The 3rd level Druid spell Call Lightning says that it creates a 30' vertical stroke of lightning and that it can be used indoors. Are there any limitations (or advantages) to casting it inside? Ie, if I cast it in a standard 10' high dungeon corridor does it:
a) bounce vertically three times in the corridor (like a lightning bolt) until it reaches a full 30' length?
b) the spell fizzles because it cant create a full 30' stroke?
c) the spell damages the dungeon floor / ceiling for 3d6 as well, trying to extend to a full 30'?
d) the spell just does a 10' stroke with no side effects?
e) or something else?
