The Shattered Lands
Eggs of Ash and Myrrh
Wondrous item, Very Rare
This golden egg inlaid with reddish-brown stone is about the size of a human fist and is crafted to appear like the egg of a phoenix. Warm to the touch, the egg glows a golden color (shedding light as a torch) and functions as a holy symbol for clerics of the light domain. The light from the egg can be covered or hidden, but not smothered or quenched.
If you use an action to speak a command word while holding the egg, it opens and emits a fragrant red smoke which ignites into the form of a small phoenix. The creature is friendly towards good aligned summoners, and their companions. It understands all languages, and obeys the spoken commands of its summoner. It will immediately attack evil summoners, and ignore the commands of neutral ones. If you issue no commands, the creature defends itself but takes no other actions.
The myrrh phoenix exists for 8 hours after which it burns away into a pile of ashes and myrrh. It burns out early if it is reduced to 0 hit points or if the summoner speaks the command word again. When the phoenix burns out, its ashes must be placed back into the egg for 6 days and anointed with holy water before it can be summoned again.
