Item made with Echo Shards that revives a slain Pet or Named-Mob

Something that a lot of players find sad is when a mob they're attached to is slain, either through a tragic accident or the mob being stupid and walking into a cactus.

So what if there was an item that could respawn them, just like a player can?

Crafted using echo shards (since they have something to do with souls) and possibly soulsand, using it can let you choose which of your mobs will be revived right in front of you, or around a connected structure.

This way, players have a fallback just in case a mob they're attached to dies and they want them back since getting a new one wouldn't be the same.
