Right, that I understand, it's why spectral throw is so comically short on modifiers.
What I mean though is, normally for any effect other than the actual hit effect of a projectile coliding with an enemy, be that an explosion, a secondary zone of damage, whatever it might be, will be listed if it's not simply a more or less damage multiplier.
For instance, infernal blow. it states that it deals:
Explosion deals base Fire Damage equal to 6% of the corpse's Maximum Life
Debuff deals 66% of Damage per Charge
Both damage types are included in that statement as it's just generic damage.
But cremation, if it's the same as detonate dead (sorry for all the corpse explosion mechanics but there aren't that many sources of secondary damage in PoE, apologies), deals a percentage of the corpse's life as damage, and does not include any other damage, be that base or added.
I guess that's where I'm getting hung...
