Larian Studios Forums Divinity: Original Sin 2 Divinity - Original Sin 2 - Help/Tips/Tricks BedRoll *Spoiler on it's use*

I don't think it needs the stat bonus even.
It was impossible to heal out of combat in DoS1 without a healing spell, and this item being available early in the game solves that problem, which is great.
The stat bonus means an optimal player would want to pop it right before fights, which is a bit of a pain.

Also, the bedroll has no cast time or cost, and hits the whole party. If a fight ends, and a couple of your guys are about to die to bleed, poison, etc., it's a great way to stabilize them all.

If it also heals Undead, I suppose it makes gameplay (compared to Poison concoctions, weapons) a great deal easier.
How someone can go out of their way to call something like that "trash" (to get a few smart-ass points somewhere on the internet) is beyond me anyway, and it almost makes me want to jump at them... (And it lowers the standard of the whole board for me.)
