Sacred Soil, Earthly Star etc. all affect party members, so if you are in an alliance, it can be confusing to know which of these spells on the ground will actually affect you, especially if multiple scholars/astrologians cast them at the same time.

Having the spell effects appear differently when cast by party members would make this easier. Perhaps the ground can have a green circle, or the spell effects of non-party members be faded/greyed out.
