Solved Act 5 Mercernaries

Hey, so recently i've been wanting to improve the speed of travincal runs with my gold find barb and so i was wondering can the axe mercenary (combat) dual wield axes? and if not Does it just double the dmg by replicating the axe on his 2nd hand? i heard once that if you equip 1 Lawbringer on a Sword mercenary it Doubles the aura idk if this is true tho as it might be a bug of sorts altho i feel it would just be fair because being capped to Axes/Swords with such few good weapons/runewords to equip its hard to make a good combination with other characters

my theory is to equip 2x Eth Kingslayer berserker axes or 1x with double the dmg or something like that if not then i guess i go back to act 2 mercenary or try Destruction/Grief in a Ethereal Colossus Blade/Sword, im trying to avoid any kind of cold damage as even 1% cold dmg could pop the bodies and i reallly don't like it when they do that

Edit: i might have asked this before but my memory is really bad and i don't really know how to navigate through the forums to find questions like these its a tiny bit hard as when i search something its not in the title and that leaves me stranded

 

as in it does replicate the axe in the second hand or is it similar to when you don't give a weapon to your mercenary at all?

 

Thanks, thats all i wanted to know
