Got a holy greatsword from a void crusade reward with "Enemies explode on kill dealing +50% base damage and shocking enemies in AOE" enchantment, and I have some wild build ideas with it, but I need some clarification on how the mechanic works exactly.

First is the damage part, the wording confuses me a bit. Is it killing blow damage, or weapon base damage? And the +50% part... so I guess that means it's 150% damage?

The other question is the trigger order with the pslam doctrine that explodes shocked enemies, as obviously the trigger order can make a huge difference here. If the holy explosion trigger goes off first, it could start a chain reaction.

Giving up heal on crit from the regular relic Greatsword I rolled up would be tough, but not necessarily undoable.
