There's an Archer in my party, and I'm playing the party Wizard. It's likely going to come up that there will be a time when an enemy ends up behind the 10' diameter sphere of churning water made by Aqueous Orb and the archer will want to attack through it. Or a Fighter who's Enlarged might want to use his reach weapon through it.
The spell states that "[Victims inside] gain cover against attacks from outside the aqueous orb..." and I was wondering if the orb itself would provide cover from ranged or reach attacks to creatures on the other side of it.
Ranged Attacks Underwater: Thrown weapons are ineffective underwater, even when launched from land. Attacks with other ranged weapons take a –2 penalty on attack rolls for every 5 feet of water they pass through, in addition to the normal penalties for range.
from Aquatic Terrain apply? However, it still doesn't clear up the issue for reach weapons.
