Evasion and confined spaces.....

[Infiniti2000]

On the subject of no saves, Id an NPC says they are going to heal a PC and instead casts a cause wounds spell, is it justified to deny the PC a save? I say yes personally since you were willing to accept the spell in the first place and werent trying to resist it.

No, definitely not. One spell is (harmless), the other isn't. They function differently when unconcious and therefore they function differently when not unconscious. There must be something about the spell being (harmless) or not that you know it when affected. When suddenly the "default" is to save, then you do so. It is not automatically suppressed like a harmless spell is.
