LOD Corpse Explosion Build Iron Rose Stats reroll

I think this is a bad Primal Ancient
Stats are as follows

+485 - 600 Dmg
+1000 Int
+1000 Vit
8% Cool Down reduction
+15% Corpse Lance Damage

Which stats should be reroll ?

I’d say Corpse Lance damage to CHC and it should be OKish.

Not Area Damage instead?

If you already have ~50% CHC in total, you can also use AD.

Thank you.

Grim Scythe vs Corpse Explosion for both LOD… which can go higher in Grifts?

For that I don’t have an answer. Both are powerful.
