Do not trust your tooltip dps in poe. Ever
I suggest you try out path of building instead
Hoi allows you to use curse on hit but it's less dmg. Hoa doesen't actually hit so cant support curse on hit.
If you are slayer dmg on full life is your best 6th link.
PoB doesn't support the "xx% of phys dmg as extra damage of a random element".
However you can change this by editing the item and just changing the wording to "xx% of phys as extra *insert the ele type you want so --> cold/fire/light*"
Assuming you don't have any ele penetration to a single element that is.
For example here is my current build in pob
https://pastebin.com/2gaFt3e1The sceptre I use actually has 29% phys dmg as random element, but I changed it to cold damage so that I can see the proper dmg.
e/ there is check for update button in the bottom left corner in pob btw, check out that you got the new version since the old ones didnt support even the regular "phys as extra ele mods"
So Melee Damage on Full Life actually works, even if my life stays at ~8 life below full? I'll check that out as well.
