Hello.
In our current game session, the party is protected by the Life Bubble spell. There is non-magical acid on the floor of the room we're in, up to a foot deep. There is a debate on whether the acid would touch the players, who are covered by an inch of breathable atmosphere.
Pros to the "shouldn't damage us":
- Acid is an environmental hazard that isn't breathable atmosphere.
- Life Bubble protects against pressure while underwater, implying that the liquid doesn't touch the user.
- The fact that movement can still be constrained is easily chalked up to the outside of the bubble being impeded.
Pros to the "doesn't protect us":
- The spell description would say if that were the case. That's an awfully big thing not to explicitly mention in the spell.
- If your entire body is covered by air, your feet aren't touching the ground, so how are you walking?
- It is explicable that liquid can breach the barrier and be breathable, like Airy Water. Though one would hope the spell would state that.
This does, naturally, also lend itself to liquid contact poisons and the like. Any thoughts or outright rulings?
