Does Warlock with Dark One’s Blessing gains several times temporary HPs from Area of Effect spells?

@VNarvekRAW Fiend’lock kills several hostiles at once (fireball), Dark 1’s Blessing: Gains several times THP then normal. Correct? nope – temp hit points don't stack

@VNarvekI know, my question is after the timing. AoE Kills at the same time=adding them at the same time, not one after another. the system still queues them up

@VNarvek @mikemearls Just got a different response from @JeremyECrawford My understanding: general rule: no stacking, fiendlock specific: stacks Dark One's Blessing doesn't break the stacking rule. Each dead creature gives temp hp, but the temp hp don't stack.
