So there *is* an in-game way to revive an unconcious companion.

I just found a Scroll of Revival. "Though no scroll can reach beyond the Shroud to restore ones fallen companions to life, this spell can prevent their passing, for it restores to the incapacitated the vigor required to get to ones feet."

Spell effects listed are "Friendly AOE: Revive with 177 endurance for 1.7 seconds (base 1 second) (+15 accuracy)"

Theres a priest spell and a paladin ability that I know of that gets a knocked out companion up in battle, but as far as I know if someone is killed, they are dead forever.

Yup. I've just heard a bunch of people saying they have a bug where party members get knocked unconscious but combat never ends so they can't go on. I'm thinking if that happens to me, I can at least try this scroll/those spells.

There is also a priest spell that prevent death, if you're in trouble. Last 20 or so seconds though.
