I have no idea how to properly factor the total cost of an Enchanted Weapon, and I'd like help doing so. I've read so many things and it gets confusing when I begin to read parts on how I "multiply by design" sort of thing. Adding base values than multiplying by bonuses or something... I just don't understand it. I'm hoping I can just give the information I'd like and someone can walk me through a detailed process as to how they got to the final cost.
Large Morningstar: 8gp
Masterwork Quality: 300gp
Fire-Forged Steel: 600gp
Cruel [Enchantment]: +1 Bonus
Defending [Enchantment]: +1 Bonus
Furious [Enchantment]: +1 Bonus
From the way I understand it, the total of +3 Bonuses would bring it up to a value of 18,000gp. The rest is a total of 908gp. So it's final cost should be something like 18,908... right? Because some things I read online say I have to take it's +3 Bonus and square it, than multiply it by 2,000?? That's (3^2)2,000 or 12,000? That's a lot less than the 18,000 for a +3 Enchantment? I also read that I may have to do something like add the Masterwork Cost plus the Fire-Forged Cost, plus the weapon's base cost and multiply this by two? Something of (300 + 600 + 8)2, or (908)2, or 1,816?
So does that mean it's actually 13,816; (12,000 + 1,816)?
I mean five grand isn't that much, but I don't want to overpay / underpay either. I want to play the game right, and it's just so confusing with this part.
Essentially this weapon is going to be used with my Large Barbarian.
Cruel will allow me to gain +5 Temp HP everytime I fell an opponent. Defending allows me to transfer some - or all - of the Enchantment Bonus on the weapon's Attack / Damage Rolls toward an AC Bonus (A total of +3). And Furious kicks in when I Rage. It bumps the Enchantment Bonus up +2 past it's normal value, raising it to a +5. That means I can gain a total of +5 AC when raging, which really helps subside the -2 AC Penalty. The Fire-Forged Steel from UE allows me to use a Full-Round Action to literally superheat the metal by holding it over a fire. When I do this, for the next two Rounds I can cause Fire Damage as well. I just think it's a neat aspect to have.
So which cost is right? 18,908 or 13,816? Or is neither correct?
Lastly, when it comes to the Craft DC, I need to multiply this by 100 so that I convert into Silver Pieces, so either 189,080 or 138,160. But I only require 1/3rd of this, right? So either 63,026sp or 46,053sp. But those are absolutely insane DCs?? How the heck is anyone supposed to meet those?? I mean are you literally spending years crafting these dang things??
I read somewhere you can - instead - have it's total time of creation be equal to 1day/1,000gp. So a weapon costing 18,908gp would take 19 days to craft, since it's a left-over of 908gp at the end?
This is why I'm so confused. I've read so many different things from so many different sites and sources that I have no idea what is actually correct. So if someone could do a step-by-step walkthrough as to how and why they got to their final cost and DC, I'd really appreciate it.
