I'Ve heard the fact that keeping a shield in the back helps reducing damage. Does it reduces damage when you take damage to the shield only at your back, or front damage too? Is the power of the shield necessary to get less damage from hits with the shield? (Does a practice shield reduces the same damage that a heather shield, for example? or a heirloomed shield reducing more the damage even if on the back?)
Any links to a post about it if it already exist? can't find it.
Thanks
