I have a question about Barnubus cave - I went ahead and turned off the two forcefields, but mostly that's because I'm a bit of a completionist, particularly in this game it seems that you'll miss some cool loot if you don't do everying.
Couldn't you just fly to barnubus platform, position yourself above the anti-dragon field, then morph to human so you fall through the field and onto his platform, then defeat him? Is there any reason you must turn off the shields?
