Artificer and craft reserve: so confusing

[Boci]

Okay, so I'm an artificer with the gold and XP artisan feats. At 4th level my craft reserve is 80. So I can drain it and make 2.5k worth of magical items for 937.5gp, right?

Okay, so I'm an artificer with the gold and XP artisan feats. At 4th level my craft reserve is 80.

Craft reserve can be used instead of actual Xp. That is its use.
Legandary artisan (that Ebberon feat that reduces XP cost by 25%?) allowing you to pay 3/4th XP cost instead of 4/4ths. Basically you pay 75% XP cost instead 100%.
So 100 XP costing item is only costing you 75 XP.

What are you asking with second question?

Are my maths right:
By spending all my craft reserve of 80XP, with both artisan feats, I can make 2.5k worth of magical items, paying 937.5gp in raw materials and emptying my craft reseve, right?

Don't forget, at earlier levels you would have crafted some as well. That makes the math harder(figuring your bonus for that level out, then figuring out how much cash you'd have, then rolling checks), but it's worth it.

But are my maths for level 4 right?

Not quite. You can make 2650 gp worth of magic items for 993.75 gp.

Okay thanks. I devided the amount by 0.75, is that where I messed up?

[Draxar]

Artificers do get confusing. Especially warforged ones, I've a long and complicated chart for the stuff my level 9 artificer will have made by the time he meets the party.

No, that's the right thing to do. I'm not sure how you got that 80/.75 = 100, though.

Normal: XP cost is 1/25 of the base price.

So, with no feats you can make 80*25= 2000 gp (base price) worth of items with an 80 XP craft reserve. They'd cost you 1000 gp.

With the artisan feats the XP and gp costs are reduced by 25%.
That makes 80 XP equal to 80/0,75= 106,67 XP.

106,67*25= 2667 gp

If you make an item with a base price of 2667 gp you would normally pay 1333 (2667/2) gp and 106 (2667/25) XP. With the feats you pay 1000 ([2667*0,75]/2) gp and 80 ([2667/25]*0,75) XP.

(On a side note, you usually round down in DnD, so I think you could get away with making a base price 2699 gp item with your 80 XP craft reserve.)

Thanks, this is just what I needed. So with the two artisans feats, assuming your craft reserve is X, can you craft 33.3375x worth of magical items for 12.5x gp, or is such a formula just wistful thinking?

Looks right to me.
