Stacking identical artifacts?

[Inigo Montoya]

hm would you please share how this works tinktank ?
because if that is true it should be fixed in the next patch because i think this result is not how forge boni were intended to work or johan ?

i have looked through sites.xls from sunraybe now .
it may be incorrect but there the maximum construction bonus listed you can get from sites is 20% .

so the maximum you should be able to get is 25% forge bonus from a ulm mastersmith , 50% from hammer of the forge lord and 20% from a construction site which adds to 95% .

so now even if all is added and forge of the ancients is up a 80 gem item should cost then :
80x0,5 for forge = 40
40 x 0,05 = 2

so the cheapest prize under really rare circumstances should be 2 gems for a robe of invulnerabilty / soul contract etc.

pickles statement underlines this too he got items worth 80 gems for 10 gems with 75% forge bonus + forge of the ancients up .

edit :
could it be possible tinktank that you discovered that in a dominionVersion pre 2.12 and johan and kristoffer already fixed it for 2.12 ?

Try forging a 5 gem item, Boron.

The formula rounds down, and this is why you can get to less than zero. I don't have the game running right now, but try a 5 gem item with a Smith with the Hammer while Forge of the Ancients is up. The cost will round down to zero. You don't even need a construction site. The Ulmish Smith with the Hammer will get construct the item for 1 gem, but with the Forge up, it will be free.

Eek Inigo is right - I was sure I had checked this too

Mind you that combo is better off forging 40 cost items for 5 than 5 cost items for 0 - saves 5 gems cf normal setup rather than one
