Any good skills for the fire damage sword

I found a unique 2-h sword that only deals fire damage, Oro's Sacrifice Infernal Sword. I'm wondering if there's any skills that can be good with this sword? Am I right to assume that any melee skills that deals physical damage will be pointless with this sword (since it doesn't deal physical damage)?

Thanks

you can use double strike+multistrike, for more elemental damage, you can use weapon elemental damage gem with/or fire penetration maybe

could be better options

the sword has "u take increased physical and fire dmg 20%" which is a pretty bad mod and requires to specificly build a characters defense to adapt to this (u also have no block)

i wouldnt advise a newbie to use it- u gotta love that sword a little to have fun with it i guess

best build for it is this one as far as i know:

i think the creator is also the designer of the unique

You can make a nonstop Flickerstrike build with it too, but I wouldn't recommend for hc. The thing with the ele only damage is to keep the melee skill gem at lv 1, keeps the mana cost down and your not scaling phys damage anyway.
