open prefix, what to do?

Bought that sword, noticed it has an open prefix.



On the bench, I could add
"gain 15-18% of non-chaos damage as chaos"
"hits cannot be evaded"

Adding a veiled mod is nonsense, right?
(Do I not get all the veiled mods in my crafting bench anyways?)

There's no "hybrid %phys" mastercraft anywhere taht I maybe missed a recipe for, right?

If you are crit I would go with hits can't be evaded

But that's also the 3 Ex option, compared to a couple vaal orbs. ;)

PoB tells me that both options I listed above are roughly equal for my character in its current state (1.1 million vs 1.05 million dps on cyclone).

I just want to make sure that (lucky exalt slam aside), I'm not missing some obvious mastercrafting solution to increase the sword's base dps.
