statues dropped 3 charms at once, with a very high gold percentage. On 14 May 2010 (the day after release) there was a hidden update which altered the drop rate to 1 charm per drop, and also altered the ratio of the different colours of charm drops.
