I find myself trying to avoid spells that create surfaces that can't be removed with fire because otherwise the VFX on the environment is perma. Using water only works for spots we don't have to return to constantly. It's particularly annoying if you cast any icy spell or a create water spell at camp, cause it doesn't go away. Using create water or tossing a water bottle to clean up is risky too, if you do it in the wrong spot. I tried to cover up my crimes as Durge by washing the blood into the river, but instead I just had blood and mud at camp for most of the first act. I totally ruined the Elfsong Tavern with an icestorm, now it looks like the place just got rocked with a hurricane level deluge. Pretty sure I did the same at the Last Light. It's super annoying that we can do nothing to get rid of those visual effects if we happen to create water at camp.
Shadowheart's spell Create or Destroy Water makes it possible to remove water and blood surfaces. If you use a higher level version of it it will enlarge the radius.
