Mossy Mammoth

Preserved for thousands of years in stone, bronze magic has nearly aged this mammoth back into a fossil.

Riding Requirements:

This mount is available to all eligible characters on your account.
Level 10
Apprentice Riding

Notes:

This green-haired mammoth can be obtained in the Forbidden Reach by progressively combining a number of items that can be obtained from Zskera Vaults. You unlock these vaults during the zone intro quest chain, and obtain vault keys mostly from defeating rare NPCs in the zone.

The item sequence is:

Obtain a Scrap of Black Dragonscales and a Strange Petrified Orb from chests in the Vaults, and combine them to create a Particularly Ordinary Egg.
Obtain a Drop of Blue Dragon Magic from the Vaults and combine it with the Particularly Ordinary Egg to form a Magically Altered Egg.
Obtain Everburning Ruby Coals from the Vaults and combine it with the Magically Altered Egg to form an Egg of Unknown Contents.
Obtain a Speck of Bronze Dust from the Vaults and combine it with the Egg of Unknown Contents to form a Sleeping Ancient Mammoth.
Obtain an Emerald Dragon Brooch from the Vaults and combine it with the Sleeping Ancient Mammoth to create your Mossy Mammoth.

Note that the Speck of Bronze Dust and Emerald Dragon Brooch seem to come from much later vaults, which will require clearing one vault a week for several weeks.
