Best way to farm Belly, Remorse, Lion's Roar, ring with Vuln on hit and good pdps siege axe?

Hi All,

SSF newbie here, playing Lacerate. I'm wondering what are the most efficient ways to farm those items in SSFHC:
Belly of the Beast
Lioneye's Remorse
Lion's Roar
Ring with Vulnerability on hit

I guess Siege Axe is more random but there might be some ways to farm a lot of them.
Thanks in advance!

There is really no target farming is POE; closest thing is divination cards.

Belly has a specific divination card; not sure where it drops.
Lioneye's remorse has a couple cards that will drop it, but no specific card.
Lion's Roar can be gotten from Earth Drinker div card. I believe it still drops in Dunes map.
Siege axe - will need a lucky drop or to craft it
Vulrnerability on hit - looks like you need an item level 75+ warlord ring, which you will need to craft.

Honestly good luck with all that, it is going to take awhile.
