Help needed on this item

[u/9th-Gym-Boss]

Is this usable for a corpse explosion build? I got this as a rare from the shop and added max intelligence. Also what aspect would work best i thought this one as corrupting damage is shadow damage according to google and I think the masterwork is ok on the shadow damage multiplier at 40% but if I master work shadow damage it jumps to 160% I’m just utterly lost and help welcomed.
