I have a level 9 human druid with the Natural Spell feat selected. Since I live most of the time in animal shape, I would like to know:
Is another caster able to counterspell me while I'm in natural shape?
If the answer to previous question is no: considering the description of the Natural Spell feat, a bear will cast the same spell in different manner than a snake or a lion, what happens if a druid does not know a particular animal, can he counterspell? For example: two druids are fighting, the first comes from the Savannah, the second from icy north. The first get transformed into a rhino and starts to cast: is the latter able to understand what the rhino is launching?
