Any castle with important rooms not warded against scrying and teleporting is asking for trouble. If I were running, I'd have all such important room warded in such a fashion. Hell, I might even have the whole castle warded in such a fashion.
Meh. Seems every fortress has unexplored caverns. Beside, warding is relatively expensive. While it's unlikely someone's going to successfully
teleport into the throne room, the original discussion was about things being taken at the town's gates. How about we just
scry on a servant, use some illusions to disguise ourselves, hop in near them, assume their identity and walk inside. I'm guessing you're going to suggest detection spells. Sure. Suddenly this kingdom is sinking huge portions of its wealth into spell-casting services.
A bonded item is superior unless you play in a very high magic environment where the loss of a potential item slot becomes significant.
Shrug. You can still enchant your item. So you can have a simple ring at 1st level, then have it turned into a
ring of featherfall later on. I also fail to see where it actually says it consumes a magic item slot. I could be blind, but I don't see a specific statement. Intent of the rules... unclear.
That's exactly my impression. My group just completed Crypt of the Everflame, and the extra spell per day was an impressive boon for the wizard.
The spontaneity is probably the biggest thing, even at low-level. I've had a
teleport go horribly awry with only one prepared, and the entire party ended up something like 20 miles off the coast, in the ocean. Ooops. Fortunately one party member was an incredible swimmer, and the rest were able to climb into a bag of holding. It was opened periodically to refresh the air supply. Still, the primary fighter had to swim for the better part of a day. Plenty of Con checks for fatigue and exhaustion, and even with the cleric reaching out to "fix" things periodically, by the time the party reached shore, it was
very touch & go. Not a given. This was before PFRPG Beta. Had my wizard been able to use an arcane bonded object, it would've been a non-issue.
There are lots of times when just ONE spell you didn't prepare can save the day.
