Hey guys,
my problem is poorly described in the topic, let me fix that here.
So my Slumbering Tsar party recently encountered a single Basilisk and had some bad luck with his petrifying gaze. On his first attempt, the Basilisk picked three out of six with a single gaze.
So the party traveled back to town and had a high level mage npc destoning them using Stone to Flesh. Two people beat the DC 15, one didn't and died. In his presence of mind, the cleric instantly reacted and cast Breath of Life to save him.
That's where the problem is. Breath of Life does not save creatures slain by a death effect, so... is a failed Stone to Flesh considered as a death effect?
I, as the GM of this party, intervened and said, that it would not be possible to save the fallen comrade that way. In terms of my unterstanding, a death effect is a spell or effect which instantly kills you regardless of hp or other conditions, just like Phantasmal Killer or Symbol of Death.
It's not mentioned in the description of the spell, so how would you consider the ruling to be here? Is my argumentation going the right way or did I fail to see something important? Please help me and let me know what you think! Thank you :)
