Well, assume we use the 3.5 amulet of fist but with pathfinder pricing on it. When going past +5 simply double the price of next enchant after it (so +6 version costs 200,000gp and +7 costs 400,000gp). What comes to amulet benefit more people with multiple natural attacks vs 1-2 ones, then is your choice do you get item (despite expensive) to enchance your natural attacks or not. But read; in pathfinder version reads you do not need +1 or higher enchant to have weapon enchants on it.
Well, just to clarify - the PF version of Amulet of Mighty Fists costs 2x what a normal magic weapon would cost in 3.5 - +1 costs 4k (vs 2k in 3.5), +2 costs 16k (vs 8k), and so on. If you follow that logic, then a +6 weapon - which costs 72k in 3.5 - would cost 144k in PF.
Considering as paragon your natural attacks already count as epic (having +6 enchant) for DR bypass purposes. Then you can use enchant natural weapon spell/scroll (or even item which holds charges of said spell) on yourself to get +5 bonus which may be cheaper option to get raw +hit and dmg numbers up while use amulet purely to get special qualities to your unarmed strike (ghost touch would be top on the list as sacred watcher).
Wait. Back up. Where does it say that? That was one of the major concerns I had, being able to bypass DR/magic. Also, I'm guessing you're suggesting Ghost Touch because Sacred Watchers are incorporeal, and thus cannot interact with non-Ghost Touch items? I took a feat for that:http://www.realmshelps.net/charbuild/feat/Ghostly_Grasp
If there's another reason I should be taking Ghost Touch...?
Heck, you can pick Extra Spell feat and learn magic fang spell from druid list to your sorcerer list and treat it as arcane spell you learned.
Actually, if you read the Unarmed Strike entry under Monk, it says a Monk's unarmed strike counts as both natural weapon and manufactured weapon for the purposes of spells and effects - so both Magic Weapon and Magic Fang can enhance it.
The problem with those spells is that they merely confer the numeric bonus, which is the lesser of the two things I want - I'm mainly aiming for weapon properties. The big two I'm going for right now are the Stunning Surge property (from MIC) and the Martial Discipline Weapon property (this from ToB).
Arguably -- you could always just take two Amulets*: One that gives you +5 Enhancement, and one that gives you +5 in magical properties. Even with the 2x cost levied to Amulet of Mighty Fists in pathfinder -- you're paying the same as some other guy who builds a +10 sword -- and it effects your normal unarmed AND your unicorn horn.
*Obviously not literally wearing two amulets -- but either merging them with the rules for combining magic items, or one using another slot (belt and gloves would both be easy arguments).
Yes, but even if you go with the fact that you are paying the same price, two things.
A: the rules that Zaer has stated for combining magic items say that you can combine any two or more by paying double the cost of the most expensive item to cover the merger - so if I want to combine 2 100k items, that ends up costing 300k (100k x 2 + 100k), whereas the +10 weapon would simply cost 200k, because it's only 1 item. You could theoretically solve this by having 2 different items in 2 different slots, but that doesn't solve the bigger issue...
B: You can't have a magic weapon of just straight properties. You require at least +1 in enhancement bonus in order for the properties to function. So you can't stack +5 of weapon properties onto one of the items, you can stack a maximum of +4. Now, you can divide up the bonuses however you like, but the fact remains that you need that basic +1.
I still don't quite understand why it is we can't just use the Necklace of Natural Weapons from Savage Species as-is...it costs the same as a 3.5 magical weapon.
