Magical Item advice!

[Garion Beckett]

Ok... I am the GM of a very high lvl game with mythic and I am trying to build an adventure for them. However I am having trouble trying to make an item I want the main baddy to have. If anyone remembers 3.5 there was the undead book of Liberia Morris that could give necromancers a series of Corpsecrafter feats that gave all the undead a boost in attack power and health. Now I want to make cloak that grants all of those feats.

I don't understand the question you're posing.

Are you asking how to make the book function as if it were a cloak? If so, just take the 3.5 item and treat it as a cloak. The only difference is that you would cut the price in half (as it's a slotted item versus a non-slotted item), and even that's not really relevant if you want it to not be something the PCs acquire (i.e. it's cursed or only functions for specific individuals).

Are you asking how to get the book mechanics to function in the Pathfinder system? If so, that's not really relevant when you're the GM and you can create whatever you see fit. If you want a cloak that grants a bunch of feats and benefits for summoned/animated undead, then do it.

Some more explanation as to what you're having trouble with would go a long way here.

Will the PCs get it? Don't give it anything you don't want them to have.

Will the PCs not get it? Give it whatever you want it to have, and don't sweat the details. (Something like "cursed to automatically inflict X negative levels on people who don't match some trait of the main baddy, which cannot be removed as long as the item is worn" will usually discourage people well enough.)

What i am trying to accomplish is trying to add a series of feats to a back slot cloak. The only reason for the PCs to get it is to sell it because none of them are necromancers. Lol so the reason i am asking is to find an appropriate sell/creation price. If they decide to use it then it would be a legal item

There are a series of 8 feats that grant undead more HP, damage, attack, natural armor, cold damage, death throws, and channel resistance.

How would i do that?

This Ioun stone grants the endurance feat and costs 10,000 gp. Now the endurance feat is generally a pretty weak feat so you may want to double that base price. By going from unslotted to slotted cut the price in half, brining you back to 10,000 base price per feat. For additional effects on the same item, you multiply the price of all but the most expensive effect by 1.5. Since they are all the same price just multiply all but 1 by 1.5.

For eight feats you would be looking at 1*10,000 + 7*10,000*1.5 = 115,000 gold.

That's just a ball park but to me that price makes sense.

[GM Rednal]

There is no specific price for feats granted by magic items, and you have to be careful about allowing that or people could end up with way more feats than they should.

That said, "weaker" feats (like proficiency with a weapon) tend to run around 5,000 GP each, and stronger feats should probably be at least twice that, and at 1.5x price past the first (as explained above). As a cloak, it would also interfere with the ever-popular Cloak of Resistance, so you'll need to decide if the feats should be an additional effect to that, or if players will have to forego that fairly common defense in order to make use of it. ...Either way, that's probably a 100k item minimum (plausibly a fair bit higher), and actually making it is as simple as saying "The wearer gains the benefits of the following feats as long as they wear this cloak: Blah blah blah. Any undead you created that benefit from the effects of these feats are destroyed immediately if the cloak is removed." (Because you probably don't want them tossing it on, raising undead minions, and then switching to another cloak.)

Pricing out feats are going to be hard. Putting out a aura that buffs creatures you can sort of price out by figuring out what it would cost with a permancy for that spell type. Then adjust to where you're happy.

[MichaelCullen]

Priced as I suggested about it comes out to a little over a quarter of a 17th level PC's wealth by level. To me this seems about right.

One issue the PCs may run into is finding a buyer if they choose to sell. They would only be likely to find someone with enough cash in a metropolis. And depending on the party's morals, they may not want to sell it to the type of person willing to buy it. They may need to settle for a much cheaper sell price to prevent if from falling into bad hands.

Or you could introduce an npc that can convert magic items. Ie this cloak costs 115k, the crafter can convert it into another cloak that costs a similar amount. With the cost of his labour it'll be cheaper than buying a new one, takes a powerful item of evil out of play, and gives them something more than just some gold.
