it works in r4-5 but kinda ded in r3-1, use a res drain instead of sorrow because you'll need more resitance drain, put a hp kit can help you survive longer while fighting energy mechs, be careful with huggers tho
this should be question, however, if you don't have relics, use it to upgrade another items.
300k for crafting, 200k for upgrading and 500k for transforming your top weapon to divine
if you aren't using base, buy sliver boxes and don't enable it
don't spend to much coins for transforming e-m to divine if you're in low-mid rank, it's a lot of gold wasting
