Any thoughts here? It might not matter in the end but it takes a move action to stand so at some point it might have an impact. Thanks.
Sorry, I thought I had answered this.
In all my time playing D&D, creatures that fail saves on Sleep and Slumber fall prone. Never even considered it any other way, figured it was a no brainer. (It is Hold Person/Monster spells where your victim remains standing in place.)
The real debate on Sleep would be whether they retain their weapon in hand. When people are knocked unconscious from going below 0 HP, there is no hard fast rule for them losing weapons, either. So both cases it appears to be a DM call. But if you get stunned, you drop your weapon...
I make people roll a CON or STR check (player choice) against DC15 to retain weapon in hand. Every action can be important when you wake up prone, so it seems fair to have a chance for something good to come out of it when you get woken up mid-combat.
