@JeremyECrawford Fiendish Vigor would seem to be a game-breaker. 1st Lvl Warlock with hundreds of hps.

1. Warlocks get invocations at 2nd level, not 1st. 2. Temporary hit points don't stack. 3. A spell doesn't stack with itself. #DnD https://t.co/HuUStnB7re

@rachitmodiSo as stated by your point #2, Dark One’s Blessing does NOT stack with Fiendish Vigor? That's correct.
