Can anybody tell me how can I use dual shield with oathkeeper?
No, because you cannot dual wield shields.
You need to check this 
are you talking about this??? https://www.youtube.com/watch?v=fsM6VUK82qw
And you need to check my post above 
And you need to understand that is not an oathkeeper only thing. That mace can be held by any char and you can use its illusion on any 1handed melee weapon.
and I am allergic to that malagant dude xD
I’ll try this let’s see.Thank your helping 
it is actually a decent weapon. I use it now on my Blade Arc Spellscourge set Warlord.
Is malagant in any way shape or form related to malawiglenn
nope but people call him “mala” too and that bugs me like crazy :furious:
he looks pretty skinny, I am the TRUE GD-stashing Barbarian beef!
What’s the name of that shield/mace thing again?
Totally normal shield 
You have no idea how happy this discovery makes me. I may not be able to be the Juggernaut in GD, but I can pretend to be one. :rolleyes:
