What is "Lost Mace of Corswain"?

[Runeclaw]

How will the stats be for for this exclusive mace? It is not uncommon for pre-order exclusives to have very powerful stats, making other items and loot almost worthless for a large part of the game.

Will we be able to just transfer the skin of this mace to something else?

Are we free to equip it for both single player and the co-op?

The ganeplay trailer had a power mace of different variety. I bet its a cosmetic change with perhaps some minor stat adjust.

Corswain is a Champion of the Dark Angels chapter during the Horus Heresy this is his mace.

Also the image says start the game with the item not that its exclusive. Meaning you can use it from the get go in the begining instead of finding it ingame. I don't know if you have to take a storm shield as a mandatory with the weapon.

The mace is a relic from Warhammer, and was one of the major plot McGuffins from Space Hulk Deathwing's prequel series, Garshasp, based on a Warhammer novel of the same name by C.L. Werner. The mace became the property of Corswain after Garshasp killed an ork overboss named Trit in combat, and he gifted it to the paladin's family to defend themselves during the endtimes.
