Soulspeaker

ITEM 2

Price 25 gp

Usage worn

Bulk —

This grotesque, amulet-like shrunken head is said to hold a shard of its owner's psyche. The head is often that of a humanoid, but any creature capable of speaking in life can provide the grisly component needed for this magic item's creation. The head can contain a short message whispered to it and can then be commanded to repeat the message later. While a soulspeaker carries a message, the eyes of the shrunken head open, and they close as soon as its message is delivered.

Activate command

Effect You cast Message, but instead of your message being transferred directly to a target's ears, the message is stored in the soulspeaker. The soulspeaker's eyes open, and the next time it's activated, the soulspeaker repeats the message you spoke to it with a rasping whisper before its eyes close again, the message expended.
